USPP30507P2 - Coleus plant named ‘SAKCOL022’ - Google Patents

Abstract

A coleus plant particularly distinguished by small leaves having a pink and dark burgundy inner leaf color and green margins, is disclosed.

Description

Genus and species: Solenostemon sp.

Variety denomination: ‘SAKCOL022’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of coleus, botanically known as Solenostemon sp., and hereinafter referred to by the variety name ‘SAKCOL022’.

‘SAKCOL022’ originated from the open pollination of 8 unpatented proprietary lines crossed pollinated in October 2014 in Kakegawa, Japan. The breeder put breeding materials ‘14P-202’, ‘14P-203’, ‘14P-205’, ‘14P-210’, ‘14P-211’, ‘14P-212’, ‘14F-19’, and ‘14F-20-2’ in a cage. Bees then crossed them at random. The breeder harvested 1,200 seeds from ‘14P-211’. These seeds were composed of hybrid seeds and self-pollinated seeds.

The seeds obtained from the ‘14P-211’ plant were sown and a single plant selection designated ‘L2015-CO372’ was selected for its multi-colored leaf pattern with a pink and dark burgundy inner leaf color and green margins with mounding plant habit with small leaves. The breeder confirmed that ‘L2015-CO372’ was fixed and stable. ‘L2015-CO372’ was subsequently named ‘SAKCOL022’.

The new plant was first asexually propagated from October 2015 to April 2016 in Japan and has been asexually reproduced by vegetative cuttings for almost three years in Japan. The present invention has been found to retain its distinctive characteristics through successive asexual propagations by vegetative cuttings.

‘SAKCOL022’ has not been made publicly available or sold more than one year prior to the filing date of this application.

SUMMARY OF THE NEW PLANT

The following are the most outstanding and distinguishing characteristics of the new variety when grown under normal horticultural practices in Salinas, Calif.

• • 1. Small leaves; and
  • 2. Pink and dark burgundy inner leaf color and green margins.

DESCRIPTION OF THE PHOTOGRAPHS

This new coleus plant is illustrated by the accompanying photographs which show the overall plant habit, foliage, and flowers of a plant aged 3 months old. The colors are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘SAKCOL022’. The data which defines these characteristics were collected from plants grown three months from transplant into 4-inch pots from rooted cuttings in Salinas, Calif., under greenhouse conditions. Color references are to The Royal Horticultural Society Colour Chart, 4^th edition. Anatomic labels are from The Cambridge Illustrated Glossary of Botanical Terms, by M. Hickey and C. King, Cambridge University Press.

• Environmental conditions for plant growth: The terminal 1.0 to 1.5 inches of an actively growing stem was excised. The vegetative cuttings were propagated for five to six weeks. The base of the cuttings were dipped for 1 to 2 seconds in a 1:9 solution of Dip 'N Grow (1 solution: 9 water) root inducing solution immediately prior to sticking into the cell trays. Cuttings were stuck into plastic cell trays having 98 cells, and containing a moistened peat moss-based growing medium. The cuttings were misted with water from overhead for 10 seconds every 30 minutes until sufficient roots were formed. Rooted cuttings were transplanted and grown in 20 cm diameter plastic pots in a glass greenhouse located in Salinas, Calif. Pots contained a peat moss-based growing medium. Soluble fertilizer containing 20% nitrogen, 10% phosphorus and 20% potassium was applied once a day or every other day by overhead irrigation. Pots were top-dressed with a dry, slow release fertilizer containing 20% nitrogen, 10% phosphorus and 18% potassium. The typical average air temperature was 24 degrees C.
