|Asclepia linaria is a tough milkweed that performs best with very good drainage. This species can produce abundant stems with dense, evergreen foliage. Of the 32 milkweed species in Arizona this one contains the highest levels of cardiac glycosides, which are the chemicals that deter insect grazing on milkweed plant. Although Monarch and Queen caterpillars can tolerate these chemicals to a large degree, the high concentrations in this plant make it less effective as a larval food source for these butterflies, though still a very good nectar source.
