Giant Geranium

Name: Geranium maderense (Geraniaceae)
Common Names: Giant Cranesbill, Giant Geranium


Flower

This evergreen aromatic biennial is the largest geranium. Everything about it is large. The deeply cut snowflake shapped leaves grow from thick stems that later support the plant when the leaves die. On large plants leaves can grow to 40cm across! That in itself is showy and is worth growing this plant for.

The huge flower head appears in Spring and grows to 150cm tall and 80 cm across, with hundreds of pinky-purple flowers. A truly amazing sight.

Geranium maderense self seeds readily and is perfect for the cottage garden. It is only half-hardy and will be killed by heavy frost. It is suitable for milder areas or plant in a pot and over winter in a conservatory. When the weather warms in the Spring, bring the plant out after the last frost to flower.
