ABSTRACT:
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.
