Buchanan's in the Heights. Most nurseries don't spray them, but they come to them sprayed. Buchanan's sets them aside for a couple of weeks, until the spray has dissipated. Joshua's Native Plants, also in the Heights, is another good source, and they're cheaper.

You can grow more from cuttings, too.

Houston Garden Center usually has them in 8" or 10" pots for less than other nurseries sell the 6" pots, but i don't know if they have them right now. But wherever you find them, you can keep them away from the butterflies for 2 to 3 weeks and they'll be safe.

I haven't had any monarchs for weeks snow, but they should be showing up within a month or so. Do you have some in your butterfly house?

I have a only couple of tiny caterpillars right now on the milkweed in my garden, so am good for now.

Hope to get 8-10 potted plants to put in the butterfly house so that I can rescue a lot of caterpillars out of my garden again this year.

Thanks for the info about sprayed plants being okay after letting them sit for a few weeks. I'll keep a watch out at Houston Garden Center and pick some up soon.
