USPP34144P2 - Rhaphiolepis plant named ‘SMNRICS’ - Google Patents

Abstract

A new and distinct cultivar of Rhaphiolepis plant named ‘SMNRICS’ is disclosed, characterized by abundant, bright pink flowers, and glossy, dark green leaves. Plants have a compact, ground-hugging growth habit. The new variety is a Rhaphiolepis, typically produced as an ornamental plant.

Description

Latin name of the genus and species: Rhaphiolepis indica.

Variety denomination: ‘SMNRICS’.

BACKGROUND OF THE INVENTION

The new Rhaphiolepis cultivar is a product of a planned breeding program conducted by the inventor. The objective of the breeding program was to produce new Rhaphiolepis cultivars with increased flower number, and compact, spreading habits. The open-pollination resulting in this new variety was made in 2010, at a commercial nursery in Grand Haven, Mich.

The parents cannot be identified as this new selection resulted from an open pollination in which seed was bulk collected. The new cultivar was found and selected by the inventor in 2015 at the same nursery in Grand Haven, Mich.

Asexual reproduction of the new cultivar ‘SMNRICS’ was first performed in 2015 in Grand Haven, Mich., by softwood cuttings. Subsequent propagation has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘SMNRICS’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SMNRICS’. These characteristics in combination distinguish ‘SMNRICS’ as a new and distinct Rhaphiolepis cultivar:

• • 1. Compact growth.
  • 2. Dense branching.
  • 3. Somewhat spreading, ground-hugging habit.
  • 4. Glossy, dark green leaves.
  • 5. Reblooming.

PARENT COMPARISONS

Parental comparisons are unavailable, as both parents are unidentified.

COMMERCIAL COMPARISONS

Plants of ‘SMNRICS’ are similar in some horticultural characteristics to the variety Rhaphiolepis ‘Eleanor Tabor’, unpatented. The new variety, however, differs in the following:

• • 1. The new variety has a slightly spreading habit, while this comparator has a less spreading and more upright habit.
  • 2. The new variety has an abundance of pink flowers, while this comparator produces less flowers.
  • 3. Flowers of the new variety are a darker pink than flowers of this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

‘SMNRICS’ is illustrated by the accompanying photographs which show the plant's form, foliage, and inflorescences. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new hybrid Hydrangea. Age of the plants photographed is between 2 to 3 years.

FIG. 1 shows a container grown flowering plant of ‘SMNRICS’ grown outdoors in Grand Haven, Mich. at about 2 years of age.

FIG. 2 shows the mature inflorescences of a container-grown plant of ‘SMNRICS’, grown in Grand Haven, Mich.
