What is a geranium?
Geraniums are popular perennial flowering plants. Geranium is a common name that refers to two genera - Geranium and Pelargonium. True geraniums are hardy, while Pelargoniums are tender perennials that are often treated as annuals in the UK climate. Both are referred to as ‘geraniums’ by most gardeners.
The first tender Pelargonium arrived in England in the 17th century from South Africa, while many hardy Geraniums are native to the UK. Plant both types of geraniums in garden borders, pots and hanging baskets for a sizzling floral display.

How to grow geranium plants?
The easiest way to grow geraniums and pelargoniums is from plug plants that can be planted straight into the garden or into pots.
Hardy geraniums can be grown from seed on a sunny windowsill or planted straight into the garden as bare root. Pelargoniums are best grown from plug plants or cuttings - they hybridise readily and can produce seed that is not true.
Pelargoniums don’t like frost and will need to be sheltered indoors over winter. Hardy geraniums can overwinter in the garden, all they need is cutting back mid autumn to keep them tidy. Divide hardy geraniums three to five years after planting, to produce new plants for the rest of the garden.
What are the best geranium flowers?
The best geranium flowers are produced by zonal Pelargoniums which also have eye catching leaf patterns. Grow regal Pelargoniums for blowsy large petals, and vibrant colours. Trailing Pelargoniums work well in hanging baskets - read our three step guide on how to plant up hanging baskets for the best display.
Wildlife gardener? Bees love the blue dish shaped flowers of hardy geraniums. For pots, try scented leaf Pelargoniums for sensory stimulation and delicate flower displays.
How long do geraniums flower?
Geraniums produce flowers until the first frost, usually at the end of autumn. Feed geraniums with fertiliser and deadhead regularly during the growing season to promote flowering. Try planting Fuchsias, Begonias and Petunias alongside geraniums for a colourful summer display.
Why are my geranium leaves turning yellow?
Hardy geranium leaves can turn yellow when they need water. Water your geranium plants more often to prevent leaf yellowing. For more information on geranium problems, read our practical troubleshooting your geraniums guide.
