Here in California the Monarch Butterfly population is decreasing. They live on milkweed, and to help the butterflies, people plant the milkweed in their gardens. I have several plants, donated and self-propagated, in my side patio container garden. The Monarchs do come around, too, and often they flit in pairs. Perhaps we will find caterpillars in the future. This milkweed is sending forth its seeds, scattering on the breeze.
