- Description
-
Bog Spurge is an upright herbaceous perennial in the spurge family (Euphorbiaceae) that has chartreuse leaves and flowers. It typically grows 2 to 3 feet tall,but sometimes you will find it taller. It is native to marshlands in Europe and Western Asia. The specific epithet, palustris, means marsh-loving.
Plant in full to partial shade in well-drained, moist to wet soils. It will adapt to various soil types. It tolerates browsing by deer and rabbits and tolerates drought, wet soils, and shallow-rocky soils. Plants may sometimes show some stress in hot and humid summers. Bog spurge can be propagated by seeds, stem cuttings, or division in the early spring.
The foliage is a medium green, but transitions to yellow or orange in the fall. The flowers are clusters of greenish-yellow blooms that appear in the late spring and early summer.
Mass plant it in a border or let it naturalize in a cottage, woodland, or rain garden.
Insects, Diseases and Other Plant Problems: Bog spurge has no serious insect or disease problems. Monitor for aphids, mealybugs, nematodes and spider mites.
As with all euphorbias, bog spurge exudes a milky sap from the stems and leaves that can be toxic. Monitor in the presence of children or pets. Some people experience skin rashes or eye irritation from contact with the toxic sticky plant sap of euphorbias. Wear protective gloves when handling this plant.
