Plant in a well-drained soil in full or part sun and irrigate only occasionally as this plant is tolerant of extended dry periods once established. Hardy to 20 F. Makes a good container plant and can be kept compact with heavy pruning. The flowers appear in abundance and make a good show on the gray foliage - this is a very showy and attractive Grevillea.

Grevillea lavandulacea is naturally found across a wide range in Australia from the Grampians of Western Victoria to the Flinders Range in South Australia. 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. The specific epithet means "lavender" in reference to the wooly gray foliage looking like that of a lavender.

This plant is of garden origin and some speculate that rather than a selection of the species, it may actually be a hybrid similar to 'Poorinda Illumia' (thought to be a cross between G. lavandulacea and G lanigera), which may account for its durability and floriferous nature. The name comes from the town of Penola, which is in the southeast corner of South Australia. It has long been a plant in our nursery and has proven to be hardier to cold temperatures than other Grevillea lavandulacea we have grown. We started growing this excellent plant in 1999 and did not wish to discontinue growing it, but we unfortunately let our propagation stock slip away and last sold it in 2021. 

The information displayed on this page about Grevillea lavandulacea 'Penola' is based on the research we have conducted about it in our nursery library as well as from information provided by reliable online resources. We also include our own observations made about this plant as it grows in the nursery gardens and other gardens visited, as well how the crops of this plant have performed in the containers in our nursery field. We will also incorporate comments that we have received from others and welcome hearing from anyone with information about this plant, particularly if it includes cultural information that will aid others to better grow it.
