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!
