Upright, clump-forming or spreading herbs. At least 6 species occur near Wagga Wagga, both annual and perennial. Leaves vary widely between species but are usually confined to the lower half of each stem. The uppermost leaves tend to be the small-est. Flowers are sky blue and star shaped, varying in size between species, and usually have five sepals (petal-like ‘points’). Variants with 4, 6 and 10 sepals are known. Seed is tiny (
Seed germinates without pre-treatment but results are often poor. Large numbers of seeds are usually needed. Germination may be enhanced by cold treatment (3-5∞C for 3 months) or using year-old seed. Seed may require light. Also from cuttings.
Year-round, though spring and summer are favoured.
Ubiquitous by roadsides and in reserves. Can form extensive colonies on the margins of roads. Annual bluebell (W. gracilenta) occurs as a weed of pastures and crops.
