It can be grown from the seeds found in the fruit pretty easily. Seeds are more reliable than transplants in my experience. I have done both and would not bother with transplants again. You may wish to look for fruit in an Asian grocery or Latin American grocery store that focuses on Central American cultures. Or, you could simply do a Net search for "seeds" and "monstera deliciosa".

BTW, if you are in MD, this plant will not survive outside unless you take MUCH care to protect from frost. It runs a long way and is wide for a greenhouse unless the greenhouse is big.
