Swamp Milkweed

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.

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.

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.
