Eremophila bowmanii explained

Eremophila bowmanii, also known as silver turkeybush, Bowman's poverty bush and flannel bush, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to New South Wales and Queensland in Australia. It is a low to medium, spreading shrub with silvery-grey, hairy foliage and blue to lilac flowers, and sometimes grows in dense thickets with mulga.

Description

Eremophila bowmanii is a shrub which usually grows to a height and width of 1.5sigfig=1NaNsigfig=1 grows but sometimes as high as 3sigfig=1NaNsigfig=1. Its branches, leaves, flower stalks and sepals are all covered with tangled, silvery hairs making the plant appear silvery-grey. The leaves are NaNsigfig=1NaNsigfig=1 long, NaNsigfig=1NaNsigfig=1 wide and range in shape from linear to egg-shaped or almost circular.[1] [2] [3] [4] [5]

The flowers are usually borne singly in leaf axils on a stalk NaNsigfig=1NaNsigfig=1 long. There are 5 pointed, green to purple sepals which are NaNsigfig=1NaNsigfig=1 long and are covered with silvery hairs. The petals are about NaNsigfig=1NaNsigfig=1 long and joined at their lower end to form a tube. The tube is a shade of purple or lilac, rarely white, sometimes with small purple spots inside the tube. The tube and the petal lobes on its end are mostly glabrous except for inside the tube which is woolly. There are 4 stamens which are enclosed in the petal tube. Flowering mostly occurs from winter to late spring and is followed by fruit which are oval-shaped, NaNsigfig=1NaNsigfig=1 long and woody with a papery covering.

Taxonomy and naming

The species was first formally described by Ferdinand von Mueller in 1861 and the description was published in Fragmenta Phytographiae Australiae.[6] [7] The specific epithet (bowmanii) honours the collector of the type specimen, Edward M. Bowman, a station worker.[8]

In 1992, Robert Chinnock described three subspecies in his book, Eremophila and Allied Genera: A Monograph of the Plant Family Myoporaceae, and the names are accepted by the Australian Plant Census:

Distribution and habitat

Eremophila bowmanii is widespread and common in central parts of northern New South Wales and southern Queensland growing in red soils in mulga, mallee and woodland. (There is one record from South Australia.)

Ecology

This species sometimes grows in dense stands, sometimes indicating overgrazing of grasses by livestock but it is not usually itself eaten by cattle or sheep.

Conservation status

Eremophila bowmanii is listed as "not at risk".

Use in horticulture

Silver turkeybush is a popular garden plant and one of the most attractive small, grey-leaved eremophilas. It can be propagated from seed or from cuttings but needs to be grafted onto Myoporum species in temperate areas like Sydney or when grown in alkaline soil. It grows best in well-drained soil in a sunny position and is drought and frost tolerant.
