I say the same, I have grown H. heterodoxa x minor, H. nutans, H. heterodoxa x nutans, and H. neblinae, unfortunately I've traded them all away (newbie mistake, trading plants you dont have extras of) anyways I had great success with them in Highland conditions, high humidity is a must and cooler nights help it to pitcher faster, coem to think of it, I am getting my first helis since the greenhouse this friday/saturday, H. tatie var. tatie, and H. heterodoxa, I bought them for a science expirement, anyone ever tried leaf pullings of Heliamphora, I figured it should work since they're in the sarraceniacea family too
