Common name: Short-spiked Grevillea. This species is native to Western Australia. They are wide-growing evergreen shrubs that can reach 2 meters (6.56 feet) in height. The leaves are linear and dark green. The attractive flowers are pink. They bloom from winter to spring. They are used in shrubby groups, in hedges and screens, on slopes, in rockeries, in Eucalyptus understory, and in pots for terraces and patios. Grevillea brachystachya grows in full sun or semi-shade exposure. They resist well the heat of the Mediterranean summer and frosts down to -8 ºC (17.6 ºF). They do not resist salinity; they are not recommended for coastal gardens. They prefer a slightly calcareous and well-drained soil; they can be grown in poor, sandy or rocky soils. Water moderately throughout the year waiting for the substrate to dry. The adult specimens resist prolonged drought. They do not need fertilizers. Prune lightly after flowering to maintain a compact appearance. They are resistant plants to the usual pests and diseases. They propagate by seeds sown in spring or autumn in the seedbed and by cuttings in summer. |
