This grevillea hybrid grows at least 6 feet tall and is generally broader than tall. The trunks are profusely branched, the twigs closely lined by narrow, pointed 3 inch leaves, colored a deep, rich green above and paler beneath. Though seldom completely out of bloom, it gives its most lavish display in early spring, with large deep ruby red, pendant flower clusters. Easily grown and hardy to 18 degrees F or less. Sun, well drained soil (usually the poorer, the better), and occasional to no supplemental watering when established. Many grevilleas are sensitive to phosphorus; never use high-phosphate fertilizers and, in general, feed them sparingly if at all.
