Isopogon anemonifolius, commonly known as broad-leaved drumsticks,[2] is a shrub of the family Proteaceae that is native only to eastern New South Wales in Australia.

Its leaves are divided and narrow, though broader than those of the related Isopogon anethifolius, and have a purplish tinge during the cooler months.

[3] A long-lived plant reaching an age of up to 60 years, I. anemonifolius resprouts from its woody base, known as a lignotuber, after bushfire.

I. anemonifolius grows readily in the garden if located in a sunny or part-shaded spot with sandy soil and good drainage.

The perianth, a tube that envelopes the flower's sexual organs, splits into four segments, revealing a thin delicate style tipped with the stigma.

[6] Swedish naturalist Daniel Solander, after collecting a specimen at Botany Bay in 1770 on the first voyage of Captain James Cook, was the first to write of this species.

[5] In 1796, English botanist Richard Salisbury published a formal description of the species,[13] from a specimen collected in Port Jackson (Sydney).

[16] In 1799, the Spanish botanist Antonio José Cavanilles described Protea tridactylides,[17] later identified as a junior synonym by Salisbury and the English horticulturalist Joseph Knight.

[23] In 1891, German botanist Otto Kuntze published Revisio generum plantarum, his response to what he perceived as a lack of method in existing nomenclatural practice.

[24] Ultimately, the genus Isopogon was nomenclaturally conserved over Atylus by the International Botanical Congress of 1905.

[28] English botanist George Bentham tentatively described variety pubiflorus in his 1870 work Flora Australiensis.

Australian botanist Edwin Cheel described forma simplicifolia in 1923, from collections from Mount Victoria and Hornsby.

[31] I. anemonifolius is found along the east coast of New South Wales, from near the Victorian border almost to (and possibly reaching) Queensland.

[2] It occurs naturally from sea level to 1200 m (4000 ft) and is found on low-nutrient sandstone soils in heathland and dry sclerophyll woodland, particularly along ridges or tops of hills.

[11] Typical woodland trees it is associated with include the scribbly gums Eucalyptus haemastoma and E. sclerophylla, yertchuk (E. consideniana), yellow bloodwood (Corymbia eximia), red bloodwood (C. gummifera) and smooth-barked apple (Angophora costata), and heathland plants such as rusty banksia (Banksia oblongifolia), swamp banksia (B. paludosa), mountain devil (Lambertia formosa), conesticks (Petrophile pulchella), tick bush (Kunzea ambigua), forest oak (Allocasuarina torulosa) and Hakea laevipes.

The resultant new growth takes two years to flower,[11] though older plants with larger lignotubers are able to re-grow more quickly.

[32] The seeds of I. anemonifolius fall directly to the ground or are blown a short distance by wind.

[36] Isopogon 'Woorikee 2000' is a selected dwarf form of I. anemonifolius, propagated by Bill Molyneux of Austraflora Nursery in Victoria.
