Diplolaena angustifolia 'Orange Urchin' (Yanchep Rose) - This small bushy shrub from Western Australia grows to 3 to 5 feet tall. It has narrow olive-green leaves with dense rusty hairs on the underside. In late winter through early spring appear the pendant 1 1/2" wide flowers that have a double row of short greenish cream-colored petal-like bracts and large brushes of pale orange stamens. The whole effect is a bit like looking at a upside down sea urchin. Plant in well-drained soils in full sun (coastal) to light shade with little irrigation - can tolerate regular watering if drainage is very good. Tolerates alkaline soils and coastal garden settings if given some protection from direct sea spray. Does best in near frost-free locations as temperatures below 26° F are liable to freeze back plant before flowering. An unusual and showy plant that is good mixed with other drought tolerant plants or used as a container plant. Diplolaena angustifolia was introduced through the UCSC Koala Blooms Australian Plant Introduction Program in fall 2005. Diplolaena from Greek 'diploos' meaning "double" and 'chlaina' meaning a "cloak" in reference to the double row of bracts that envelope the flower.
