New to me this year, grown from seeds from Prairie Moon Nursery 

This species is one of the largest for a prairie setting, with huge leaves and bloom stems that can extend above other tallgrass prairie species, like Big Bluestem. They are slow to mature, drought resistant once established and not easy to move because of the mass of their root system and overall size. A striking, long-term addition to an ecosystem, they should be placed with the same type of attention to their mature size as shrubs or small trees. 

Please check out the Prairie Moon listing at the link above for more details.

I'm in the process of adding species that I expect to offer this spring to the listings since they are starting to germinate and I'm starting to get an idea of which will be available in abundant quantities.

Since the list is much longer this year I've added several categories to help narrow down your options based on a variety of criteria.
