Alpine Grevillea is a cold hardy, handsome, adaptable evergreen shrub that is good looking at all times. In late winter/early spring flossy white flowers explode over the bush and emit an intense honey fragrance. Each small leaf is olive/ochre green on the surface and silver below. Dense, fine textured very rounded compact shrub to 4′ tall and 5′ wide in 5 years. Maxes out at that height but continues to gain width. Avoid enriched, over-improved soil. Best in unimproved native or even poor soils with sharp drainage. Little water ever once established. Cold hardiest Grevillea taking temperatures to just near 0ºF with no problem. Tolerates subfreezing wind as well as ice and snow. Easy to grow if left strictly alone. It may be pruned in spring to limit the size- prune tips. Very good landscaping plant. The powerful honey fragrance of the flowers is detectable for quite a distance on warm days. But for this it would make a good cut flower- fragrance is a little too strong. Cut branches last for several weeks in a vase and foliage is handsome. Takes very well to pruning. Good deer resistance. Video below is of a plant in full bloom. Takes a moment for the video to load. Not tolerant of shade at all. Hates it. Revels in full hot sun. Limited quantities.
