Campanula Plant Named ‘Blue-Eyed Blonde’

Abstract

A new and distinct Campanula plant characterized by yellow to yellow green foliage, large, blue bellflowers in upright and decumbent stalks, a compact, low habit, and excellent vigor.

Description

Botanical denomination: Campanula persicifolia.

Variety designation: ‘Blue-Eyed Blonde’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Campanula and given the cultivar name of ‘Blue-Eyed Blonde’. Campanula is in the family Campanulaceae. The new cultivar originated from planned breeding program to produce a blue flowering, yellow leaf Campanula persicifolia. The original parent plant used was Campanula persicifolia ‘Double Blue’ (an unpatented plant) as the seed parent and Campanula persicifolia ‘Kelly's Gold’ (an unpatented plant) as the pollen parent. Several generations were needed to produce yellow leaf, blue-flowered offspring. ‘Blue-Eyed Blonde’ was selected as the best seedling for vigor, broad leaves, and large attractive blue flowers. Compared to the seed parent, Campanula persicifolia ‘Double Blue’ the new cultivar has gold rather than green leaves and single blue rather than double blue flowers. Compared to the pollen parent, Campanula persicifolia, ‘Kelly's Gold’, the new cultivar has large blue flowers rather than medium size white tinted blue flowers.

SUMMARY OF THE INVENTION

This new Campanula is distinguished by:

• • 1. yellow to yellow green foliage,
  • 2. large, blue bellflowers in decumbent and upright stalks,
  • 3. a compact, low habit, and
  • 4. excellent vigor.

To the inventor's knowledge, this combination of yellow foliage and blue flowers is new and unique in Campanula persicifolia.

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 tissue culture using standard micropropagation techniques with terminal 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 change with variations in environment without a change in the genotype of the plant.
