Derivation of Name: Scaevola...From Latin, scaevus, on the left side, referring to the flowers which have petals arranged to one side - fan shaped.
aemula...From Latin aemulus, comparing with or rivalling - of uncertain origin.
Scaevola is a genus of about 70 species, most of which occur in Western Australia. They are mostly small, herbaceous plants distinguished by their fan-shaped flowers.
|Scaevola aemula is probably the most commonly
grown species. Because of its wide range, a number of forms exist but, in
cultivation, it is typically a sub-shrub to about 150mm high by a width of
half a metre. The leaves are 10 to 50 mm long, oval or wedge shaped and sometimes
toothed. Flowers are seen in spring and summer, are mauve to purple and
25-30 mm in diameter.
This is a reasonably hardy to very hardy species in well drained, moist soils in temperate climates. However, some care in selection of forms is advisable because those native to semi arid areas may not grow well in areas of high rainfall, and vice-versa. A position in full sun or light shade is usually suitable and the species makes an excellent subject for a hanging basket.
Propagation is difficult from seed but cuttings strike very easily from firm, current season's growth.
Conservation Status: Endangered in the wild in Tasmania (DPIW listed)
An erect perennial herb that grows up to 60cm tall, blue-green in colour and covered with short hairs.
Leaves: composed of 5 leaflets, long, narrow and wedge-shaped. Upper 3 leaflets 1-4cm long, the lower 2 are small and reduced.
Flowers: pea-like, between 14-20mm long, white to pink colour, in clusters of 3-8 on long stalks in the leaf axils. Flowering from spring to early summer.
Fruit: a straight pod between 3-5cm long (description from Cunningham et al 1992, Woolcock 1991).
Occurs in all Australian states, but in Tasmania is found in Poa tussock grassland, low coastal shrubbery and on dunes around the State.
Status: considered rare in Tasmania but known reserves are as follows:
Well reserved in the Arthur-Pieman Conservation Area, Denison Rivulet Conservation, Foster Islands Nature Reserve, Mt Field National Park, Narawntapu National Park, Pieman River State Reserve, Rocky Cape National Park, Southwest Conservation, St Helens Point Conservation Area, Tooms Lake Forest Reserve and the Waterhouse Conservation Area.

ERYNGIUM VESICULOSUM Apiaceae
Prostrate perennial plant with branches to 30 cm. The leaves have deeply divided lobes each of which ends in a sharp spine. The base of the stem has a rosette of leaves and the branches have a pair of small leaves at each node. A flower head grows from the central rosette and others from nodes on the branches. Flowers are white to pale blue in an oval to globular head which is surrounded by bracts and sepals with sharp or spinous tips.
Flowering period: October to February
Distribution: Sandy and marshy flats near the coast.
Cultivation: Suitable for containers and is attractive when in flower. Propagate from seed or by division.
