Grevillea 'Poorinda Signet' - A medium to large shrub to 6 to 9 feet tall and wide with arching branches or 1 inch long by 1/4 inch wide leaves that are dark green on the upper surface with a dense covering of silvery hairs below with recurved margins and a sharp pointed tip. The dense silvery hairs also cover new shoots and the inflorescence with its pale pink flowers and darker styles, which appear late winter through spring, and are held in terminal clusters on short stems tight with the foliage. Plant in full sun to part shade in well-drained acidic to neutral soils. Hardy to moderate frost and extended dry periods. Responds well to light pruning or shearing. A number of Grevillea hybrids bear the name “Poorinda”, the name of a property owned by the late Leo Hodge (1904 – 1994) and was located at W Tree, near the Snowy River, north of Buchan in Victoria, Australia. Mr. Hodge was a grower of grevilleas who worked on hybridizing between the species from 1952 until 1968 with more than 50 Poorinda cultivars registered. Only a few of them have stood the test of time and are still available including this very nice cultivar that was thought to be a hybrid between Grevillea juniperina and G. lanigera and was received by the Australian Cultivar Registration Authority on October 9, 1974. It is being introduced into cultivation in the US by the University of California, Santa Cruz Koala Blooms Australian Plant Introduction Program. We received this plant originally as UCSC 94.928.  The information on this webpage is based on research conducted about this plant in our nursery library, from online sources, as well as from observations made of it as it grows in the nursery in containers, in the nursery's garden and in other gardens where we have observed it growing. We will also incorporate comments received from others and welcome getting feedback from those who may have additional information, particularly if this information includes cultural information that would aid others in growing  Grevillea 'Poorinda Signet'.
