Silver Princess

Eucalyptus caesia 'Silver Princess'

The Story

Plant Bio

Eucalyptus caesia, commonly known as gungurru, is a small Western Australian mallee tree distinguished by its open, weeping habit and decorative, peeling reddish-brown 'minni-ritchi' bark. It naturally inhabits dry shrubby woodlands and granite outcrop crevices, developing a lignotuber that assists in surviving drought and wildfire.

'Silver Princess' is a horticulturally selected form celebrated for its larger, deep pink-to-red blossoms accented by bright yellow stamens and a heavy, powdery white waxy bloom coating the buds, fruit, and weeping branches. The mature canopy forms an elegant, light-filtering screen of pendulous, grey-green adult foliage.

Uses & Benefits:

Ornamental UsesFeatures striking weeping branches, powdery white stems, peeling minni-ritchi bark, and large pink-red blossoms.
Practical UsesFunctions as an elegant, light-filtering screen or architectural specimen for dry, sun-drenched landscapes.
Ecological BenefitsProvides a rich source of nectar for native birds, bees, and other beneficial insect pollinators.

Planting

How to Grow

  1. Select a planting site in full sun with excellent air circulation and highly permeable, free-draining soil.
  2. Dig a hole twice as wide as the root ball but no deeper, ensuring the top of the root crown sits slightly proud of the surrounding soil surface.
  3. Backfill with the native soil without adding organic matter or heavy fertilisers, and water in thoroughly to settle the roots.
  4. Apply a thin layer of coarse gravel mulch around the base, keeping it clear of the trunk to prevent collar rot.

Pro Tip

Elevate the root crown slightly above the surrounding soil level when planting and ensure sharp, gravelly drainage; excess moisture at the base or humid, stagnant air rapidly invites fungal decline and root rot.

Keep It Thriving

Care Guide

Do

  • Plant in a highly exposed, sun-drenched position to maximise flowering and prevent fungal issues.
  • Ensure the soil drains rapidly and completely after rainfall.
  • Prune lightly immediately after flowering to shape or remove damaged wood.

Don't

  • Do not plant in heavy, water-retaining clay soils or low-lying areas prone to waterlogging.
  • Do not over-fertilise, especially with high-phosphorus formulations.
  • Do not prune heavily into old, bare wood unless regenerating a severely damaged specimen.

When does Silver Princess bloom?

Silver Princess typically blooms in winter through spring. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.

Does Silver Princess need full sun?

Silver Princess does best in full sun (6+ hours).

Is Silver Princess drought tolerant?

Yes — once established (usually after the first full season), Silver Princess handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
