It is helpful to mound the soil to improve drainage. Pests are not a major problem with Eremophila subfloccosa but it can suffer from attack by the fungal diseases of Botrytis spp. [2][3], The flowers are borne singly or in pairs in leaf axils on woolly stalks 2–5.5 mm (0.08–0.2 in) long. Eremophila nivea. Eremophila nivea is an erect shrub which grows to a height of between 0.8–1.6 m (3–5 ft). Propagation from seed of Eremophila species is unreliable. The mauve or lilac coloured flowers are about 20 mm long and tubular in shape. Classified as 2E under the ROTAP * system. Cultivation of the E.nivea in a container probably provides the best chance of success in humid climates as this makes it easier to provide the necessary growing conditions. Eremophila nivea is a small shrub to about 1 -1.5 metres high by a similar width. There are 5 overlapping, triangular to lance-shaped, tapering sepals which are 14–21 mm (0.6–0.8 in) long and have purplish-black tips. Its branches, leaves and sepals are covered with a layer of soft white to greyish matted hairs giving the plant a silvery-greyish appearance. It will grow in most soils, is both drought and frost tolerant but needs to be grown in full sun. Needs good drainage and a sunny spot. It has been in cultivation for many years but, like most eremophilas, it is best suited to dry climates in well drained soils. The soft leaves are linear to lance-shaped to about 30 mm long by 4 mm wide. The outer surface of the tube and both surfaces of the lobes are glabrous but the inside of the tube is filled with long, soft hairs. The 4 stamens are fully enclosed in the petal tube. In nature it is a rare shrub with hairy branches and leaves, and blue, purple or violet flowers. Eremophila is a large genus of 214 species, all endemic to Australia. In those areas, the hairy foliage is subject to fungal diseases which are difficult to control. [2] It grows in sandy clay and clay-loam. [6] Only a few populations are known, some of which are in danger of roadworks as they occur on road verges. [7], Although rare in nature, silky eremophila is often available in specialist nurseries with its popularity in part due to its soft, silvery-grey foliage and pale to deep blue flowers. Listed as Endangered under the EPBC Act* (facing a high risk of extinction in the wild in the short term, as determined in accordance with prescribed criteria). The leaves are arranged alternately along the branches and are linear in shape, mostly 8–18 mm (0.3–0.7 in) long, 1.5–2.5 mm (0.06–0.1 in) wide and have a covering of woolly hairs. A good plant for drier areas, as it will be short lived in more humid areas. Other names.

To maximise the chances of success, the plant should be grown in an open, sunny position with good air circulation and the foliage should be kept as dry as possible. The soft leaves are linear to lance-shaped to about 30 mm long by 4 mm wide. The latter involves splitting the fruits in halves and quarters but some seeds are inevitably damaged during the process. [2], Eremophila nivea is only known in the wild from near Three Springs in the Avon Wheatbelt and Yalgoo biogeographic regions. The best method of avoiding fungal diseases is to grow plants in open areas allowing plenty of air movement and sunshine. Botanical name. [3], This species is classified as "Threatened Flora (Declared Rare Flora — Extant)" by the Department of Environment and Conservation (Western Australia)[6] and an Interim Recovery Plan has been prepared. Flowering occurs from August to October and the fruits which follow are dry, woody, oval-shaped with a pointed end and 4.5–6 mm (0.18–0.24 in) long. The petal tube is lilac-coloured, white with yellow-brown spots inside. Although most plants sold are grafted to improve the hardiness and vigour of the plant, this does not fully overcome foliage problems. The fruits are egg shaped and about 6 mm long. They are generally plants of inland and arid areas and are popular with Australian plant enthusiasts. Flowers are seen from late winter to early summer. Species. It has very hairy stems and foliage giving the plant a very distinctive silvery appearance. E.nivea is one of the most spectacular members of the genus. Eremophila nivea – emu bush Eremophila nivea – emu bush A beautiful silvery foliaged shrub with purple tubular flowers in spring and summer. Eremophila nivea, commonly known as silky eremophila, is a flowering plant in the figwort family, Scrophulariaceae and is endemic to Western Australia. The petals are 15–23 mm (0.6–0.9 in) long and are joined at their lower end to form a tube. It benefits from regular pruning after flowering to preserve its shape and to help prevent fungal diseases. The plant is reported to be frost sensitive. * EPBC Act = Environment Protection and Biodiversity Conservation Act 1999; ROTAP = Rare or Threatened Australian Plants (Briggs and Leigh, 1988) For further information refer the Australian Plants at Risk page. [2][3], The first formal description of this species was published in 1986 by botanist Robert Chinnock and the description was published in Nuytsia. It has very hairy stems and foliage giving the plant a very distinctive silvery appearance. However, during extremely dry periods, it responds well to deep soakings. Eremophila nivea is an erect shrub which grows to a height of between 0.8–1.6 m (3–5 ft). Its branches, leaves and sepals are covered with a layer of soft white to greyish matted hairs giving the plant a silvery-greyish appearance. Eremophila nivea is a small shrub to about 1 -1.5 metres high by a similar width. Eremophila Eremophila. E.nivea can be grown from cuttings but the foliage may easily rot under misting conditions. South Western Australia on sandy clay and clay loam. Genus. A number of treatment methods have been tried including sowing the ripe fruits, sowing of aged and washed fruits and splitting the fruits to extract the seeds prior to sowing. Silky eremophila, Emu bush, Silky emu bush. Grafting onto a Myoporum rootstock is the preferred method of propagation. and Alternaria spp. It can be propagated from cuttings or by grafting onto Myoporum rootstock and opinion amongst horticulturalists differ on which is the better method. A form with white flowers is also sometimes available. [4] The specific epithet (nivea) is a Latin word meaning "snowy" or "snow-white"[5] in reference to the colour of the hairs on the branches and leaves of this species. It can be difficult to grow in more humid, temperate areas although many people take up the challenge!
