The listing, Imperial foxglove 50+ mixed colored seeds has ended.
These flowers grow 3'-4' high. I am including lavender, yellow, pink, and red. Mine grow best in full sun, but have some in partial shade in the afternoons that grow just fine also.
They like well drained soil. I.e...They don't like dry soil, but don't like soggy soil either.
They are perennial and self seeding.
I jave foumd that if I allow the flower heads to stay on the plant they seed themselves a lot. So, I jist let the flowers dry on the stalk and drop seeds to drop for new growth.
When planting them, keep that in mind. So, don't bury them too deep. I would place the seeds on open soil, and just cover them with an additional 1/8" of soil then water.
I looked, and I found that they are hearty in zones 4-10.
