The case for using the correct specifications that do identifyGeranium and
Pelargoniumcultivars universally. There are a number of clubs and commercial plant
producers out of step with the correct family naming of the herbaceous plants they are
growing, showing or producing. This is a practice that should be changed by those who
want to be up to date and correct in the botanical and nomenclatural sense.
When is a geranium not a geranium? Fundamentally it is when it cannot be classified
to meet the specifications to be in GenusGeranium. This is the essential requirement.
The same is required for other Genera that are grouped in Family Geraniaceae.
Are you using the correct family name for the plants you are growing or marketing?
Two definitions for Geraniaceae have been found.
A. Geraniaceae is a family of geraniums. This definition is misleading.
B. Geraniaceae is a family of herbaceous plants. A definition that is preferable as this allows
for the many genera within this family to be classified with specific characteristics to enable
each genera to be identified and separated.
Geraniaceae is composed of a number of Genera. The 3 main genera that are being grown
by Geranium and Pelargonium Club members are GenusGeranium, Genus Pelargonium and
GenusErodium - each of these Genera have specific characteristics to be included into their
Another problem is: All articles of reference toPelargoniums as ‘Geraniums’ need to be
updated or not used as this is very misleading information, particularly for anyone being
introduced to the world ofPelargoniums that are incorrectly called Geraniums. This
contradiction is very damaging to any intention of getting in step with the correct identification
used by most of the world’s pelargonium growers.
Think about it and please discuss with friends who grow or show these plants
