|'Sefton' is a regal cultivar bearing clusters of cerise-red flowers, each petal with deep red fine markings.
This plant is commonly called a geranium, which can be confusing. The genus is Pelargonium, though there is a completely different group of plants with the genus name Geranium, which are commonly called Cranesbills. Remove dead flowers to promote new growth. Excellent container or border plant. Good houseplant.
