I'll be looking for the Species Tulip humilis violacea with the dark center up here. Love it!
My grandmother had a couple species tulips (I think T. tarda was one of them) massed in a bed for decades before she let lily of the valley take over. They weren't as flashy as that pink one, but I have a soft spot for them. I'd love to have masses of different species tulips and crocus one day. I added some crocus, muscari, hyacinth, tulips, and fritillaria to my garden last fall, but just small quantities--nothing like you Rita. I think I'd need to work out for a year in preparation for that kind of planting!
