Besides germinating 100% and being very pretty, these are amazing growers, some standing over 5 feet tall! They bloom profusely and are so beautiful in bouquets. Lovely flower!

How pretty are the flowers, very unique shape! Not that great on germination which is a surprise with Cosmos, but the plants made up for that in size. Collected good amount of seeds of these.

I had to buy these a second time because they were, by far, the best Cosmos blend I've ever had! Of the different seed companies I've utilized over the last 10 years, Botanical Interests seems to have the highest germination rate and generally hardier plants!

I had no idea this flower could be so big! They were at least 4ft high and flowered late summer through to snow fall, so many compliments!
