Milkweed: A Field Guide
Planting milkweed can open up a whole new world. Not only does it do edible double-duty on both dinner plate and cocktail coupe, but it’s a host plant to the threatened monarch butterfly.
With over 140 known species of Asclepias, only 30 nurture the monarchs. They include A. tuberosa (“orange milkweed”), the sweetly fragrant, pink A. syriaca (“common milkweed”) and A. californica (“California milkweed”), with its fuzzy stalks and leaves. Avoid the similar genus Cynanchum (“swallow-worts”), which fool monarchs into laying eggs on them that will never develop. Seek out a variety native to your area. Milkweed is a quick and aggressive grower.
