Ivy Geranium (Pelargonium peltatum) is a trailing tender perennial native to South Africa, named for its glossy, ivy-shaped leaves and its sprawling, cascading habit. Unlike upright zonal geraniums, it spills gracefully over the edges of pots, making it a favourite for hanging baskets, window boxes and balcony railings.
It bears showy clusters of single or double flowers in shades of pink, red, mauve, lavender and white, blooming heavily through the cooler months. In India it performs best in hill stations and during the winter season in the plains, where mild temperatures and bright light bring out its best flowering.
Easy to grow and drought-tolerant once established, it rewards gardeners with months of colour and is readily propagated from stem cuttings.

Uses
<p>Ivy Geranium is grown almost entirely as an ornamental for its long-lasting, colourful flowers.</p><ul><li>Hanging baskets, window boxes and tall pots where its trailing habit can cascade.</li><li>Balcony and terrace railings, a favourite in hill-station gardens like Ooty, Kodaikanal and Shimla.</li><li>Ground cover or edging in cooler regions.</li><li>Seasonal winter colour in pots across the Indian plains.</li></ul>
Growing tips
<p>In the plains, treat it as a cool-season plant: plant out from October-November for flowering through winter and spring, and move pots to a shaded, well-ventilated spot before the harsh summer (April-June).</p><p>In hill stations it can flower for much of the year. Always use a free-draining mix and terracotta pots to prevent root rot during the monsoon, and shelter plants from heavy rain. Pinch young plants and deadhead regularly to keep blooms coming.</p>
