Abstract
A new and distinct Coreopsis plant named ‘Imperial Sun’ characterized by daisy-type inflorescences that grow to 4.5 cm in diameter, inflorescences that are bright yellow, plants hardy to Zone 6, maybe lower, grass green foliage on short stems, flowering for the whole summer, a low, mounding habit, and excellent vigor.
Description
Latin name: Coreopsis verticillata hybrid.
Varietal denomination: ‘Imperial Sun’.
The present invention relates to a new and distinct Coreopsis and given the cultivar name ‘Imperial Sun’. Coreopsis is in the family Asteraceae. This new cultivar originated from a controlled breeding program to produce hardy compact Coreopsis verticillata types. The new cultivar originated as an F2 interspecific hybrid seedlings of proprietary unnamed parents. This new cultivar of Coreopsis is a herbaceous perennial to be grown for landscape and container use in a sunny site.
Compared to the parent plants, the new cultivar has a shorter and denser habit and larger flowers.
Compared to Coreopsis verticillata ‘Zagreb’, an unpatented plant, the new cultivar has larger inflorescences and a shorter habit.
The following traits have been repeatedly observed and are determined to be the unique characteristics of the new variety. These characteristics in combination distinguish Coreopsis ‘Imperial Sun’ as a new and distinct cultivar:
-
- 1. daisy-type inflorescences that grow to 4.5 cm in diameter,
- 2. inflorescences that are bright yellow,
- 3. plants hardy to Zone 6, maybe lower,
- 4. grass green foliage on short stems,
- 5. flowering for the whole summer,
- 6. a low, mounding habit, and
- 7. excellent vigor.
This new cultivar has been reproduced only by asexual propagation (cuttings and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by cuttings and tissue culture using standard micropropagation techniques with terminal and lateral shoots, as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.
The following is a detailed description of the new Coreopsis cultivar based on observations of ten-month-old specimens growing in one-gallon containers in full sun in Canby, Oreg. Canby is Zone 8 on the USDA Hardiness map. Temperatures range from a high of 95° F. in August to 32° F. in January. Normal rainfall in Canby is 42.8 inches per year. The color descriptions are all based on The Royal Horticultural Society Colour Chart, 5th edition.
