Regal pelargonium

Appearance

Additional descriptive terms include;

Fancy leaf – Leaves with marked variations in colour
Decorative pelargoniums (Decoratives) – Descendants of older, less compact, smaller-flowered varieties that are more suited to outdoor conditions. These have smaller flowers than Regal, but are otherwise similar. e.g. ‘Royal Ascot’
Miniature – Flowers and leaves similar to Regal, but miniature in form, with compact growth. Other terms include “Pansy Geraniums” or “Pansy Pelargoniums”. e.g. ‘Lara Susan’
Oriental pelargoniums – The result of crosses between Regals and members of the Angel group (see below). Some have bicolour foliage.

Naming

In the United States they are often known as the "Martha Washington" or ‘"Lady Washington" pelargoniums. They are grown primarily for the beauty and richness of their flower heads, which are large. Most of those cultivars grown currently are the result of hybridization over the last 50 years. They are very short-jointed and compact, which results in their requiring very little work in order to create a floriforous and well-rounded plant. Flowers are single, rarely double, in mauve, pink, purple or white. They have rounded, sometimes lobed or partially toothed (serrated) leaves, unlike the Zonal groups, without any type of zoning.
