Bees love this!

Jul 20, 2018

I grew my hyssop plant from these seeds; the seeds went straight into the group in my Zone 4 climate. They grew the year I planted them but it was the following year that they really exploded into amazing, flowering plants. And yeah, the bees and other pollinators love hyssop! Really a great plant. Thanks to Botanical Interests! Never had bad seeds from these guys; I've been buying from them for years.

Greetings from Zone 7a

The package said to expect sprouts to emerge in 14 - 31 days. I had sprouts in four days. It was a very exciting and unexpected surprise!

Its brought some hummingbirds

Aug 22, 2020

Since it's been growing true hyssop, I've had humming birds check out its flowers. I cant see much as it happens so fast, but they hover in the direction, and right next to the true hyssop for a few seconds and flys away. Everytime I see them, it's quite amazing.

0 germination

Unfortunately 0 germination. Almost all the herb seeds I purchased had this result despite planting in several locations.

off to a great start

I started these indoors under lights and had good germination. Seedlings rapidly grew into satisfyingly robust seedlings. I had them in quart pots all summer and there were more blooms than I'd expected from a first year perennial. Can't wait to see them next year! I also did some winter-sowing with them; those plants were much smaller and did not bloom, but hopefully will make it over the winter and surprise me next year.

Sowed five packets--got one blooming plant

Jan 20, 2022

Last spring, in late April and early May, I sowed five packets of these seeds in a location where other flowers had grown well the previous two years. In late summer, I could find only only one hyssop plant in the that area. (Other flowers had grown in the area during the spring and summer--I think possibly from seeds of flowers which had grown there before.) The instructions for sowing these seeds say "Press into surface". I carefully raked them into the soil with a garden rake. I don't think this is the reason why I got only one plant from five packets of seeds.

Salvatore from VA

Owner Response: Hi Salvatore, We are sorry you had difficulty germinating these seeds. A customer service agent will be reaching out to you via email to help. It is important not to bury these seeds as the seedling can run out of energy stored in the seed before reaching the soil surface for sunlight where it can make its own energy. Other times we may give instructions that a seed needs to be pressed into the surface is because light aids germination and in darkness, the seed will remain dormant. Rest assured that quality is very important to us and we have our seeds tested regularly by a third-party laboratory to ensure germination meets federal and our own standards. We sure hope you will try this lovely native plant again.

The best old world hyssop I can find, thank you.

Great germination - lovely summer color

Sep 10, 2022

I had never grown these before so out of experimentation I set the seeds in two pots. One pot was nothing but a hyssop and spider flower seed and the other was a rose I planted the hyssop seeds around. I had no idea what would happen. They got watered every day. The potted rose got full sun and the spiderflower/hyssop combo got half sun/shade. I had great results with both. After germination, I would water once in the morning and that's it. No fertilizer, nothing. Now that these are blooming I will transfer them to one of my beds come Fall.

Not survive winter

Sep 19, 2022

I Winter Sowed these seeds and had lots of plants. I transplanted them into pots and labeled each one. They where 6-10 inches high. Not one survived the winter. I have other plants in the same size pots that did survive. I also have another variety of Hyssop , some in pots and others in the ground. I have no idea why thy didn't survive. I should be done 4-5 and True Hyssop is Zone 3.

Valeria from ME

Owner Response: Hi Valeria, Thanks for taking the time to share your experience. This plant is a perennial in USDA zones 3-11, meaning the plant can survive temperatures down to -40 degrees F. It seems like environmental conditions may have impacted the survival of this plant through the winter. Mulching your perennials will help retain moisture around the roots and prevent upheaval from the soil due to fluctuating freeze/thaw cycles. I hope this helps! Feel free to reach out with any further questions. Thank you for choosing Botanical Interests!
