Answer: You are in zone 7, with an average minimum temperature range of 0 to 10 degrees F. This means that you should plant spring-blooming bulbs by early November in your area. (That's why they're all sold out.) Next spring, you could plant summer blooming bulbs, such as gladiolus and dahlias. If you're interested in bulbs, a good reference is Flowering Bulbs for Dummies by Judy Glattstein and the NGA.
