I have Asiatic "Buff Pixie" , "Crimson Pixie" and oriental "Dreamcatcher". When the bulbs fell off there is a stem like thing there that I thought was a new stalk or something but they hav'nt grown or done anything. Should I pinch these off. They are coming directly out of the original stalks (scapes??) that held the first blooms. I am a complete newbie-please help!!
