A complex hybrid group referred to botanically as P. ×domesticum, the hybrid background involving the species P. cucullatum, P. grandiflorum, P. angulosum, P. fulgidum and probably others.
Pelargoniums in this group have fleshy stems and leaves that are kidney-shaped to roundish or triangular, with 3 lobes, large teeth and/or wavy edges, sometimes cupped or folded. Flowers in large, erect clusters.
The group was derived in the 19th century and called 'regal' because its members were cultivated in the glasshouses of English royalty.
They are prone to infestations of green- and whitefly.
