I planted a small snail vine in the spring. It was a little slow getting started but once established, it has taken off. The beautiful vine is growing up a lattice and I am training it to offer some much needed privacy. My question is DOES THIS PLANT BECOME DORMANT in winter. I keep seeing postings about overwintering. I am new to the vine gardens and would like to see this plant thrive. If you know the best way to take care of this plant or if there is anything special I should do\consider during the colder months. I live in central California so it really doesnt get THAT cold! Also, is this in the BEAN family?
