An out-of-this-world color of cosmos! This fairly new, yellow beauty (xantho means "yellow" in Greek) won the Fleuroselect Novelty, and Gold Medal awards in 2016. Not only is the color unique, the plants are early to flower, well-branched, and shorter, making them an excellent choice for containers or borders. Cosmos are drought tolerant, practically care free, attract pollinators, and make a nice addition to a cut-flower bouquet.

I previously left a poor review because I couldn’t get these seeds to germinate, but I’m happy to say I gave them another try this year and had great results! I planted seven plants in the pot shown in my photos and they are absolutely beautiful. Everyone who sees them compliments the flowers! They attract lots of butterflies and bumble bees and they’ve been very easy to care for. I’m so glad I tried them again and would definitely recommend them.

Which best describes you as a gardener? Intermediate - Erika F.Verified BuyerRated 1 out of 5 starsAug 5, 2026Only 2 out of 25 seeds germinated
I was very disappointed with the germination rate from this packet. I planted all 25 seeds, and only 2 germinated. The two that sprouted are still just seedlings, so I can’t review the flowers yet, but a germination rate of only 8% is extremely poor.

- taylorRated 1 out of 5 starsAug 2, 2026no success for me
i have ordered and also purchased in store many botanical interest seeds with much success, however like many others state these were just hard to grow… first round in spring i didnt see much germination but maybe the nights were a little too cold for their liking (7b grower) so a little further on i planted more and got a few more sprouts but in the long run eventually all of them ended up not making it. they seem super finicky in comparison to other cosmos (for reference i have 3 other kinds thriving that i planted at the same time) bummed, because these look gorgeous!

- BeckyVerified BuyerRated 2 out of 5 starsJul 30, 2026Not worth it
I planted these cosmos hoping to use them for my wedding, but they took forever to flower, and the flowers are so small and die within a day even with ideal conditions and daily watering. My other cosmo varieties are doing great. Absolutely not worth the garden space or effort.
