Gardeners' Notes:

These are great plants for attracting the monarch butterfly. She will lay her eggs on it and the caterpillars will eat them up. Please let them! Aphids are normal on this milkweed, so do not worry about them. Whatever you do, do not spray poisons on them. This will harm the butterflies and that would be wrong.

This plant serves as both a nectar source for Monarch butterflies and a food source for their caterpillers. It can grow in sandy, unenriched soil and can become somewhat invasive as the seeds are released. I just collected some seeds and will try to direct its spread! Mine grows in direct sun here in z9b and I haven't found that it needs constantly moist soil although it does like to be watered regularly.
