Mary Sue mentioned Tulipa praestans in her recent post. This species (in particular the cultivar Fusilier) has been a very good doer in my Maryland garden. It does not spread, and it clumps only slowly, but it persists and blooms annually without being dug for the summer. I've had the cultivars Fusilier and Zwanenburg: they are different enough to make both worth having. Mark and Mary Sue both mentioned Tulipa batalinii. This persists for awhile in the garden but eventually disappears if not dug. Here's another thought about this plant: Mark mentioned that Rix makes this a form of T. maximowiczii (the name is spelled both maximowiczii and maximoviczii in the Rix/Phillips The Bulb Book and in Anna Pavord's The Tulip - how's that for covering your bases?), whereas others make it a form of T. linifolia. It occurred to me that both may be right. What I mean is this: maybe the Tulipa batalinii of horticulture is polyphyletic. TT. linifolia, maximowiczii, montana, wilsoniana all probably have yellow variants and telling them apart in cultivation (i.e. without reference to their populations in nature) would be tricky. Mary Sue's comments about the differing behavior of her stocks of T. batalinii and T. linifolia are intriguing. Spring here is so condensed and fast that I've never noticed such a pronounced difference, but commercial T. linifolia is a bit earlier than commercial T. batalinii. Are they different species or are we just seeing the two ends of a convoluted rope? Tulipa bakeri Lilac Wonder was also mentioned. When I was starting out in tulips, this was not available. What was available was Tulipa saxatilis. Tulipa saxatilis puts up foliage in the fall; the foliage is severely damaged in a typical winter. As a result, I grew this species (by replacing it frequently) for years without ever seeing it flower. Once, some bulbs planted near the house wall produced one small flowering plant - and it was gone almost before I got a good look at it. When Lilac Wonder became available, I was dubious: wasn't it just another saxatilis variant under a new name? Was there any reason to think that it might do better here? Several people have since told me that it does do fairly well in this area. I'm still a doubter, but I do have some plants now. Has anyone else on the east coast had long term success with this outside? Jim Waddick mentioned Tulipa sprengeri. I grew this from seed; it bloomed in four years as I recall. Rather than spreading, it then disappeared.
