Havoc - they're growing outside and the pistils are actually white (hence the name edelweiss). And, actually, I'm am a bit unsure of when to harvest. I'm thinking with-in the next few weeks. (weather is changing here, starting to get chilly and wet)
Roadblock - I used Miraclegro worked like a miracle. Will you be able to plant them outside or will you keep them inside? These plants have a huge root ball, almost as large as the plant itself, so, if you are going to keep them inside they will need ALOT of fertilizer, fairly large pots and grow lamps. Your 3-way living room lamp will not be sufficiant.
