The Story
Plant Bio
Cassinia arcuata, commonly known as drooping cassinia, is a multi-stemmed, evergreen shrub native to southeastern Australia that reaches heights of forty to eighty inches in cultivation. It features a dense, twiggy framework clothed in fine, linear leaves that release a pungent, resinous, petrol-like aroma when crushed.
This species is distinguished by its drooping, pyramidal panicles of tiny, yellowish-green to greenish-bronze flower heads that dry to a pale ochre or white. Unlike similar species, its foliage has strongly revolute margins with a mid-green upper surface and a densely white-cottony underside.

Planting
How to Grow
- Select a planting site in full sun to partial shade with exceptionally well-drained soil.
- Dig a hole twice the width of the root ball and set the plant at its original container depth.
- Backfill with native soil without adding organic matter or fertilizers, which can cause weak growth.
- Water sparingly during the establishment phase, then withhold supplemental water once the root system is active.
Pro Tip
Nip-prune only the fresh green shoots immediately after flowering; cutting back into old, leafless brown wood fails to stimulate new growth and leaves permanent bare patches.
Keep It Thriving
Care Guide
Do
- Prune lightly after each flowering cycle to maintain a dense, compact shape.
- Ensure the soil drains rapidly to prevent root rot.
- Grow in poor, low-nutrient soils where the plant naturally thrives.
Don't
- Do not cut back into old, leafless brown wood, as it will not reshoot.
- Do not apply high-phosphorus or standard garden fertilizers.
- Do not plant in low-lying areas prone to standing water or waterlogging.

Common Questions
Drooping Cassinia questions
What zones can Drooping Cassinia grow in?
Drooping Cassinia is hardy in USDA Zones 8–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
When does Drooping Cassinia bloom?
Drooping Cassinia typically blooms in spring through autumn. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Drooping Cassinia need full sun?
Drooping Cassinia does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
Is Drooping Cassinia drought tolerant?
Yes — once established (usually after the first full season), Drooping Cassinia handles dry spells with minimal watering. Water deeply its first year to build the root system that makes that possible.
