Round leaf Grevillea is a great cold hardy species from the highest elevations in the mountains of SE Australia. Handsome wavy round evergreen leaves frame showy pendant flower clusters from January to June. The sunset colored flowers feature orange/yellow/pink in various incarnations depending on the temperatures. Loved by over wintering Anna’s hummingbirds. Any reasonably well drained soil that has NOT been amended. Native soils are perfect, and tolerant of clay as well as sand. Great on slopes. Fast, large growing to 8′ x 8′ in 6 years. Little summer water required. Sporadic flowers appear year round. Avoid fertilizers. One of the best climate adapted Grevilleas that we have grown. Grows very fast with little water. Full sun and a hot position. Listed as endangered/threatened in Australia where it occupies just a half dozen sites in the high mountains. Extra reason to grow this fabulous multidimensional shrub that is good looking year round and blooms for a long, long period. No summer H20 when established. None.
