Hummingbird bush. Variable in both size and foliage color, the hummingbird bush ranges from a prostrate 3’ form to an 8’ tall upright shrub. The branches possess a graceful, rounded form and bear dark green or sometimes pubescent gray leaves. Bright red clusters of flowers, in late winter and spring, are tipped yellow or green and often appear sporadically throughout the year. Plants feature an open form that is less suitable for hedging than that of the rosemary grevillea. Surprisingly shade and cold tolerant, the forms we carry have survived 17F with modest damage.
