Pelargonium-Zonale – hybr

This hybrid is descended chiefly from the South African P. zonale. The principal characteristics of this sub-shrub are the upright habit of growth and the rounded, heart-shaped, faintly lobed leaves, softly hairy and with a pronounced ^darker stripe on the upper side. The inflorescences may have as many as 25 flowers, varying in colour from pink to red, occasionally also white. P. crispum, P. graveolens, P. capitatum and P. tomenosum have fragrant leaves.

Conditions for growing are the same for all Pelargonium species, varieties and cultivars. A suitable growing medium is a mixture of frame soil, leaf mould and compost. Transfer to a cool place in winter, about 10°C (50° F), and restrict watering. Water regularly during the growth period, as drying out even once will cause the leaves to drop. Feed with organic fertilizer. Propagate by means of tip cuttings or side shoots in March or August. Allow them to dry for a few hours before inserting in compost.

Pelargonium- Grandiflorum – hybr

Regal Pelargonium is also a hybrid obtained by many crossings; its parentage includes P. cucullatum, P. cordatum and P. grandiflorum. The stems turn woody quite soon. The leaves are only faintly lobed, sharply toothed, and when rubbed between the fingers do not give off as strong a scent as those of the preceding species. The flowers are extremely large, about 5 cm (2 inch) across, and coloured white, pink, violet or red. The petals have prominent dark patches.

Pelargonium-Peltatum – hybr.

Ivy-leafed Geranium has typical prostrate, faintly angled stems that are usually glabrous. The leaves are long-stalked, usually five-lobed, fleshy and very glossy. They are mostly glabrous, but very sparingly hairy on the margin. The flowers may be simple, semi-double or double and variously coloured – for example white, pink, violet or red, depending on the cultivar.
