starting natives from seed: how long to bloom
I have had good luck with Agastaches from seed, most even bloomed the first year, especially if planted the previous November, and also Achillea and Aquilegia, but the milkweeds I tried either didn't sprout or I planted them out the first year and they didn't make it through the winter.
Plants I'm considering this year are several Solidago- goldenrods, and Stylophorum. I'd like them to bloom the first year but would be OK to wait until the second year but would like to plant them out and have them make it through the first winter at least. Has anyone grown these from seed? I am tempted to buy at least a few as plants instead since I am counting on these to have a presence in some areas where I have trouble with grass weeds to keep the grasses from growing. Some of the goldenrods form rhizomes and spread well, which I am looking for in some areas. Stylophorum photos impress me as making a nice solid clump that should help with weeds as well.
