I live in Nova Scotia, Canada and our weather is soooo unpredictable. I'd greatly appreciate any info you could pass along. I've noticed a lot of other posts on wedding B.B asking about this same subject. I love tulips too. In fact, they are my favorite flower, and most couples want them for their weddings.
Most Tulips come from Holland and they bloom in spring.
Gardening is not my expertise. All of our flowers are bought at wholesale markets. And, I am unfamiliar with your growing plants in your zone. I would highly suggest calling your local nursery and asking them your questions. I have also provided you with some addresses of places that I know specialize in bulbs.
