The species shows considerable variation in its habit and other characteristics. It may be prostrate or erect, the latter forms growing from 0.3 to 1.5 metres in height. The red flowers may occur throughout the year, but are most prolific in winter and spring. It has hairy leaves and branchlets, giving rise to the specific epithet lanigera derived from the Latin words lana (wool) and ger (to bear or carry).
It's important to water moderately, always waiting for the substrate to be dry; reduce watering in winter. They do not need fertilizers. Prune lightly in fall to maintain a compact appearance. They are plants resistant to the usual pests but sensitive to excess humidity.
They can be tip-pruned when young - when mature, just cut off any straggly branches. The larger grevilleas, like Grevillea 'Honey Gem' can grow into small trees and eventually benefit from renovation pruning.
It can grow in a wide variety of climates, being able to withstand temperatures as low as −5 °C (23 °F), while tolerant of humid subtropical climates such as in Brisbane. Once established, it will tolerate extended dry periods.
