Eremophila christophori

Eremophila christophori is an upright shrub usually growing to 2.5 m (8 ft) high and 2 m (7 ft) wide. The leaves are arranged alternately along the stems and more or less overlap each other. They are elliptic to lance-shaped, mostly 10.5–25 mm (0.4–1 in) long and about 2.5–7 mm (0.1–0.3 in) wide, mostly glabrous and bright green, sometimes faintly purple.[3][4]

The flowers are borne singly in leaf axils and lack a stalk. There are 5 linear, green sepals with the top sepal greatly reduced in size while the other 4 sepals are 4–8 mm (0.2–0.3 in) long and overlap each other. The petals are 18–30 mm (0.7–1 in) long and joined at their lower end to form a tube. The petal tube is white, blue, or a shade of pink to lilac-coloured, covered on the outside with short hairs while the inside is filled with spidery hairs. Flowering occurs for most of the year[2] but mainly in spring to mid-summer[4] and is followed by fruits which are dry, oval to cone-shaped, wrinkled and 5–8.5 millimetres (0.2–0.3 in) long.[3]

Eremophila christopheri growth habit

Eremophila christophori was first formally described by Ferdinand von Mueller in 1875 and the description was published in Fragmenta phytographiae Australiae.[5][6] The specific epithet (christophori) honours Christopher Giles, the collector of the type specimen.[7]

This eremophila occurs in a band extending east north east from the MacDonnell Ranges west of Alice Springs to the border with Queensland where it grows in sandy soils often over laterite or limestone on low hills.[3]

Eremophila christophori is listed as "of least concern" by the Northern Territory Parks and Wildlife Conservation Act.[8]

This eremophila is rarely without flowers in the garden. It is hardy and some specimens have been in cultivation for more than 30 years. It can be propagated from cuttings or grafted onto Myoporum. Although it prefers well drained soil it will grow in heavier soils to produce a more open plant. It is drought hardy, tolerates light frost and is fast growing in well-drained soil in a sunny position.[2][4][9]
