Herbs Weed profiles & Native alternatives
I’M A WEED
Rosette-forming, perennial or annual herb to 30 cm high. Leaves mostly basal, lance-shaped, 5-25 cm long, 2-6 cm wide, green and slightly hairy above, white woolly below, and toothed margins.
Erect Flower stems arise from the centre of the rosette, 8-25 cm long. Yellow daisy flowers have 15-20 yellow petals 1.2-2.5 cm long, radiating from a black centre, from August to October. Very common weed of cultivation and disturbed land, especially on poorer soils.
Coastal Beach Daisy
Annual or perennial, creeping, mat-forming herb, to 20 cm high, only found on beaches. Leaves are large, heart-shaped with short stalks, slightly succulent with a dense covering of white hairs. Margins are smooth
or slightly toothed. The yellow daisy flower heads 3 cm diameter on short, stout, curving stems and often
overtopped by the large leaves. The bright yellow petals are widely spaced around a greenish yellow centre.
Threat / Problem
• Form very dense mats over the soil surface, preventing native species becoming established. Readily invade disturbed sandy areas.
• New plants grow from prolific seed spread by soil movement, wind and water. Also grow from runners spread from garden waste dumping.
• Hand pull small plants. Spot spray late winter whilst actively growing. Resistant to some herbicides.
GROW ME INSTEAD
Ascending or prostrate shrub to l m high. Deep green leaves are round to elliptic, 2-4 cm long by 1-2 cm wide, with toothed edges. Sparse, fan-shaped, yellow flowers 0.8-1.8 cm long, form in winter and spring.
Fruit is cylindrical, pale brown, 0.8-1 cm long. Common in woodland, mallee and coastal heath.
OR GROW ME
Perennial herb 0.2-1 m high with very branched spreading stems. Leaves are distinctively blunt tipped and Y-shaped, each one consisting of two fleshy, bright green, thin leaflets with stalks at the base. Flowers have four spreading, bright yellow, rounded petals, to 1 cm long, borne singly in the leaf axils (where the stem meets the leaf) from June to December. Fruit is a drooping, 4-angled green capsule 1-1.2 cm long, almost triangular and cut off bluntly at the tip, where there is a small point. Each of the four cells have one or two brown seeds.
Common on coastal cliffs, between rocks, with inland forms also on red and brown soils.
