Also known as: Wand milkweed, Green-flower milkweed
Green comet milkweed (*Asclepias viridiflora*) is named after Asclepius, the Greek god of medicine, but is native to the plains and prairies of the United States. This species has deep roots that help it withstand fire and drought. The flowers are sweet-smelling and produce generous amounts of nectar. Female monarch butterflies lay their eggs on green comet milkweed, as the larvae eat only milkweed.

Water:
Originating from moderate moisture regions, green comet milkweed thrives under balanced conditions. It benefits from weekly watering, showing resilience to fluctuations. Adapted to seasonal rainfall, green comet milkweed is ideal for temperate climates, aligning well with natural growing seasons in outdoor gardens.
Fertilize:
For optimal growth and blooms in green comet milkweed, use a balanced fertilizer at half-strength every four weeks in the growing season, less in winter. Over-fertilization can harm green comet milkweed, so adhere to recommendations. Slow-release formulas are recommended for steady nutrient delivery, enhancing vitality for a stunning garden display.
