Hardy spurges (Euphorbia) typically don’t take kindly to soggy soil, but wet feet are just fine as far as marsh spurge (E. palustris) is concerned. Imagine a giant version of cushion spurge (E. polychroma): a mounded form, sort-of-oblong green leaves, clusters of showy yellow “flowers”, and fall color in shades of orange, yellow, and red. Marsh spurge, also known as swamp spurge, gets significantly larger than cushion spurge, though–in the range of 3 to 4 feet tall and wide–and flowers in late spring to early summer. As with other spurges, its stems and leaves have a milky sap that can irritate skin and eyes, so be careful when working around the plants. Full sun to light shade (particularly in warmer areas); moist to wet soil. Perennial; Zones 5 to 9. Will self-sow if not deadheaded.
Harvested in early July 2022. At least 10 seeds.
