This is a genus of about 200 species of
herbaceous perennials, succulents and
shrubs. They are native to areas in South Africa.
sold as a bedding plant and used as an
annual in the home garden, members of this
genus are often called by the misnomer,
geranium. They differ from plants in the
Geranium, due to the fact that
Pelargoniums have a calyx spur that is
united to the pedicel. This trait is very
minor and can be seen by making a
longitudinal section of the pedicel.
The name confusion comes because Carl
Linnaeus originally lumped Pelargoniums
into the genus Geranium but a later
taxonomist separated them out into their own
