Geranium 'Custard Cream'

Pelargonium, Zonal Geranium, Zonal Pelargonium

For many years the elusive yellow geranium has been the holy grail of the plant world. There are plenty of dark cream varieties but few have captured that true yellow colour. Pelargonium enthusiasts will love Geranium 'Custard Cream' for its buttery yellow blooms and fabulous vigour. Created by the world's leading geranium breeder, this superb zonal pelargonium deserves a prominent place in your patio containers and borders this summer. Height: 30cm (12"). Spread: 25cm (10").
Although technically perennial, Pelargoniums are only half hardy and therefore normally treated as annuals in the UK. However, with care, they may be overwintered in a frost free greenhouse.
