About Swamp Milkweed

Swamp Milkweed is a herbaceous perennial native to North America including Florida, occurring naturally in wet prairies, swamp edges, and moist disturbed sites. It produces clusters of small pink to rose-purple flowers from summer into fall and is a documented host plant for Monarch butterflies. A distinct species from the common Milkweed (Asclepias tuberosa). Starting at $9.95.

Care essentials

Light

Swamp Milkweed performs best in full sun but tolerates part shade in NE Florida. More sun produces heavier flowering and stronger stems; in deep shade it becomes leggy and blooms sparsely.

Water

Prefers consistently moist to wet soil; it is native to wet prairies and swamp margins. In NE Florida sandy soils, water regularly during dry periods — the plant will tolerate brief drought once established but foliage will suffer.

Soil & Fertilizer

Grows well in moist loam or clay; tolerates poorly drained soils. In sandy sites, incorporate organic matter to retain moisture. Fertilize sparingly — average fertility is sufficient; excess nitrogen reduces flowering. Do not disturb deep taproots after establishment.
