Broad-leaved Drumsticks

Isopogon anemonifolius

The Story

Plant Bio

Isopogon anemonifolius, known as broad-leaved drumsticks, is an upright, multi-stemmed evergreen shrub native to the sandstone soils of eastern New South Wales. The stiff, deeply divided, leathery leaves take on a distinct purplish tinge during the cooler fall and winter months.

The species is distinguished by its soft yellow flowers clustered in dense, globose terminal heads that resemble drumsticks, which later mature into prominent, spherical gray cones. In exposed coastal sites, the plant naturally adapts by adopting a dwarfed, tufty groundcover habit to withstand strong sea winds.

Uses & Benefits:

Produces distinctive, bright yellow drumstick-like flower heads followed by decorative, long-lasting gray cones.

Highly tolerant of coastal salt spray and wind, making it an excellent structural choice for exposed seaside gardens.

Provides minimal ecological value in North America, but serves as a nectar source for generalist insects.

Planting

How to Grow

Select a planting site with exceptional, sharp drainage and full sun to partial shade.
Incorporate sand or light sandy loam to ensure the soil remains lean and acidic to neutral.
Water moderately during establishment, then reduce frequency to allow the soil to dry out between waterings.
Avoid any fertilizers containing phosphorus, as this will cause toxicity and rapidly kill the root system.

Pro Tip

Never prune stems back past the active green foliage into old, leafless wood; these branches lack dormant buds and will fail to regenerate, leaving permanent bare patches.

Care Guide

Do

Grow in highly porous, sandy, or sandstone-derived soils.
Ensure excellent air circulation around the foliage to prevent powdery mildew.
Use exclusively low-phosphorus, native-formulated fertilizers.

Don't

Never prune back into old, bare wood lacking green leaves.
Do not overwater or allow the roots to sit in heavy, poorly drained clay soils.
Avoid applying standard general-purpose garden fertilizers.
