Royal Grevillea

Grevillea victoriae

The Story

Plant Bio

Grevillea victoriae is an erect to wide-spreading evergreen shrub native to the mountainous regions of southeastern Australia, reaching five to thirteen feet in cultivation. The alternate, lance-shaped leaves feature dark green upper surfaces and dense, silvery-grey woolly undersides, complemented by soft bronze-tinted new growth.

This species is distinguished as one of the cold-hardiest members of its genus, reliably tolerating temperatures down to 5°F once established. Pendant, conical clusters of red to orange flowers with prominent curved styles open from fall through spring, providing a critical winter food source for hummingbirds.

Uses & Benefits:

Ornamental UsesProvides year-round structure with striking bicolored foliage and pendant red-orange flower clusters that bloom through the coldest months.
Practical UsesOffers exceptional drought tolerance and wind resistance once established, making it ideal for difficult sloped or coastal sites.
Ecological BenefitsServes as a vital winter nectar source for hummingbirds and other cold-season pollinators when few other plants are in bloom.

Planting

How to Grow

  1. Select a planting site in full sun to light shade with coarse, sandy, or loamy soil that drains rapidly.
  2. Dig a hole twice as wide as the root ball but no deeper, ensuring the crown sits slightly above the surrounding soil level to prevent rot.
  3. Backfill with native soil without adding organic amendments or phosphorus-rich fertilizers.
  4. Water deeply to settle the soil, then establish a strict watering schedule only until the root system is established.

Pro Tip

Plant on a slope or in a raised bed to guarantee the sharp drainage this species demands, and never apply general-purpose fertilizers containing phosphorus.

Care Guide

Do

  • Plant on a slope or raised bed to ensure rapid drainage.
  • Use only specialty low-phosphorus or native-formulated fertilizers.
  • Tip-prune young plants regularly to encourage a dense, bushy habit.

Don't

  • Do not plant in heavy clay or waterlogged soils.
  • Never cut back into old, leafless woody stems lacking dormant buds.
  • Do not overwater once the plant is established.

Does Royal Grevillea need full sun?

Royal Grevillea does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.

Is Royal Grevillea drought tolerant?
