Pelargonium- Geranium

Non-hardy plant, better known as an indoor plant.


Geraniums are used on a large scale in window-boxes, but also as bedding plants. They require full sun and the reason why they do so well in window-boxes is that they need little water.


Use potting soil in boxes and containers; in the garden any not too wet soil is acceptable.


A number of varieties can be sown under glass.from mid winter onwards; otherwise take cuttings in late summer; keep them frost free in winter.
