About Common milkweed
Asclepias syriaca, commonly known as "Common Milkweed" or "Virginia-silk", is a robust perennial herbaceous plant native to North America. It is characterized by its large, oval leaves and globular clusters of purple-pink flowers, highly attractive to pollinators. It is ideal for pollinator gardens, naturalized meadows, and roadside plantings where a rustic look and vital support for monarch butterflies are desired.
Native range
Eastern North America
Care tips
It prefers full sun exposure and tolerates a wide range of soils, though it prefers well-drained, not overly rich ones. It is a very drought-tolerant plant once established, so watering should be moderate, avoiding waterlogging. A common mistake is planting it in very small spaces, as it can spread vigorously by rhizomes and seeds. It does not require regular fertilization.
