Abstract

A new cultivar of Erigeron named ‘Spindrift’ that is distinguishable by medium green foliage, a compact mounding habit and small daisy-like flowers that range in color from dark purple to lilac-pink and white. In combination these traits set ‘Spindrift’ apart from all other existing varieties of Erigeron known to the inventor.

Description

Genus: Erigeron.
Species: karvinskianus.
Denomination: ‘Spindrift’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Santa Barbara daisy and is an herbaceous perennial that is grown for use as an ornamental landscape and container plant. The new invention is known botanically as Erigeron karvinskianus and will be referred to hereinafter by the cultivar name ‘Spindrift’. Erigeron is in the family Compositae in which the commonly referred to “flower”, is actually the inflorescence, and made up of smaller ray flowers and disc florets. For ease of clarification the common term “flower” is used herein to describe the inflorescene.
‘Spindrift’ is an induced mutation that was bred by the inventor in January 1998 in a cultivated area of Victoria, Australia. In March 1997 the inventor treated ten Erigeron karvinskianus plants with Colchicine. Colchicine was used to change the chromosome count of the plant. Dwarfing can be a side effect of the chemical and was critical to the breeding process. In January 1998 the seed from these plants was collected and sown. The inventor selected ‘Spindrift’ in 1998, from the seedlings that resulted, based on its compact growth habit. The female parent plant is Erigeron karvinskianus (unpatented) and the male parent plant is Erigeron karvinskianus. ‘Spindrift’ differs from the parent plant in growth habit and fertility.
‘Spindrift’ is a ground cover and container plant that exhibits a compact mounding habit with small daisy-like flowers that bloom year round. Flowers exhibiting the colors of white, pink-lilac and dark purple-rose are all individually present on an individual plant. ‘Spindrift’ is hardy to minus 2° Centigrade and cultural requirements include full sun to light shade and moist well-draining soil. The distinguishing characteristics of ‘Spindrift’ are habit and low fertility. The closest comparison plant is the parent plant Erigeron karvinsiana. ‘Spindrift’ is distinguishable from the parent plant by growth habit and low fertility.
The first asexual reproduction of ‘Spindrift’ was carried out by the inventor in 1998 in a cultivated area of Melbourne, Australia. The method used was softwood cuttings. Since that time subsequent generations have been determined stable and true to type.
SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and represent the distinguishing characteristics of the new Erigeron cultivar. These traits in combination distinguish ‘Spindrift’ from all other existing varieties of Erigeron known to the inventor. ‘Spindrift’ 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. Erigeron ‘Spindrift’ is an herbaceous perennial exhibiting a compact, mounding growth habit.
2. Erigeron ‘Spindrift’ produces small daisy-like flowers that exhibit the colors dark purple-rose, lilac-pink, and white all individually present on an individual plant.
3. Erigeron ‘Spindrift’ exhibits low fertility.
4. Erigeron ‘Spindrift’ exhibits medium-green foliage.
5. Erigeron ‘Spindrift’ is 16 cm. in height and 40 cm. in width in a 2-litre container.
6. Erigeron ‘Spindrift’ is floriferous and moderately vigorous.
7. Erigeron ‘Spindrift’ continues blooming year round.
8. Erigeron ‘Spindrift’ is hardy to minus 2° Centigrade.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying color drawings illustrate the overall appearance of the new Erigeron variety ‘Spindrift’ showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The drawings were made in September 2002 of plants grown out-of-doors in a cultivated area of Breaside, Victoria, Australia. The plants were 2 years old at the time and grown out-of-doors in the ground.
The drawing on sheet 1 illustrates the entire plant in bloom from a front perspective.
The drawing on sheet 2 illustrates a close-up view of the flowers. Colors in the photographs may differ from the color values cited in the detailed botanical description, which more accurately describes the actual colors of the new variety ‘Spindrift’. Drawings were made using conventional techniques and although flower and foliage colors may appear different from actual colors due to light reflectance, they are as accurate as possible by conventional photography.
BOTANICAL DESCRIPTION OF THE PLANT
The following is a detailed botanical description of the new Erigeron variety ‘Spindrift’. Observations, measurements, values and comparisons were taken in Arroyo Grande Calif. from 6-month-old plants grown out-of-doors in 2-litre containers. Color determinations are made in accordance with The 2001 Royal Horticultural Society Colour Chart from London England, except where general color terms of ordinary dictionary significance are used. The Compositae family, under which Erigeron falls, exhibits an inflorescence which is commonly referred to as the “flower”. In actuality smaller ray flowers and disc florets make up the inflorescence. For ease of clarification the common term “flower” is used here to designate a category of description. Under this category is the detailed botanical description of the parts of the inflorescence, which is commonly referred to as the flower on this plant.
