    I’m confused about Columbine. According to the how-to, you direct sow in fall, but you say August? And it takes 30-90 days to germinate?! So does it bloom in the fall or is the planting for spring bloom?

    Hi Rosanna – Columbine is one of the perennials that benefits from its seeds overwintering. It will germinate very early the following spring. If you’ve seen columbine in the garden before, their seed pods develop and split by around the middle of July. The seeds sit dormant until they have gone through the cold of winter. If you plant the seeds in early spring, they will still germinate, but you will probably not get flowers the first year.
