The Story
Plant Bio
Hymenosporum flavum, the native frangipani, is an evergreen Australian tree with a slender, upright crown and branches held in distinct horizontal tiers. The large, highly fragrant flowers open cream before ageing to deep sulphur-yellow, appearing in terminal clusters from spring to early summer.
This species is distinguished by its remarkably narrow, columnar growth habit and glossy, dark green leaves that cluster at the branchlet tips. Unlike the exotic Plumeria, it maintains its lush foliage year-round and adapts well to cooler temperate climates.

Planting
How to Grow
- Select a position in full sun to partial shade with fertile, well-drained loam or alluvial soil.
- Dig a hole twice the width of the root ball and plant at the same depth as the container level.
- Water deeply and regularly during the first few seasons to establish a deep, resilient root system.
- Apply a balanced, general-purpose slow-release fertiliser in early spring to support new growth.
Pro Tip
Prune young trees early to establish a strong central leader and prevent leggy growth; avoid cutting back hard into old, leafless wood as it rarely shoots.

Care Guide
Do
- Water regularly during hot, dry summer spells, especially while the plant is young.
- Prune lightly immediately after flowering to maintain a dense, bushy canopy.
- Protect young plants from heavy, burning frosts until they are fully established.
Don't
- Do not plant in heavy, poorly draining clay or areas prone to prolonged waterlogging.
- Do not prune heavily into old, bare wood where new shoots may fail to emerge.
- Do not mistake natural seasonal leaf-shedding for a disease or overwater in response.

Common Questions
Native Frangipani questions
What zones can Native Frangipani grow in?
Native Frangipani is hardy in USDA Zones 9–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
When does Native Frangipani bloom?
Native Frangipani typically blooms in spring through summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Native Frangipani need full sun?
Native Frangipani does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Native Frangipani drought tolerant?
Yes — once established (usually after the first full season), Native Frangipani handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
