Jacob, I wondered if they would return here, as we had extreme cold (for our area) last winter. But as soon as the vines began to grow, there were the little clusters of eggs clinging to the tips of new growth. I think these are some of most interesting cats to raise. They line up together when tiny and feed on the leaf, constantly eating it seems. As they get larger, If you stand close to them, you can hear a loud clicking sound emitted when they eat. Sounds like teeth clicking! You can 'hear' this clicking sound on the video linked below. Do you mean too cold for the vines or for the butterflies?

I just yank or cut the tops off and feed it to my chickens, they love it. I like the fact that it comes back so fast so I always have a handful or bucket full to toss in their cage. They get nice greens to eat all year long, you should hear them cackle with excitement as I walk up to them with handfuls. It doesn't seem to bother any plant I have growing in the pot so the pot is serving a dual purpose. I've had to keep the chickens caged up lately because a hawk has killed a few of my free ranging chickens. Lou

Here's one of our favorites made with purple plums. The recipe is very forgiving, but if you're canning you must keep the vinegar in it. It also works to pit plums and freeze to make later in winter. Works fine with frozen jalapenos, too. Depending on your heat tolerance you can make it more spicy using hotter peppers. As our children grew their taste for spicy increased, so we made it hotter in later years; however, we don't prefer it that hot. This is the original recipe with just a hint of spice & not a hot sauce. Asian Plum Sauce Combine: 2 cups brown sugar 1 cup white sugar 1 cup apple cider vinegar 3/4 cup finely chopped onion 2 T. mustard seeds 2 T. green chili peppers, finely chopped 1 T. sea salt 1-2 cloves garlic, minced 1-2 pieces ginger root, 1/4" x 1" Add and bring to boil: 10 cups prepared plums (washed, pitted, chopped) Boil gently for 1 - 1 3/4 hours. Puree with a handheld blender. Can or freeze. Can with 1/4" head space & process for 20 minutes. Makes 4 pints. Enjoy it on meats, in stir fry and as a dipping sauce for egg rolls. Corrine

I never in a million years would have imagined people would be so generous. I have some going out in spring (I wont forget about your either Brad), and by this time next year I too will be able to make it rain little Hoya babies on people, and I can't wait!!! :D I think one of the best parts of this hobby is being able to share! A friend in town is a houseplant person too, I am slowly converting her into a Hoya Head with cuttings and its great.
