|I potted up my varigated and regular vinca vines and brought them inside. They don't look so hot - can you treat them as houseplants? Do you need to cut them back?|
|I'm going to assume since you brought them inside that they are not the perennial, evergreen variety of Vinca minor, but rather the V. major or V. rosea. The latter two are treated like annuals in our northern climate. Usually they are used for window boxes and will stand more sun that V. minor.
The plants may not flourish indoors, but rather just stay alive long enough to carry them through until next spring. Place them in a spot where they receive good light and at least some sun. Theyshould be kept moist but NOT soggy! Keep a close eye out for insects--especially spider mites (look for fine webbing on leaves). And yes, I'd cut them back to 6 to 8 inches.
