Eucalyptus steedmanii: A Rare Eucalyptus Worth Knowing About

If you’ve stumbled across the name Eucalyptus steedmanii in your plant research, you’ve discovered one of the more elusive members of the eucalyptus family. This Australian native isn’t your typical backyard eucalyptus, and there’s a good reason you haven’t seen it at your local nursery.

What Makes This Eucalyptus Special?

Eucalyptus steedmanii appears to be a lesser-known species that’s endemic to Western Australia, following the typical pattern of many specialized eucalyptus species that evolved in specific microhabitats. Like its more famous cousins, it’s part of the massive eucalyptus genus that has given us everything from towering forest giants to compact mallee shrubs.

Where Does It Come From?

Based on available information, this species is native to Western Australia, though specific distribution details are limited in horticultural literature. Many eucalyptus species from this region are highly specialized and adapted to very specific soil types, rainfall patterns, and growing conditions.

Should You Plant Eucalyptus steedmanii?

Here’s where things get a bit tricky. The limited availability of information about this species suggests it may be:

  • Rare or endangered in its native habitat
  • Extremely difficult to propagate or grow outside its natural range
  • Not yet thoroughly studied for horticultural potential
  • Simply not in commercial cultivation

If you’re interested in Australian native plants, particularly eucalyptus species, there are many well-documented alternatives that offer similar benefits without the uncertainty.

Better Alternatives to Consider

Instead of pursuing this elusive species, consider these well-established eucalyptus options:

  • Eucalyptus leucoxylon (White Ironbark) – Great for wildlife and relatively compact
  • Eucalyptus torquata (Coral Gum) – Beautiful flowers and manageable size
  • Eucalyptus caesia (Gungurru) – Stunning weeping habit with silver bark
  • Eucalyptus macrocarpa (Mottlecah) – Large, showy flowers on a compact shrub

If You’re Determined to Find It

Should you encounter Eucalyptus steedmanii through specialized native plant societies or botanical collections, approach with caution. Only source plants from reputable suppliers who can guarantee the material is ethically and sustainably obtained. Never collect from wild populations, especially if this species proves to be rare or threatened.

Growing Tips for Rare Eucalyptus

If you do manage to acquire this species, treat it like other Western Australian eucalyptus:

  • Provide excellent drainage – these plants hate wet feet
  • Choose a sunny location with good air circulation
  • Use low-phosphorus fertilizers (eucalyptus are adapted to nutrient-poor soils)
  • Water deeply but infrequently once established
  • Protect from strong winds while young

The Bottom Line

While Eucalyptus steedmanii is certainly intriguing from a botanical perspective, the lack of readily available information suggests it’s not the best choice for most gardeners. If you’re passionate about Australian natives, focus on the many spectacular and well-documented species that are readily available and proven in cultivation.

Sometimes the most responsible thing we can do as gardeners is to appreciate rare plants from a distance while choosing alternatives that won’t put pressure on potentially vulnerable wild populations. Your garden can still showcase the incredible diversity of Australian flora without needing the rarest specimens.
