Cosmos bipinnatus

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.

My first set of 5 seeds under grow lights only yielded 1 successful germination. I tried again and adjusted my heating mat a bit lower (From 75F to 70-72 F) and they performed much better. I got 100% germination the second time around and we shall see how the seedlings develop.

Couldn't get them to germinate. Tried two packages and nothing. Would not buy again.
