Dear PBS Friends, I have grown many tulips over the years, but find the large ‘Dutch Hybrids’ are mostly deer food (and other critters, too). A few species can somehow avoid being eaten and even fewer have weedy tendencies. I have grown very fond of Tulipa sylvestris which can make a sod of foliage in shade, but produce nice yellow flowers in sunnier spots. It is stoloniferous like T. whittallii which also runs widely with a few rusty orange flowers. I am wondering if anyone has similar experience with Tulips that are stoloniferous and run about the garden. I clearly NEED MORE of these and am open to suggestions. I have tried T. sprengeri repeatedly after hearing of its weedy self seeding tendencies, but it has had no willingness to run amok in my garden conditions. There are few others which seem long lasting and form clumps , but without the aggressiveness i am looking for in my harsh climate. Appreciate your naming tulip “thugs" that I might actually be able to grow here. Thanks Jim W. James Waddick 8871 NW Brostrom Rd Kansas City, MO 64152-2711 USA Phone 816-746-1949
