Interspecific Geraniums

The interspecific geranium like the famous Calliope geraniums and Champion geraniums, combines the qualities of its two parents, the ivy-leaved geranium or pelargonium and the zonal type. It is a bushy plant, 35 to 50 cm (14 to 20in) high, robust, vigorous, and with excellent resistance to diseases, bad weather, and drought, flowering from May until the first frost. The interspecific geranium forms sturdy stems like zonal geraniums or pelargoniums, but flexible like ivy-leaved ones. Very floriferous and with rapid growth, it offers vigorous vegetation and has peltate, circular leaves, often spotted with brown, slightly fleshy, and aromatic. The latest generation of interspecific geraniums, like the 'TwoinOne', offer single to double flowers in a wide range of colours, from white to red, purple, and pink. They can be planted in pots or in the ground, in spring after the last frost. They are not hardy and should be overwintered frost-free.
