Leaves of milkweeds are eaten by monarch caterpillars; non-native Mexican is common in nurseries, to encourage migration and reduce local overwintering, which may increase disease; cut back to 6" Nov-Feb. Plant natives when possible. Native A. tuberosa needs good drainage; do not disturb its taproot when transplanting; or try it, A. asperula and A. viridis from seed.
