Please don't let acidic soil keep you from trying martagons. Here in far northern Michigan our sandy soil is acidic, too, but martagons thrive here. In the garden, I add lime at planting time, but rarely think of it later, and they do fine. Another plus: of all the many lilies I've tried, martagons are the least favorite of the deer. Most lilies are just expensive deer food for us, but not these. They get munched occasionally, but not usually, and never enough to kill the plant. I love their little flowers that look as if they're carved from wax. Some varieties have a lovely fragrance, too.
For many years, I've thrown ripe seed out in our popple (quaking aspen) grove, and we now have martagons blooming there, too. Germination is slow, as the first year the seeds only put down a root, not growing a leaf until the second year. But what the heck, the years are going to pass anyway, you might as well sow lily seed and let them surprise you a few years down the line.
