Sorry about your dratted voles!
Jill, that is really great to know about the untended greigii tulips returning for many years. Just what I am looking for. The large tulip Casa Grande sounds really interesting to me. I have been looking on the interent trying to find a better selection of greigii tulips than what Scheepers has. They are not that easy to find. I do want those ones I mentioned which I will get a Scheepers but am still looking for more varieties.
