Description
Blue Cardinal Flower is actually quite different in growth from its wildflower counterpart. It is a tougher, heftier plant with somewhat coarse, larger leaves, and the flowers appear in the leaf axils, unlike its elegant cousins red flowers that are in leaf-free flower spikes, held high above the plant. But the blue flowers are lovely and plentiful. Best of all, this plant is not as picky as to growing conditions. It is perfectly happy in any perennial garden with half sun to part shade. And it is simple to propagate. Let some of the flower heads go to seed in the fall, and you'll have a dozen new plants coming up next spring.
Blue cardinal flower makes a great background for smaller wildflowers, since several together form a wonderful screen-like clump of towering plants with blue flowers for a long period.
Oh, and the name. The botanical species name, syphilitica, comes from the Native American belief that this plant was a cure for syphillis.

Great Blue is truly GREAT.
"This plant truly surprised me when it seeded itself prolifically. I planted 3 and a 2 were nibbled by critters but to my surprise and delight, the following fall there were dozens popping up. A gorgeous native that I am so glad to have around."
Spectular
"Planted this in a bog. It is thriving and beautiful!!!!"
💖🪻:woman-lifting-weights:Defied the Odds & Survived my Neglect 💪🪻💖
"Anything that makes it in my garden is a sur👏vi👏vor👏, and Great Blue Lobelia has defied the odds despite my lack of best efforts. I panted it in autumn last year, and it's blooming late-summer/early-autumn this year. It survived a heat wave, sporadic watering 😬, and the overgrowth and territory infiltration of neighboring sage and Chinese lanterns. I planted in half-sun/half-shade, on both sides of my flower bed, in what I wrongly presumed would be "blank" space in one case. One side of the bed gets a little more sun than the other, and it's evident that Notorious GBL prefers it. I'd go so far to say not to plant it in shade, as AMI's plant information suggests you can do, and opt for part to full sun. That being said, the one with more shade did alright. It produced one flowering stock, which looks like it has more flower heads coming in, but at a much slower rate than the other. All in all, great plant, and I'll likely plant more elsewhere in my garden in the future."
Love It
"We have hummingbirds, and I have a pollinator garden. They love it! Beautiful plants"
Nope
"Planted them and 2 came back the next year. So then I planted more. Only one came back this year. Very disappointed"
Love this flower but. . .
"I had these last year in a shade garden, they did wonderfully. I propagated some and bought more for this spring. It is unusually hot this summer and i don't see that getting any better. Even in 80% shade, these plants are not holding up even with regular watering. I have lost several and the ones i have left are not doing well. The heat is killing them off one by one. It is a beautiful plant and would do great in a cooler climate. I am in NC, for reference."
Great Blue Lobelia
"The plant arrived well-packaged but was rather small-sized. It took over 6 weeks to acclimate itself to the Northern Alabama climate and soil. . . which is NOT altogether unusual for plants not purchased from a local source. This lobelia is now growing well and should be producing flowers within the next 3-4 weeks."
Cute but really small.
"I planted these in a small garden on the side of the house to attract bees and butterflies. They sprouted and bloomed quickly but at only 8" tall they seem kind of lost. Guess I will have to transplant next year!"
Love it, growing great, ready flower.
"I'm hopeful that it will flower this, the first year"
Cant wait to bloom!
"growing w/ blueberry plants & golden hops (not eating the lobelia) It is too new to tell, but I would think a couple of seasons the plant will be thriving"
