You'll find lots of Lady Slippers (ie, Cyps) in the NH woods! That's the real joy of living where you do. They're protected, so don't consider digging any.
Also know that they likely won't take to cultivation, so they're actually safer in the wild.
But if that is a Cyp. acaule, you're a lucky duck!!! Congrats! Please post pics - you'll drive Tim-O mad with envy!
