Per San Marcos Growers website:
Grevillea 'Cherry Royal' - A moderately-fast dense-growing shrub to 2 feet tall by 3 feet wide wit...Read Moreh soft olive-green oval leaves and cherry red "spider" type flowers in spring and a scattered bloom at other times of the year. Plant in full sun to light shade in a well-drained soil with occasional to little irrigation. It should tolerate inland heat and has been frost hardy to at least 20° F. This plant was discovered as a seedling volunteer in 2001 growing on the grounds of the University of California Santa Cruz arboretum where is was given the temporary name of Grevillea sp. - garden seedling 2001.289. The genus name Grevillea honors Charles Francis Greville (1749-1809), a patron of botany, a very close friend of Sir Joseph Banks, and president of the Royal Society of London. We like this plant but it has been hard to maintain in containers over summer in our climate."
