Well, it finally happened. We got a freeze--the thing that tropical gardeners fear. Needless to say, many of my plants are looking pretty crispy right about now, including my coveted crinum lilies. I had read that they're cold hardy into the 20s, but that doesn't mean that their foliage can't get burned back. Chances are the plant itself is fine and will put out new growth in spring.
I'm guessing the crinums will recover, since this is what typically happens with my Dwarf Cavendish bananas. Each time we have a hard freeze--this time my indoor/outdoor thermometer registered a 29.8 degrees as a low--the leaves get fried. But time after time, the bananas put out new leaves and are back to their perky tropical selves by mid-summer.

Tip: Always wait until after the last freeze before pruning back any freeze-damaged plants. If you prune earlier, you might encourage additional damage if another hard freeze comes along.
