There is often confusion between pelargoniums and geraniums. Michael Perry from Thompson and Morgan showed Ken Crowther some of the pelargoniums and geraniums they grow and highlights the differences between the two.
The main differences are petal shape: pelargoniums (Left) have 5 petals with the top two usually a different shape or size. Pelargoniums aren’t as hardy outdoors as the geranium and are unlikely to survive the winter.
A geranium (right) is of the same family as pelargoniums. It has 5 symmetrical petals and is a hardy perennial. This means that a geranium will return each year and is often raised outdoors in a bed.
Michael says that seed raised plug plants are very cost-effective and a cheaper way to buy geraniums. A zonal plant is generally raised from a cutting and will be more expensive to produce.
