beautiful blue cascading flowers

5 out of 5 stars Jul 28, 2019
I had great germination with these seeds. The tiny blue flowers are very pretty; and they are on cascading stems. I have had no trouble growing these.

I've grown lobelia from seed before, but these were disappointing. Although they germinated well, the seedlings shriveled before reaching half an inch in height, even with careful watering, sunlight, and temperature monitoring. (The replanted seedlings did the same thing.) Not sure what went wrong. I was looking forwarding to seeing the beautiful colors in this seed blend.

Owner Response: Thank you for sharing your experience. Once germinated the success of the plant is environmental. It sounds like the plants may have been too wet or succumbed to a fungal disease called damping off. Please feel free to contact us when you have questions, we are here to help!

Still waiting for flowers

All seedlings sprouted so far. Waiting for the beautiful flowers.

Owner Response: Hi Teresa, We are glad your lobelia germinated well. Adding a fertilizer that is weighted towards phosphorus can help encourage flowering. Happy growing!

A new garden favorite

I have enjoyed your Trailing Lobelia so much. A great addition to my garden. They flourish in both sun and shade. They love wet soil and attract the tiniest pollinators. Gorgeous trailing flowers! They've been producing flowers for 6 months now with no sign of letting up. :)

Excited to Grow

5 out of 5 stars Apr 13, 2021
I'm excited to grow these pretty trailing flowers! Hoping to be able to have a gorgeous flower basket filled with these by June! I was confused about planting. How many seeds do I grow in one spot? I reused a 6 pot tray, planting 15-20 seeds in one pot. Did I do that right? Do they need full sun as well?
Bettina from CA
Owner Response: Hello Bettina, thank you for taking the time to leave a review. You did that correct! Plating 12-20 seeds per group is recommended for this variety. When reusing containers we always recommend giving it a thorough cleaning with a diluted bleach solution to eliminate problems in the future. Seeds need around 14 hours of light per day. Once they have established, Lobelia can handle full sun to part shade. Happy growing!

Pretty, but only one color

Germination went well, planted it out in hanging baskets, planters, and a couple of the raised beds. I love the trailing habit and they've been blooming for a couple weeks now, but these flowers are only one color, a periwinkle blue. What a disappointment.

I started these in the greenhouse late winter zone 8b. I think every seed started! I planted them everyplace in my flower garden, the hanging baskets, and planters. Most of them bloomed blue, a couple in the magenta color range. They are trailing about 15 inches so far, and they are blooming non stop as of summer solstice. The most success I am having with seed starting!

Prolifically blooming lobelia!

This variety of trailing Lobelia was started indoors well in advance to transplanting outdoors into window boxes. They came up full, grew and bloomed all summer long! Such a joy!

This is doing beautifully in a northern exposure. Covered it because of a hard freeze and it lived.

My seeds didn't germinate. I started the first batch at the end of January and nothing happened after 6 weeks. I thought it was the soil since it was in my garage since last year. So I bought new soil and started the second batch at the middle of March. It's been a month and nothing has happened. I researched as much as I could: used a spray bottle, soil and room temp was right, under lights during the day, dark at night. I don't know what else could have been done differently but with 2 batches not growing, it's disappointing. But I will say that out of 2 years of buying seeds from here, these are the only ones that didn't germinate. I'll still be a returning customer.
Diana from GA
Owner Response: Hi Diana, We are sorry you had issues germinating these seeds. A customer service agent will be contacting you by email to help. The only trick to these, you likely saw on the seeds packet, which is that seeds need to be surface sown as light aids germination. It helps to place a humidity dome or plastic food wrap over the sown media to make sure the seeds do not dry out (they are more susceptible when surface sown). Seeds, however, do not need grow lights until they germinate. When germination is aided by light, ambient light in a room is enough. Rest assured, our seeds are tested regularly by a third-party laboratory to ensure germination rates meet federal and our own standards.

Mine are all blue. Last year I bought the mixed color seeds from another supplier and they were so beautiful. The blue is ok but I really wanted the gorgeous mix of all the colors. Wouldn't buy again.
laura from CO
Owner Response: Hi Laura, Thank you for taking the time to share your experience. We are sorry that these seeds did not produce enough color variation. We surely hope that you try again as these are a customer favorite!
