Hello,
I have a Nerium Oleander with white plants. I was told by the shop where I bought it from that this plant should be kept outdoors and that I should put it in a pot that should have at least 15 gallon capacity. Is this correct? Also recently I read that Oleanders are toxic and die in winter. I live in the Bay Area and right now it is starting to get cold and the flowers are dying. Can I leave it outside in the winter?
