Speedwell Weed Identification.
You can easily identify the Speedwells. Their leaves have an oval shape, and they have numerous small flowers in a range of colours spread out over their stems.
Birds-eye or Creeping Speedwell:
-
Growth habit: This is a prostrate, low growing annual (sometimes it is a short-lived perennial) weed.
-
Leaves: It has broadly ovate, coarsely toothed leaves. These have hairs on their upper and lower surfaces. The leaves are relatively large in comparison to other Speedwells.
-
Flowers: The flowers are a bright sky-blue with a white centre. They are ~8 to 12 mm across and on stalks. This weed has the largest flowers of the four.
- How it spreads: It spreads by stolons and seeds. It grows into thick weed mats and then smothers turf.
-
Habitat: It favours disturbed soils, and lawns.

-
Growth habit: This is a small, upright Winter annual weed, that is usually <15 cm tall. This means that it germinates in the Autumn and flowers in the Spring.
-
Leaves: Field Speedwell has hairy leaves. The lower ones are round/ovate, whilst the upper ones are narrower and clasp the stem.
-
Flowers: Its flowers are tiny (~2–4 mm) and blue to lilac in colour. The flowers are so small that they are often hidden among the upper leaves. These small, blue flowers only open on bright days.
- How it spreads. This weed only spreads by seed.
-
Habitat: It favours dry, sandy soils, and is often found along walls and paths. It is found in Canberra & The Southern Tablelands.
