LATIN NAME: Eucalyptus camaldulensis
COMMON NAME: River Red Gum
Plant Profile
Known to gardeners as River Red Gum, Eucalyptus camaldulensis is a tree in the myrtle family (Myrtaceae), native to Australia. Across dry riverbeds of inland Australia, river red gum rises as great tree of waterlines, its broad, open crown held high above banks and its long, sickle-shaped leaves hanging in silver-blue drifts that catch afternoon light. Herb steadily grows into a rounded crown, with a mature height of 5-10 metres. It asks only for sun and deep, well-drained ground beside the water. Plants that offer this much while asking this little are rare enough to treasure.
Science & Biotechnology
Botanists studying the myrtle family regularly include Eucalyptus camaldulensis in comparative work, and the species also appears in horticultural trials aimed at gardeners and growers. For plant scientists, river red gum is a constant in studies of floodplain eucalypts and drought-hardy trees of warm regions, its deep roots and its water-finding habit drawing steady attention in work on dryland forestry and riverbank restoration. From a research perspective, species of this kind are valuable material for work on propagation and on the selection of uniform lines.
Uses & Benefits
Gardeners value River Red Gum for its ornamental character, and the plant also fits naturally into herb, vegetable and cutting gardens. Along slow rivers, river red gum shades water with wide canopy, holds banks against flood, and feeds bees with white summer blossom. Its hard, dense timber has served bridges and fence posts for a century and more, and tree now stands as emblem of the Australian river country. It earns its place wherever ground is deep and sun is strong. Establishment is uncomplicated, and afterwards ordinary care suffices.
Eucalyptus oil, rich in cineole, is a pharmacy standard in chest rubs, inhalants and lozenges for respiratory comfort, and the genus supplies honey, timber and the world’s most planted hardwoods. The oil is for external and properly diluted use only.
Growing from Seed
Seed is the natural starting point for River Red Gum, and the process is uncomplicated. Level a tray of loose seed compost, sow evenly, cover to about the seed’s own depth, and keep it moist in full light. A spell of cool, moist conditions ahead of sowing brings the seed along nicely and supports even germination. Move strong seedlings into individual pots, keep them in good light, and set them out when the weather and their size agree.
Our Take
River Red Gum settles in quickly once it finds its footing. Keep the sowing evenly moist at the start — that is the one real requirement.
