The white/yellow is Tulipa tarda. I can't remember the other one. It didn't bloom last year so I was surprised to see it this spring. I had planted lots of them....I guess only one survived the squirrels. I'll be looking for it again this fall to plant more. It's spectacular.
Thanks, Wendy, I'll tell the cats just rember that tulips want moist spring and dry summers. The latter can be accomplished by using decidious trees. The tolerance level of the hybrids vary tremendously, but the so-called Darwin hybrids are ptobably the easiest. Like my Aapeldoorn in the pictures.
