Citronella Pelargonium Overview

Pelargonium citronellum is a strongly scented herb that releases a lemony fresh scent when touched. This low maintenance, evergreen plant is easy to grow and makes for an interesting garden subject with its attractive, scented leaves and clusters of pink-purple flowers during the spring and summer. Lemon-Scent Pelargonium is perfect for growing in containers, especially close to windows and entrances where the lemon scent can be enjoyed often. Due to its natural insecticidal properties it repels pests, making it a wonderful companion plant. This plant does best in full sun, well-draining soil that is kept moist throughout the year. If you are situated in a region where winter temperatures regularly drop below minus figures, Pelargonium citronellum will need some winter protection. You can easily take cuttings to overwinter on windowsills or in heated greenhouses. Regular light pruning will help keep this beautiful plant looking at its best and prevent it from getting too leggy. It is often grown as a culinary herb or to infuse iced teas and desserts. You could also try drying the scented leaves to be used as potpourri.
