Overview
- Appearance
- Aegopodium podagraria is a creeping, herbaceous perennial that can grow to be 15.7-39.4 in. (40 cm-1 m) tall.
- Foliage
- The basal and lower leaves have long petioles. There are usually 9 leaflets per lower leaf, although this can vary. Each leaflet is ovate with an acute or acuminate apex. The bases of these leaflets can be rounded or cordate. The lower leaflets are 1-3 in. (3-8 cm) long and have a serrate margin. The upper leaflets are similar to the lower leaflets, but are smaller and ternate in their arrangement, and have shorter petioles.
- Flowers
- The white flowers are arranged in umbels that are 2.25-4.75 in. (6-12 cm) in diameter. Each umbel is borne on a long peduncle, and has 15-25 rays that are about 1 in. (2.5 cm) or more in length. The flowers of Aegopodium podagraria appear in June.
- Fruit
- The brown fruits oblong-ovoid, laterally flattened and 0.12-0.16 in. (3-4 mm) long.
- Ecological Threat
- Digging up this plant can often be counterproductive as fragmentation of the root system stimulates reproduction via the stolons. The non-variagated form is particularly aggressive.
