Sounds like an ideal slope for tulips, Caroline! Some of the species tulips we tried naturalizing here refused to bloom, probably because our summers are too cool for them and while I don't remember all their names, I do know that many survived for many years, even after the deer became a problem. Tarda I do remember and that is one strong bulb, capable of surviving, spreading and blooming for many years totally without care.
I tried Praestans 'Shogun' for the first time last year and really loved the very warm yellow-orange color. It produces surprisingly many good sized flowers from its rather small bulbs!
