Pelargonium is a genus of flowering plants which includes about 200 species of perennials, succulents, and shrubs, commonly known as geraniums or storksbills. Confusingly, Geranium is the correct botanical name of a separate genus of related plants often called Cranesbills. Both genera are in the Family Geraniaceae. They are drought and heat tolerant, but can tolerate only minor frosts. Some species are extremely popular garden plants, grown as bedding plants in temperate regions.

Pelargonium reniforme is an attractive showy plant with flower colours varying from pink to magenta. Pelargonium reniforme is a small, upright perennial shrublet with tuberous roots. It generally attains a height of 300 – 400 mm, but has been known to reach a height of 1 m. In contrast to the soft and downy flowering branches, the short main stem is often covered with the remains of old stipules. Leaves are reniform (kidney-shaped) or cordate (heart-shaped) with crenate or finely lobed margins and are usually 20 – 30 mm in diameter. Leaves on the main stem are usually larger than those of the flowering stems. The presence of matted hairs give the leaves a velvet-like texture and greyish-green colour. The lower surface of the leaves presents a thicker hairiness and more distinct venation than the upper surface. Long petioles typify this pelargonium, with awl-shaped stipules found at their bases. Plants flower throughout the year. Flowers are borne in 3- or more-flowered umbel-like inflorescences. Colours vary from pink to magenta with a darker spot and stripes on the upper 2 petals. Six or seven fertile stamens are present.
