Description

''Persoonia hirsuta'' is a spreading to low-lying shrub that typically grows to a height of and has hairy branchlets leaves, flowers and fruit. The leaves are spatula-shaped to elliptic or linear to narrow oblong leaves, long and wide with the edges curved downwards or rolled under. The flowers are borne singly or in groups of up to ten on a rachis up to long that continues to grow into a leafy shoot after flowering. The

The two subspecies intergrade with each other from the lower Blue Mountains to within of the coast. Subspecies ''evoluta'' also hybridises with '' P. mollis'' subsp. ''nectens''. The fruit are adapted to be eaten by vertebrates, such as

The species occurs in fragmented small populations throughout its range and is threatened by urban development, clearing or degradation of bushland and too frequent bushfires and burning of bush. The European honeybee has been implicated in the decline of this and other species as it is suspected of being a poor pollinator of persoonia flowers.
