Green Milkweed

Asclepias viridis

Milkweed, Green Antelope Horn Milkweed

About This Plant

Full sun or part shade. Perennial, with thick green foliage in excess of 24 inches tall and wide. This is one of the taller milkweeds native to San Antonio. A large umbel of intricate flowers is produced at or near the end of each stem. Much like Antelope Horn Milkweed, the seed pods or follicles resemble antelope horns as they mature. Milkweeds are the only food source for monarch butterfly caterpillars.

Origins: From Nebraska to Texas, east to Florida

Maintenance

None, beyond the care needed to establish. Aphids are likely to infest any milkweed, but they aren’t really a problem. They can be squished by hand or sprayed off with soapy water. Treating aphids will (obviously) wipe out the monarch caterpillars too.

Great Milkweed for a rain garden or deeper soils.
