Terrestrials for pennsylvania growing?

[Orchid126]

I live in NJ near Trenton and I have had a bed of bletillas, all blue and all white, on the northwest side of my house for the last six years. They don't require any care other than piling leaves on them in the fall to protect them somewhat over the winter. The bed keeps growing bigger and bigger. They bloom in early spring.
