Double Zonal Pelargoniums originated from crossing P. zonale with P. inquinans and is probably the most popular and widely grown Pelargonium in the world. The double form was a spontaneous sport occurring in the 19th century. They have a wide range of garden uses - pots and containers, traditional bedding, houseplants, conservatories and the show bench. The range of colours and plant shapes and size is infinite. They are easy to propagate and quick to grow making them still as popular today as they have ever been.
