ABSTRACT:

Genus:
Pieris.
Species:
japonica.
Demonination: Katsura.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of lily-of-the-valley shrub and is a perennial that is grown for use as an ornamental landscape and container plant. The new invention is known botanically as
Pieris japonica
and will be referred to hereinafter by the cultivar name ‘Katsura’.
‘Katsura’ was discovered by the inventor in 1986 in a cultivated area of Kazakai, Hirata, Japan as a sport of the parent plant
Pieris japonica
(unpatented). The inventor is a collector of plants and author of numerous books on the subject of variegated plants, and observed the unique qualities of ‘Katsura’. The inventor selected ‘Katsura’ for its dark red new foliage, and rose-colored flowers. The wine-red foliage turns dark green.
The distinguishing characteristics of ‘Katsura’ are, continuous new growth through spring and summer, large glossy leaves that are wine-red in color before turning green, and rose-colored flowers. For best performance ‘Katsura’ requires semi-shade or sun, and slightly acidic soil with a ph of 4.5 to 5.5.
The closest comparison plant is
Pieris japonica
‘Red Mill’ (not patented). ‘Katsura’ is distinguishable from ‘Red Mill’ by flower color, dark red new growth, and large glossy leaves.
The first asexual reproduction of ‘Katsura’ was carried out by the inventor in 1989 in order to provide a plant for evaluation and further multiplication at the nursery firm Fa. C. Esveld in Boskoop, The Netherlands. 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
Pieris
cultivar. These traits in combination distinguish ‘Katsura’ from all other existing varieties of
Pieris
known to the inventors. ‘Katsura’ 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.
