What are the pros? Colors, Height, Consistency
What are the cons? None
I tried growing these because of a wedding request for the "deep pink" cosmos, which otherwise meant growing the usual suspect and picking the few dark flowers that showed up in a timely manner. I start all seeds in a greenhouse and I let these get pretty tall before it was warm enough to plant them in the garden. Some were already blooming and they were pretty leggy. I pruned them back and staked, and though they languished a bit at first, as it got warmer, they flourished. I'm delighted with the color which does start off deep reddish burgundy and fades to an old rose color, eventually much lighter than the photo they show for this flower. They have bright yellow centers. I like that these cosmos stay at about 24 inches tall as promised. I wish I could post a photo, but that's not an option here. I live in Zone 8 in the Coast Range of Oregon and these cosmos get a LOT of sun in our garden and reside in a raised bed that gets regular watering.
