Aegopodium podagraria Seeds | Ground Elder
LATIN NAME: Aegopodium podagraria
COMMON NAME: Ground Elder, Bishop’s Weed
Plant Profile
Ground elder is a rhizomatous perennial of the carrot family, native to Europe and western Asia and carried around the world as a garden plant, a pot herb and a weed. It grows thirty to a hundred centimetres tall, with hollow grooved stems, divided leaves with toothed leaflets, and flat umbels of tiny white flowers in early summer.
The rhizomes are white, brittle and deeply buried, and a fragment the size of a fingernail can regenerate a new plant. In shade it forms a dense, weed-proof carpet; in a border it becomes the weed, and its ability to run under paving and through hedge roots makes it a long-term adversary.
Science & Biotechnology
The species is a classic subject in weed ecology. Research has measured how rhizome fragments of different sizes survive cultivation and how far the plant spreads from a single introduction, which is why garden advice stresses repeated digging rather than a single attack.
The plant is also studied for its flavonoid and polyacetylene content, and it appears in surveys of urban biodiversity because it thrives in neglected corners. Its ability to move resources between connected rhizome segments has been used as an example of clonal integration, where one part of the colony feeds another through shared underground tissue.
Uses & Benefits
Young leaves picked before flowering have a mild, parsley-and-celery flavour and were once cooked as a spring vegetable, a use that foragers still practise. The plant was grown as a potherb and as a remedy for gout, which survives in the name goutweed.
In modern gardens its main role is as ground cover in dry shade under trees, where little else will grow, and the variegated form is a recognised ornamental. It is also a useful nectar source for hoverflies and small bees in early summer, and its dense mat suppresses weeds that would otherwise take the same ground.
In shade it will cover a dry bank within two seasons and hold the soil through winter.
Growing from Seed
Seed is often sterile in the common form and the plant spreads mainly by rhizome, but fresh seed does germinate. Sow on the surface of a moist mix, press in, and keep at 15-18C in shade.
If you want the plant for eating or for ground cover, start it in a large container sunk into the ground, or in a bottomless bucket, because once it is loose in a border it is very hard to remove. Divide rhizomes in spring for a faster start, and pull any seedling that appears outside the boundary at once. Water only if the compost dries out completely in summer, and never let the pot stand in a saucer.
Our Take
Grow it in a bucket or not at all, unless you want a garden full of it. Where its spread can be contained, it is a useful ground cover and a passable spring vegetable.
