The Year of the Delphinium

Delphinium - Curtis Jones

My snow covered flowerbeds look like a black and white photograph. I love the serenity of winter, but I am also eager for the activity of color to come. Direct sowing is the easiest way to sow but starting flowers early (indoors) satisfies my gardening mind and pays off with early color in the garden. This is especially true when it comes to perennial flowers, specifically delphiniums.

The National Garden Bureau is calling 2016 “The Year of the Delphinium”, and I agree. Delphiniums bring coveted blues, deep purples, pinks and whites to the garden, not to mention they are pollinator magnets. These stand-out perennials (hardy to USDA zone 2) got their name because ancient Greeks thought the spur on the back of the flower resembled a dolphin’s snout (the Greek word for dolphin is delfini.) In the south, these flowers are grown as annuals because they don’t perform well in prolonged heat and humidity (much like myself). Delphiniums are excellent cut flowers with a variety for every application. I love both heirlooms we carry—the traditionally tall 3’–6’ Pacific Giant, and the short and sweet Butterfly Blend that reaches just 12”–16”. Both are deer-resistant. Their close, more delicate cousin, larkspur, can be used similarly, and also comes in some hotter pinks and reds.

I prefer to start most perennials, including delphiniums, early and indoors, because I am more likely to get blooms the first season. You can start most perennials extra early (10 to 12 weeks ahead of your average last spring frost), although they may need to be potted up into larger containers once or twice before you transplant them outside. Delphiniums in particular should be started no later than 6 weeks ahead of your average last spring frost. Soaking seed for 8 to 12 hours can help speed germination, as well as darkness; so bury seeds ¼” when you sow. Also, delphiniums germinate best in soil temperatures of 70°–80°F—a tall order for our cool spring soil, which is another good argument for starting them indoors. Delphinium seeds should be fresh, as they are a species that doesn’t hold over as long as some others.

These extra steps will reward you come late spring! Pacific Giant spires look stately planted in odd numbers of clumps in the back of my sunny flowerbed. Their sculptural form adds structure to the bed and helps guide the eye. Despite being straight and tall, the petals and leaves are lacy and soft, adding a delicate touch. I prefer to stake mine since we can get some big winds here on the Colorado Front Range. After they flower, you should cut them back, fertilize with a phosphorous-rich, liquid fertilizer, and you will often get a second flush of flowers. I cut them down again at the end of the season and thank them for their spectacular display one last time. Next spring, look for the strongest 2–3 shoots in a crown and cut out the others; this is a good time to fertilize with a balanced, or phosphorous-rich liquid fertilizer. Dividing clumps every 1 to 3 years or so can also keep these cool-hued beauties from overcrowding so they can look their best.

Perennials are known for demanding a little more patience to see their full potential, but the up-front effort has long lasting results. Remember, if you don’t want to wait a year for blooms, sow extra early indoors to increase your chances of seeing that first year color. Once established, perennials give years of beauty with minimal maintenance, and are great when used to give a garden consistent structure. Growing perennials from seed is also advantageous because it gives plants time to grow up in your garden and adapt rather than being spoiled in a greenhouse, and in my case, shocked by the real world garden. Plus, buying seed versus potted plants really stretches one’s garden budget! The countdown to spring continues!

Garden Planning Time!

onion starters

When I lived in California, I would joke that I gardened until Thanksgiving, rested until New Year, and then started gardening again. Gardening in Colorado is a completely different ball game! The ground is frozen, the air is cold, and we’re not even through the worst of it. With these cold temperatures, it is sometimes hard (even for me) to remember to start sowing seeds now—spring will be here before I know it!

The new catalog is out, and I have been enjoying it (and our new coloring book) cozied up by the fireplace with the dogs but, goodness, I need to get planning and sowing! This year, I want to add foxgloves, Canterbury Bells, and delphiniums to my flower beds; artichokes, celery, and onions in my vegetable garden; and I would hate to miss out on our pumpkin on a stick ornamental eggplant for fall décor. But, if I want to enjoy these plants in June, I need to start planning now. Here are a few things that benefit from an early start indoors (10 to 12 weeks before our average last spring frost):

Artichoke Columbine
Celery Echinacea
Eggplant Little Bluestem Grass
Onion Heliotrope
Rosemary Lavender
Penstemon barbatus

I use several of the printable charts available online to help with the planning process. They keep me so organized! Our sowing guides are also extremely helpful. I will get out my planning charts and a calendar, mark my average last frost date, organize my seed packets by number of weeks until average last frost, and get to sowing!

when to sow

If you don’t know your average last frost date, contact your county extension office or a reputable local garden center to find out. Using that frost date, I can count the weeks back to know when to sow or stratify and mark it on our handy Indoor Seed Starting Worksheet. So here I go, coloring book down (for now); let the planning and sowing begin.



Judy’s “Under-Appreciated Treasures”

Canterbury Bells


We all have things that we see beauty in, while others may not yet—a vintage sweater, an independent film, or a local band. For me, it’s plants. There are a few “under-appreciated treasures” in our line that, from a business point of view, I should have dropped years ago. I still offer them because I think they are fabulous, and I know everyone will eventually think so, too! These varieties are in my garden every season and hopefully, they will find their way into yours.

My favorite annual flowers are so easy to grow, and display beautiful, showy colors! California Bluebells bloom a near true blue within weeks of sowing. I love a scented garden, and for me, Sweet Pea High Scent is a must! Sunflower Vanilla Ice is a pale yellow showstopper during summer, and a fall bird magnet. Hyacinth Bean Ruby Moon not only attracts hummingbirds to its purple flowers, but the lilac/purple pods that follow are also strikingly beautiful . Marigold Signet Lemon/Tangerine Gems bloom non-stop, and are covered in cute, yellow and orange edible flowers summer until frost. Add them to your vegetable garden near the tomatoes!

In general, biennials are under-utilized likely because they don’t bloom until their second year, but if you sow them every year, you can enjoy them every year! I grow Canterbury Bells because they are dramatic, elegant, and make excellent spring cut flowers. Foxglove Gloxiniiflora Blend is a winner for areas of part sun, and blooms in spectacular multi-flower spikes, each flower having its own beautiful, speckled detail on the inside.

It’s true that perennials require a little more commitment and patience, but I wouldn’t have a summer pass without Chocolate Flower, Nicotiana Indian Peace Pipe, Painted Daisy Robinson’s Blend or Penstemon Dazzler Blend. Chocolate Flower is native, loved by beneficial insects, drought tolerant, and literally smells like chocolate. Need I say more? Nicotiana Indian Peace Pipe reliably returns next to my porch wafting it’s intoxicating scent through the screen, inviting me outside. The white flowers glisten in the moonlight—very romantic. Painted Daisy Robinson’s Blend is a cheery long-lasting cut flower that also attracts butterflies. Penstemon Dazzler Blend is a striking blend of pinks, blues, and purples and is usually humming with hummingbirds. It’s native, drought tolerant, and looks stunning in a rock garden. I love the upright habit and beautiful colors.

These days, culinary palates are more open to the new and unusual, so I can think of only a few little-known and undervalued veggies. Beans are a must in my garden—the fresh flavor is so superior to store-bought. French Filet Beans are thin, tender, and always sweet and succulent.  For a standard bush bean, Jade shines. Jade is disease resistant, a beautiful deep green, and a consistent producer. Orient Wonder Yard Long Bean is also a favorite. Yard Long beans are just beginning to be seen at farmer’s markets. Talk about bang for your buck, the 1-3 foot pods are so delicious, and a definite conversation starter/curiosity. My favorite beet is given an unfortunate name, which may be influencing its lack of popularity—Bull’s Blood beet. It is truly a gross name, but it has brilliant red roots, and the greens are gorgeous in the garden and on the plate.

They might not be Botanical Interests’ top sellers, but luckily gardening isn’t a popularity contest. I’m keeping these varieties for their uniqueness, their high value to me, and to be able to share them with those of you who love them as much as I do.

Your Gardening Stories Inspire Us

Judy catalogI’ve been a gardener since I was little. My Mom and Grandfather were my mentors. I loved to weed and go to John’s Garden Center in San Jose, CA with my Mom. Gardeners aren’t all the same. Sure, we share a common interest, but everyone has their own gardening story—why they started gardening and why they continue to garden today.

Curtis and I, and the whole Botanical Interests team, wanted to know your stories, so we asked, “What is your gardening story in four words or less?” The overwhelming response (hundreds!) made us happy to see that so many people share our passion. Being inspired by just the four words, we asked for the whole story. And boy did we receive them! As we read through your thoughts and memories, a mosaic emerged of different experiences and personalities.

Throughout the catalog, you’ll read a handful of these personal gardening stories, and you may even recognize yourself in them—we certainly did! Some want to ensure their family eats clean, organic food, while others enjoy creating a beautiful landscape like an artist. Many of you were taught to garden by grandparents and continue that legacy by feeding your own families and building gardening communities. Like us, almost all gardeners shared their love of nature and how communing with the earth centers their soul. You’ll read these gardener’s stories and more! Thank you for taking the time to share your lives with us.

This year, we’re excited to share with you, 47 new varieties with something for everyone. We added two new basils, Lemon and Sweet Thai, for the experimental cooks; the stunning Night and Day snapdragon for ornamental gardeners; Showy and Common Milkweeds for pollinator-friendly gardens; and two popcorns, Dakota Black and Robust Pop 400MR, for something fun and unique to grow. We also increased our organic selections; over half of the new varieties are either organic, heirloom, or both. And for those with larger areas, we even added seven new large packets.

Just as we were inspired by each narrative, personal history, anecdote, and even a poem or two, we hope to continue to inspire and educate the gardeners within all of you.

We’re very proud of 2016 catalog. Request a copy today and discover new and unique varieties, read stories from our customers on why they garden, and learn about sowing temperatures, Scoville Heat units, and more.

Fall Gardening is for the Birds

Over the years, I’ve noticed there is a pattern to my gardening. In the spring, gardening is full of excitement, so much so that my big yard even feels small as I search for spaces to poke in new varieties or add more color. By summer, however, my yard feels so large that keeping up with deadheading is nearly impossible. While deadheading spring and summer flowers keeps plants blooming and branching, at the end of summer, you can leave seed heads on for migrating and over-wintering birds, who gladly consume the seeds for much needed calories and nutrition.

Leaving seed heads doesn’t just cure your late-summer gardener guilt, it is also beneficial to the plants, too. By waiting until the following spring to do your clean-up, any still living tissue is saved, preventing a wound which can be a weak point for possible infection. Those branches also collect leaves and snow, naturally mulching the crown of the plant, and in turn providing cold protection and moisture. The sculptural aesthetic of standing stems and seed heads is referred to as “winter interest” by landscape professionals; a term you can use freely if you are accused of being a messy gardener.

As we think about fall-sowing flowers, here are some tips if you want to design your garden to be more inviting to birds next year.

  • Live on the edge. Edges are the spaces where two habitats meet, like where shrubs meet a garden, or where shrubs meet trees, creating varying heights. Birds love the edge because there they find protection from the elements and predators, usually a diversity of food, and a lot of different perches. If you are designing a new edge or hedgerow, consider a meandering natural line instead of a straight line, and adding shrubs that hold fruit in winter. Add a border of perennials and annuals from the list below to these edges to provide winter seeds.
  • Leave a few snags. A few dead branches (provided they are safely away from structures and high traffic areas) attract birds for nesting, feeding, and perching, and offer winter protection from the elements.
  • Winter water. Give birds water in the winter by providing a heated birdbath or place an immersible de-icer in a birdbath or shallow dish. A low-tech option is a covered black container with a small hole in the top for birds to sip out of. The container collects solar energy keeping water from turning into ice until temperatures dip below 20°F.

If the winter interest method just doesn’t fit your comfort zone, do your usual fall clean-up, but save some seed heads to create a bird feeder wreath, or simply bundle and hang them near a safe perching place for the birds to enjoy.

Here are some flowering plants that you and the birds are sure to enjoy.

Garden Journal Notes to the Future

Botanical Interests Trial garden

Fall is approaching. The angle of the afternoon sun creates a beautiful glow in the garden. I love this time of year; it is a great time to sit in my garden and reflect on what I like and what I want to change. I need to divide my crowded delphiniums and give them to a neighbor, sow more leeks next year, remember to sow a fall succession of peas, and plan for more color in June. While my landscape boasts every color of the rainbow in April and May, come last June it was ablaze with yellow, and only yellow. So now I sit, enjoy, and make these notes in my trusty garden journal.

Taking some time this fall to review what you did or didn’t like in your garden will make a world of difference for next year. Having firm ideas of what to change will make seed ordering a snap when you receive our catalog this winter. Not only do I make notes to remind myself what to do differently next year, but I also use garden stakes to mark the space noting the variety I want to add and its bloom period (you can search by bloom period or color on our website, too!). I also like to print out a photograph of my garden and draw in plants to add, leaving a little room for new varieties. These techniques really help me visualize the changes I want next year, and get started on this fall. That’s right, this fall. In addition to dividing and moving established plants, I will sow some flower seeds now, as several annuals and perennials perform best when sown in the fall.

The coming of fall usually feels slightly bittersweet, but after a hour of dreaming and journaling in the garden, and watching my goldfinch friends enjoy the sunflowers, I feel excited for the changes to come, and the garden feels like a fresh palette.

Enjoying my bee garden

been on lavender

While my garden is my reprieve­­­­­—a place to recharge—I like to share it with my sweet, bee friends, and at this time of year the garden is a-buzzzz with bees. I need these hard working, fuzzy heroes to pollinate. Did you know that there are over 4,000 native species of bees in North America? Talk about diversity! Some bees are generalists, like the European Honey Bee, collecting pollen from a number of various plants, while other bees are specialists, pollinating specific plants–like squash bees with squash and pumpkins.

Over the years, I have made little improvements to make my garden more inviting to bees—a few seeds here and there, larkspur, borage, thyme, and asters to name a few, which keep the garden humming. A well-placed shallow water dish with rocks placed on it for landings, provides needed water for busy, thirsty bees (and butterflies), keeping them in the garden longer. Growing flowering plants that bloom from early spring to frost gives bees year-round food in the form of pollen and nectar. I also added a smattering of natives, which generally provide the highest quality food for these fuzzy foragers. Your space doesn’t have to be large; a container on a high-rise patio or a window box can still attract a plethora of pollinators.

Bee population decline is a serious issue that we can all help to remedy by providing food, water, and habitat. Most Botanical Interests flowering plants provide bee food and our Save the Bees specific flower blend provides color and food for foraging bees from spring until fall. We bee-lieve a small seed can make a big improvement in bee populations.




Bee Happy Seed Collection includes flowers that attract and nurture bees in your garden.










Save the Bees Flower Mix provides food for many of the over 4,000 bee species in North America. With so many gorgeous flowers and tasty herbs you’ll appreciate this bountiful mix as much as the bees! Available in regular and large packet.








DIY Tomato Supports

tomato supports DIY

In Colorado, tomatoes are finally here! Our May was cold and wet, which is unusual for   sunny Colorado, setting plantings and harvests back 2 to 3 weeks. So while our tomatoes usually start coming in around July 4, it is now the 3rd week of July, and I finally have tomatoes.

Tomatoes are one of several crops that are best grown in your own garden. The homegrown flavors of picked-when-ripe, fresh tomatoes, snap beans, peas, or corn are worth the effort. This year I tried a new support system with my tomatoes, and so far it is my favorite because it is easy to set up, use, and store. And it’s reusable year after year!

My new method is similar to the stake-and-weave method, but it’s easier. I used sturdy wire mesh panels (concrete remesh or hog panels work well) attached to 8’ t-posts. I hung the mesh with the bottom about 1’ above the ground and attached it to t-posts using zip-ties. I planted my tomatoes 2’ apart in line with the support. While I am in the garden, I can simply weave the tomato tops back and forth through the grid pattern. I do this once a week, maybe twice, while I scout for ripe tomatoes, pests, and disease. At the end of the season, I can simply remove frost-killed vegetation, snip the zip ties, pull the t-posts and store the panels and t-posts flat, outdoors, for years of use. These are also great for creating permanent trellises rotating between peas, pole beans, melons, watermelon, cucumbers or any other climbers. I love seeing my tall, thin, yet strong wall of tomatoes. This system is simple, space efficient, reusable, and keeps plants off the ground, improving airflow and reducing the risk of soilborne diseases. It helps make weeding a snap!

Every year my gardening efforts open my eyes to new opportunities and ideas to improve colors, flavors, and methods—my skills and enjoyment grow right along side it.

3 Steps to Beat the Heat

Judy's garden


Here in Colorado we jumped from a rainy, cold May straight into the dog days of summer. Out comes the shade cloth, sun tea, and strategies for keeping your garden (and you) thriving. Here are some things I keep in mind during the hot summer months.

First, I harvest early and often. Plants recharge overnight, and in the cool of the morning they are full of life and water again, giving you the best flavor and shelf life, not to mention a lot less stress for you and the plant. Since plants strive to reproduce by creating fruit with seeds, harvesting that fruit redirects their energy to producing more flowers and fruit. So if you harvest plants like zucchini and snap beans often, imagine how many zucchini muffins you can make for your friends and neighbors!

I also successively sow throughout the summer months. In general, crops germinate best in soil temperatures under 85°F, but squash, melons, cucumbers, pumpkin, and corn are my “go-tos” when looking for warm temperature germination. If your soil is hot, hot, hot and you want to grow cool season crops, consider starting them inside, hardening them off, and transplanting them just like you do in the spring. Our sowing guides are very helpful for planning. In the case of cool season crops like lettuce, spinach, and carrots, look for heat-tolerant varieties or sow them where they will get the benefit of late afternoon shade from another plant. You may also want to review our article, Edibles for Partial Shade for ideas on what crops produce well in shade.

Lastly, water and fertilize wisely. The best time to water and use liquid fertilizer or foliar feed is in the morning. If you live in an area with low humidity, evening is also a good choice. High humidity areas are more likely to have fungus issues and so the prolonged overnight period is best spent dry. Plants recharge in the morning and shut down in the mid-day high heat. Water also evaporates more quickly in the high heat making your effort to fertilize and water less effective.

Using these best practices should keep your garden producing and you enjoying it!

To plant a 6-pack or to direct sow…that is the question


I was at our local garden center the other day with a gardening friend, Sue. We marveled over the 4” double impatiens, “ooohed” and “aaahed” at the hanging basket of fuchsias that looked like dancing ballerinas, and made jokes about the extensive, but wonderful, choices of hot peppers.

As we neared the back of the greenhouse, we came to the area filled with 6-packs. Now, before I start ranting, I must disclose that I had more than a couple of flats of 6-packs on my cart before the days end, but there were things I would not buy in a 6-pack, as there are many herbs, veggies, and flowers that just don’t transplant well. When Sue picked up a 6-pack of parsley, she didn’t realize she was about to receive a lecture. She is a good gardener and sows seed often, so I was surprised by her choice. Parsley is one example of a plant that doesn’t transplant well. Parsley grown in a warm greenhouse, and then transplanted into a cool garden can often go into shock and bolt. The radical change in temperature makes the plant think it is fall and should focus its energy into seed production instead of leaf production. Parsley is a cool season herb that prefers to germinate in cool soil, and then grow in warm soil. It really does best sown directly in the ground in early spring.

But explaining all this to Sue just got me going. I noticed 6-packs of carrots, lettuce, fennel, squash, corn, and radishes! All of those vegetables are so easy to direct sow, and do so much better sown directly in the ground. Transplanted seedlings go through a period of adjustment, which can also lengthen the time it takes them to reach bloom or harvest.  Some crops are so quick; the transplant shock really slows things down. Some plants have a long taproot that just gets tangled up in a container, and therefore, won’t transplant well. Direct seeding is not only easier and better in many cases; it is cheaper! There are things like perennial flowers, tomatoes and peppers that I like to start indoors to get a jump on my area’s short season, then transplant them out into their final garden home. It is important to understand which crops have an advantage being transplanted versus direct sown, in order to avoid slow, weak, or poor yielding plants.  I explained to Sue that I worry about beginning gardeners that may use these 6-packs, then give up when they are not successful. I ranted for a fair amount of time about the pitfalls for new gardeners, when Sue reminded me of the resilient and positive spirit of gardeners. “It’s all trial and error. Gardeners never give up. We learn and we grow and then we plan next year’s garden.” She’s right. But just in case, here is a list to consider:

Plants that perform better when directly sown are usually faster crops; ones that do not like their roots disturbed, and all root crops.

Root crops (beets, carrots, radish, rutabaga, turnip, etc.)
Squash (summer and winter)
