How cold hardy are weeping Lantana?
I have two weeping Lavender Lantana in hanging baskets (the plants are 5' long) and they are still thriving despite having several gentle frosts already. The days have been in the 50's. They are somewhat protected because they hang at the edge of an outdoor porch.
I plan to trim back the plants and bring them in for the winter. I don't want to do that prematurely if they can handle the cold outside, but I don't want to kill them either. How cold can they tolerate it? Any advice on when to bring them indoors?
