| British elecampane - Inula britannica L. |
| Weed Identification in Nurseries and Landscapes > British elecampane |
Life cycle: Aggressive, invasive perennial.
Flowers and fruit: Numerous yellow, 0.75- to 1.5-inch-wide flower heads form on a single plant, each head looking like a small sunflower. The area just below each flower head is encircled by several small, green bracts. The seed is enclosed in a single-seeded, small, light brown, wind-disseminated fruit.
Stems: Erect stems with coarse, white hairs arise from a basal rosette to flower, up to 30 inches tall.
Leaves: Alternate, lance-shaped leaves initially develop from a basal rosette. Leaves have pointed tips, arrowhead- to earlobe-shaped bases and finely toothed margins. Leaf bases are stalkless to clasping the stem. The lower leaf surface is densely covered with coarse, white hairs; the upper surface is only slightly hairy.
Reproduction: Seeds and creeping roots. |
