Floribunda Rose plant named ‘Hadcup’

Abstract

A new and distinct rose cultivar of the Floribunda class characterized by having long lasting clusters of deep yellow flowers on clean stems without prickles and having a rapid rebloom cycle. The plant is upright and bushy and is of medium height, generally averaging about 1 meter. Stems are well covered with matte foliage. The plant is resistant to mildew, rust and blackspot.

Description

Botanical/commercial classification: Rosa hybrida/Floribunda Rose Plant.

The present invention relates to a new and distinctive cultivar of rose plant of the Floribunda class, which was originated by my crossing ‘Kika’ as the seed parent with the unamed seedling ((Basildon Bond×Arthur Bell)×Midas Touch)) as the pollen parent. The cultivar name of this plant is designated as ‘Hadcup’. It is being marketed under the commercial name of ‘Smooth Buttercup’.

Among the novel characteristics possessed by the new cultivar which distinguish it from:

• (a) All other cultivars of which I am aware are:
  • (1) Prickles are absent from any stems.
  • (2) Deep yellow flowers.
  • (3) Flowers in clusters of 3 to 14 blooms.
  • (4) Very consistent free bloomer.
• (b) Seed parent: White hybrid tea, few prickles.

Pollen parent: Medium yellow floribunda with prickles. Asexual reproduction of the new rose cultivar by budding onto the rootstock ‘Dr. Huey’, as performed at Wasco, Calif., shows that the aforementioned and all other distinctive characteristics come true to form and are established and transmitted through succeeding propagations.

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

The following is a detailed description of my new cultivar, with color terminology in accordance with The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in the color description herein refers to plate numbers in the aforementioned color chart, e.g. ‘Yellow Group 16A’ in Fan 1 of The Royal Horticultural Society Colour Chart.

  • • Seed parent.—IRAR registered: ‘Ortkee’; commercial name: ‘Kika’; Not patented.
