I’ve got to start reading my own stuff more carefully! The mysterious yellow tulips that I forced recently have been identified: They are called Daydream, and if you are looking for a tulip to brighten up your yard or house, this variety would be great. The identity of the tulip was listed in the blog in a post I wrote last fall when we first planted them outdoors. The purple tulips are still unidentified, but they are starting to bloom. They seem to be a smaller, later-blooming variety, but still very pretty.
