What is Geranium 'Rozanne'?

Geranium 'Rozanne' (Rozanne© Gerwat) - to give her her full botanical name - is a Hardy Geranium. Hardy Geraniums are perennial plants that live for many years, dying down each autumn to re-emerge bigger and better the following spring.

Although they are part of the same Geraniaceae family, Hardy Geranium are very different to Pelargoniums, which are also commonly referred to as Geraniums but are half-hardy plants that in cooler regions tend to be used in the same way as annuals.

So many flowers, for so long!

Geranium 'Rozanne' is the perennial with the profuse flower power of an annual, producing a continual stream of large violet-blue flowers from May right through to the first hard fall frosts. No other Hardy Geranium puts on such an extended show.
