What does a Pelargonium look like? Pelargoniums sport five petals, just like the cranesbill. However, they differ in that the two upper petals are a different shape and size from the rest, giving it an asymmetrical appearance. Unlike the true hardy geranium, which generally lays low and wide, pelargoniums have tall stems that become woody as they age.
Pelargoniums are not thirsty plants so water moderately from spring to summer, taking care that the compost doesn’t become too wet. Open windows or vents in a conservatory or greenhouse in summer to be sure of good air flow. Water only sparingly in winter, so that the compost has time to dry between waterings.
Pelargoniums, commonly known as ‘geraniums’, are very ornamental perennial plants producing lots of extremely colourful flowers for months on end. Some start to flower in spring, but mainly from early June to the first severe frosts of autumn. If grown indoors they can flower all year round.
