My columbines already in flowerbed from last few year's growth are bushy out beautifully..I've been thinking about direct sowing some seeds that I had collected last summer from them, but since I didn't keep them separated by color, they'll have to be mixed colors. Didn't know about gathering seeds then or wintersowing. Should I just scatter on ground or work up soil and lightly cover the seeds? I thought when you wintersown them, it says not to cover.Would that apply to direct sowing too?
