Confusingly known as geraniums, pelargoniums are in the same plant family as hardy geraniums, but fall into a different genus and bear no resemblance to them at all. They are normally grown as annual bedding plants although they can be overwintered indoors, and are prized for their bright summer flowers and attractive, often fragrant, foliage.

Pelargoniums come in a variety of forms, and most belong to one of the following six horticultural groups: Angel, Ivy-leaved, Regal, Scented-leaved, Unique and Zonal. All thrive in full sun and do best when grown in a sheltered, sunny spot.

Pelargonium ‘Romeo’ is a compact Regal pelargonium with intense dark red flowers in contrast with fresh green leaves. It’s perfect for growing in a large pot on a sunny patio, as a house plant in the conservatory or window sill, or at the front of a sunny border.

For best results, feed Pelargonium ‘Romeo’ with a high potash fertiliser during summer and deadhead spent blooms regularly. Bring plants indoors for winter.
