Milkweed Seeds - Flower Plant for Home Gardens

Milkweed refers to a group of herbaceous perennial plants in the Asclepias genus, widely adapted to warm and temperate climates. These plants develop upright stems with narrow to broad leaves and clusters of small flowers. Milkweed grows well in full sunlight and prefers well-drained soils, establishing reliably in open garden areas, meadows, and naturalized landscapes. Many species require a period of cold stratification to support germination, mimicking natural seasonal cycles. Once established, milkweed is relatively low maintenance and can tolerate moderate drought conditions.
