Geranium maderense 'Guernsey White'
Geranium maderense is usually magenta pink flowering this is a white form. But that aside this is no ordinary geranium it is a shrub forming short lived perennial from the island of Madeira. It is a large evergreen plant that will grow to a height and spread of 1m and will produce a mass of white flowers with magenta pink eyes all over the plant in the second or third year of growth which is very spectacular indeed. It has a wow factor even when it is not flowering with some really special dissected leaves all year round. It's best planted in full sun or very sunny aspect and is hardy to minus 4c so will need protection from severe frost and is best grown sheltered from severe winds also.
