It is now ipomoea acuminata. It is illegal to sell in some states. I had to bring one back from California. There are no seeds, it propagates by runners. I keep mine in a huge pot with small drainage holes and several layers of hardware cloth on the bottom to prevent roots from exiting the pot into the soil underneath. It is also much easier to kill if it gets out of control. You can just cut the canes at the pot soil line and dig the roots out of the pot. Love, love, love it. Excessive rain just killed mine last month. Oh darn. Guess I'll need to drive over to San Diego!
