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).
