Adenanthos obovatus, commonly known as basket flower (which usually refers to Centaurea, though), or, jugflower, is a shrub of the plant family Proteaceae endemic to Southwest Australia. Described by French naturalist Jacques Labillardière in 1805, it had first been collected by Archibald Menzies in 1791. Within the genus Adenanthos, it lies in the section Eurylaema and is most closely related to A. barbiger. A. obovatus has hybridized with A. detmoldii to produce the hybrid A. × pamela. Several common names allude to the prominent red flowers of the species. It grows as a many-stemmed spreading bush up to 1 m (3.3 ft) high, and about 1.5 m (4.9 ft) across, with fine bright green foliage. Made up of single red flowers, the inflorescences appear from April to December, and peak in spring (August to October).
The shrub grows on sandy soils in seasonally wet lowland areas as well as hills and dunes. It regenerates after bushfire by resprouting from its underground lignotuber. Pollinators include honeyeaters, particularly the western spinebill, which can access the nectar with its long curved bill, and the silvereye, which punctures the flower tube. The most commonly cultivated Adenanthos species in Australia, it has a long flowering period and attracts honeyeaters to the garden. It is harvested for the cut flower industry.
Common names for this species include basket flower, glandflower, jugflower and stick-in-the-jug. In the King George Sound vicinity the Aboriginal name Cheeuk is sometimes used.
Abundant and widespread the species occurs in coastal regions of Southwest Australia, from Gingin and Muchea north of Perth south to Augusta and east along the south coast to Green Range, east of Albany. It also occurs in the Stirling Range, a possible disjunction; and at Narrogin, a certain and substantial disjunction. Nelson tentatively explains these disjunct populations in terms of natural climate fluctuations: during times of higher rainfall, the distribution of A. obovatuswould have been much more extensive.
