Shrub rose plant named ‘INTERhappy’

Abstract

A shrub rose plant named ‘INTERhappy’, characterized by a combination of dark green, glossy foliage; flowers that are a yellow-orange color; and a compact form, particularly suitable as a groundcover.

Description

Genus and Species: Rosa hybrida.

Variety Denomination: ‘INTERhappy’.

Origin of the Invention

The present invention relates to a new and distinct variety of a shrub rose plant named ‘INTERhappy’ which was originated by me as a cross of a pollen parent and a seed parent.

Background of the Invention

The primary objective of this breeding was to produce a new shrub rose variety.

Brief Summary of the Invention

The objective was substantially achieved as evidenced by a new shrub rose having a unique combination of characteristics that are outstanding in the new variety and that distinguish the new variety from its parents and other varieties of which the inventor is aware including dark green, glossy foliage, flowers that are a yellow-orange color (apricot/pink), and a compact form, particularly suitable as ground cover.

Asexual reproduction of this new variety by softwood cuttings, as performed at Wasco, Calif., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

Comparison with Parents

‘INTERhappy’ has a more compact growth than the seed parent, which also had an orange flower color. The pollen parent had also compact growth, as ‘INTERhappy’, but the flower color of the pollen parent was pale yellow.

Comparison with Similar Variety

The inventor is not aware of any similar varieties with the flower color of ‘INTERhappy’.

BRIEF DESCRIPTION OF THE ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.
