The hill hibiscus (Hibiscus sturtii) is a rigid plant that grows both outwards (horizontal to the ground) and upwards (2) (3). Its broad, oval-shaped leaves are thick and soft, and its flowers vary in colour being either pink, purple or white (2) (4). Each flower has a diameter of approximately six centimetres (2). The seeds are contained within hairy, spherical, one-centimetre capsules (1) (2).
There are five recognised varieties of the hill hibiscus: Hibiscus var. grandiflora, Hibiscus var. sturtii, Hibiscus var. muelleri, Hibiscus var. campylochlamys, and Hibiscus var. platychlamys (2) (3). These varieties differ slightly in appearance and geographical location within Australia (3).
The hill hibiscus flowers continuously throughout the year (6), but each individual flower only survives for up to two days (2). This species can survive in a range of soils and habitats (6), but is known to be sensitive to frost (7).
There is currently very little information available on the biology of the hill hibiscus.
