Floribunda rose plant named ‘PNKTER’

Abstract

PNKTER is a new and distinct Rosa hybrid plant which is characterized by the combination of a bushy growth habit with an abundance of doubled-type pink flowers born on terminal corymbs, strongly perfumed flowers, very high resistance to blackspot and powdery mildew diseases, and the stability of these characteristics from generation to generation.

DETAILED BOTANICAL DESCRIPTION

(3) The following is a detailed botanical description of a new and distinct Rosa hybrid plant known as PNKTER. Plant observations were made on a container-grown plant produced outdoors in Sarasota, Fla. Unless indicated otherwise, the descriptions disclosed herein are based upon observations made of a six month old PNKTER plant, grown in a three gallon nursery container. The plant was grown in full sun, provided regular manual irrigation, and fertilized approximately every three months with a slow-release granular fertilizer. Fungicide and insecticides were applied in both preventative and curative applications, as needed. Observation data were recorded in the September of 2019.

(4) Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. PNKTER has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 1986 edition except where common terms of color are used.
