Bidens ferulifolia plant named ‘Bidcomtis’

Abstract

A distinct cultivar of Bidens plant named ‘Bidcomtis’ which is particularly distinguished by its very compact plant habit, short internodes, and golden yellow flowers. The new cultivar can perfectly be used in 10-12 cm pots and grown without growth regulators.

Description

Latin name of the genus and species of the plant claimed: Bidens ferulifolia.

Varietal denomination: ‘Bidcomtis’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new distinct cultivar of Bidens, botanically known as Bidens ferulifolia, native to South USA and Mexico.

The new cultivar is propagated by cuttings resulting from a seedling from Bidens ferulifolia cv. ‘Bidtis 1’ (U.S. Plant Pat. No. 12,280). Seed of ‘Bidtis 1,’ resulting from open pollination, was harvested in 1999 and a new variety ‘Bidcomtis’ was selected in 2000 as one of the plants of this population. This new plant is an annual. The new cultivar is a product of a planned breeding program conducted by the inventor in Enkhuizen, The Netherlands. The objective of the breeding program was to develop a compact Bidens variety. ‘Bidcomtis’ was asexually reproduced by cuttings for 3 years now and trialed under different conditions in Europe on Syngenta trial ground properties. It has been found to retain its distinctiveness characteristics through successive propagation, and its novelty appears to be firmly fixed. The new variety reproduces true to type in successive generations of asexual reproduction.

DESCRIPTION OF THE DRAWING

This new Bidens plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full color, the color shown being as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of this new Bidens plant. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, Netherlands. The plant history was taken on 20 weeks old plants, grown in window boxes in Enkhuizen, The Netherlands with day temperatures ranging from 16 and 30 degrees Celsius, and night temperatures ranging from 10 to 16 degrees Celsius.

Color references are primarily to the RHS Color Chart of The Royal Horticultural Society of London.
