I’m growing a few flowers that I would not recommend, or at least I don’t want to grow them again.
This is Cosmos bipinnatus ‘Double Click.’ I was pretty excited to grow it last spring when I ordered the seeds from Thompson and Morgan. I need to remember that Cosmos get mildewy very easy, even in our dry mountain climate. The foliage on these plants is a mess, and the flowers are held in awkward positions. The stems got twisted instead of standing up straight. And they ended up blocking a sprinkler from reaching some daylilies, and it wasn’t worth killing a few daylilies for these!
This is a perennial I’ve had for at least four years. It’s Anthemis tinctoria ‘Kelwayi’ and it’s a major thug. It spreads everywhere in my yard (and neighbor’s yards). It only looks good in June, when it first flowers, and after that it’s a messy mass of seed-producing ick. I think next year, I’ll tear them all out and begin eradication!
Actually, I had another plant like this that I recently placed on the seek-and-destroy list: Achillea. Can’t remember the exact variety, but it was supposed to be a mixture of whites, pinks and reds, I think. Turned out to be a major, major weed. I’m finding seedlings in the front flowerbed and yanking them whenever I can. I think next year might be the year to show Anthemis its doom as well! :-|
