Pelargonium plant named ‘Sarah Don’

Abstract

A new cultivar of Pelargonium plant named ‘Sarah Don’ that is characterized by a dense mounding habit, golden-yellow and lime-green variegated foliage, and mauve flowers with dark purple-pink markings. In combination these traits set ‘Sarah Don’ apart from all other existing varieties of Pelargonium known to the inventor.

Description

Genus: Pelargonium.

Species: domesticum.

Denomination: ‘SARAH DON’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of geranium that is grown as an ornamental for its golden-yellow and lime-green variegated foliage. The new cultivar is known botanically as Pelargonium×domesticum and will be referred to hereinafter by the cultivar name ‘Sarah Don’.

‘Sarah Don’ is a naturally occurring branch sport that was discovered by the inventor at the base of a commercially grown Pelargonium ‘Darmsden’ (unpatented) in a cultivated area of Hampshire, England. On Nov. 12, 1998 the inventor selected ‘Sarah Don’ for its unique golden-yellow and lime-green variegated foliage. ‘Sarah Don’ is distinguishable from the parent plant by its leaf color and variegation. The parent Pelargonium ‘Darmsden’ does not exhibit any variegation.

‘Sarah Don’ is from a group of Pelargonium commonly referred to as Angel Pelargonium. Within this group the flowers are smaller and more numerous than in any other group of Pelargonium.

‘Sarah Don’ was first asexually propagated by the inventor in 1998 in a cultivated area of Hampshire, England. The method used for asexual propagation was vegetative cuttings. Since that time the characteristics of the new cultivar have been determined stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the distinguishing characteristics of the new cultivar ‘Sarah Don’. In combination these traits set ‘Sarah Don’ apart from all other Pelargonium known to the inventor. ‘Sarah Don’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions, however, without any variance in genotype.

1. Pelargonium ‘Sarah Don’ exhibits golden-yellow and lime-green variegated foliage.

2. Pelargonium ‘Sarah Don’ flowers profusely and exhibits mauve flowers with dark purple-pink markings.

3. Pelargonium ‘Sarah Don’ grows to 60 cm. in height and 80 cm. in width at maturity.

4. Pelargonium ‘Sarah Don’ exhibits a dense, naturally determining, mounding habit.

5. Pelargonium ‘Sarah Don’ is hardy to USDA Zone 8.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings illustrate the overall appearance of the new cultivar ‘Sarah Don’ showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The plants in the photographs were grown in Arroyo Grande, Calif. in one-litre containers. The plants were 12-months-old at the time and grown in a greenhouse. They were photographed in July.

Sheet 1 illustrates an entire plant from a side perspective. Sheet 2 shows a close-up view of the flowers and the foliage. All photographs were made using conventional techniques and although colors may appear different from the color values cited in the detailed botanical description, due to light reflectance, they are as accurate as possible by conventional photography. The detailed botanical description accurately describes the actual colors of the new cultivar ‘Sarah Don’.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Pelargonium named ‘Sarah Don’. Information was collected in Arroyo Grande Calif. from 12-month-old plants grown in a greenhouse in one-litre containers. The color determinations are in accordance with The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to other Pelargonium.
