I have not grown this plant; however, I have observed it growing in Maui, Hawaii. Rosemary grevillea (Grevillea rosmarinifolia). Its growth habit, leaf size and spacing of leaves varies depending upon where it is grown. It is one of the few grevillea that does well in slighty alkaline soils. It will receive frost damage in the USA in zones below 9 (9 and above are the most suitable zones). Rosemary grevillea can become straggly; however, heavy pruning may kill it. Light pruning leaving enough foliage for regrowth done after blooming is recommended. Fertilizing is not necessary. High phosphorus fertilizers may kill the plant.

Grevillea rosmarinifolia is one of most widely cultivated species of grevillea. There are 2 subspecies of Grevillea rosmarinifolia which sometimes leads leads to confusion when attempting to identify the plant. One form is a spreading tall shrub with prickly foliage and red flowers. Its prickly foliage provides nesting sites for native birds and its nectar-rich blooms attract bird as well. Another form which is suitable for small gardens, Grevillea rosmarinifolia var lutea, has cream flowers and develops into a medium shrub with upright growth habit. It is easily propagated from cuttings.

Cream & hot pink fall and winter blooms. Fast growing and loves our valley heat. Give excellent drainage and low water. A plus for some winter time color. Hummingbirds like the flowers.
