Martagon lily is a rare species with small, turk's cap flowers in a beautiful, deep shade of magenta. They are slow growing from seed, but worth the wait. They thrive in partial shade.
I grew my martagon lilies from seed when I was a beginning gardener many years ago. When they failed to sprout in the pots, I simply planted the soil plugs outside, and I was surprised a few years later to find them blooming in the garden. Of course, there are better ways to grow them. For detailed sowing instructions, I recommend this web page.
Hardy in zones 4-9.
