Corymbia 'Summer Beauty'

The Story

Plant Bio

Corymbia is a genus of evergreen Australian trees, formerly classified under Eucalyptus, characterised by terminal, corymb-like flower clusters and woody urn-shaped fruit. These trees thrive in well-drained soils and rely on nectar-rich blossoms to attract native birds and insects.

'Summer Beauty' is a garden-bred hybrid cultivar that forms a small grafted tree with a dense, irregular rounded canopy and slightly weeping foliage. It produces large terminal clusters of musk stick-pink flowers with soft apricot tones from early summer to autumn, followed by large decorative gumnuts.

Uses & Benefits:

Features large, dense terminal clusters of musk stick-pink flowers with soft apricot tones and striking bronze-red new foliage.

Functions as an excellent small specimen tree for urban gardens and coastal areas due to its compact size and high wind tolerance.

Provides a rich source of nectar for honeyeaters, lorikeets, native bees, and other beneficial insects.

Planting

How to Grow

Select a planting site in full sun with exceptionally well-drained soil such as sandy loam or clay loam.
Dig a hole twice as wide as the root ball but no deeper, ensuring the graft union remains well above the soil level.
Gently backfill the hole, firming the soil lightly, and water deeply to settle the roots.
Apply a thick layer of organic mulch around the base, keeping it clear of the trunk to prevent rot.
Water regularly during the first growing season until the root system is fully established.

Pro Tip

Remove any shoots emerging from below the graft union immediately to prevent the vigorous rootstock from overtaking the pink-flowering scion, and avoid high-phosphorus fertilisers which cause severe root burn.

Keep It Thriving

Care Guide

Do

Remove any suckers arising from below the graft union immediately.
Use only low-phosphorus fertilisers formulated specifically for Australian native plants.
Ensure the planting site has excellent drainage to prevent root rot.

Don't

Do not prune hard into old, leafless wood as it may fail to shoot.
Do not plant in heavy, waterlogged, or poorly drained clay soils.
Do not use general-purpose garden fertilisers containing high levels of phosphorus.
