Isopogon formosus, or Rose Cone Flower, in the Proteaceae family is a shrub that is endemic to areas near Albany and Esperance in Western Australia. It occurs naturally in heathland and woodland areas. It has an erect or bushy form and is usually between 1.5 and 2 metres high. The pink flowers appear from mid winter to early summer. Rounded "drumsticks" containing the seeds appear later, formed from the old flower parts.
The plant's leaves are divided, narrow, terete and about 5 cm long. It was first described by Robert Brown in 1810. 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. Because Isopogon was based on Isopogon anemonifolius, and that species had already been placed by Richard Salisbury in the segregate genus Atylus in 1807, Kuntze revived the latter genus on the grounds of priority, and made the new combination Atylus formosus for this species. However, Kuntze's revisionary program was not accepted by the majority of botanists. Ultimately, the genus Isopogon was nomenclaturally conserved over Atylus by the International Botanical Congress of 1905.
Isopogon formosus requires excellent drainage and full sun. It will not tolerate long periods of dryness or heavy frost. It is usually propagated from seed which germinates readily without pre-treatment. Cuttings are also successful using firm, current season's growth. Some limited work has been carried out by enthusiasts on the grafting of western species of Isopogon, onto eastern rootstock to extend the range where the plants can be grown. This offers the best chance for successful cultivation in humid areas.
