Taxus plant named ‘Geers’

Abstract

A new and distinct cultivar of Taxus plant named ‘Geers’, characterized by its outwardly spreading and arching plant form; bright yellow green-colored leaves; foliage resistant to sun and winter burning; and tolerance to low temperatures.

Description

Botanical classification/cultivar designation: Taxus×media cultivar Geers.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Taxus, botanically known as Taxus×media, and hereinafter referred to by the name ‘Geers’.

The new Taxus is a naturally-occurring branch mutation of the Taxus×media cultivar Hicksii, not patented. The Inventor discovered the new Taxus as a single branch mutation within a population of plants of the parent ‘Hicksii’ in a controlled environment in Boskoop, The Netherlands in 1986.

Asexual reproduction of the new Taxus by hardwood cuttings in a controlled environment in Boskoop, The Netherlands since 1996 has shown that the unique features of this new Taxus are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Geers have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and culture such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Geers’. These characteristics in combination distinguish ‘Geers’ as a new and distinct cultivar of Taxus:

• • 1. Outwardly spreading and arching plant form.
  • 2. Bright yellow green-colored leaves.
  • 3. Foliage resistant to sun and winter burning.
  • 4. Tolerant to low temperatures.
  • Plants of the new Taxus are most similar to plants of the parent, the cultivar Hicksii. Plants of the new Taxus differ primarily from plants of the cultivar Hicksii in the following characteristics:
  • 1. Plants of the new Taxus are slower growing than plants of the cultivar Hicksii.
  • 2. Plants of the new Taxus are shorter, but more outwardly spreading and not as upright as plants of the cultivar Hicksii.
  • 3. Plants of the new Taxus are more freely branching than plants of the cultivar Hicksii.
  • 4. Plants of the new Taxus and the cultivar Hicksii differ in foliage coloration as plants of the cultivar Hicksii have dark green-colored foliage.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Taxus.

The photographs on the sheet comprise side perspective views of a typical plant of ‘Geers’ grown in the landscape.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following observations and measurements were grown in Grand Haven, Mich., during the summer in an outdoor nursery and under conditions which approximate commercial Taxus production. During the winter plants were grown in a polyethylene-covered greenhouse. Plants had been growing for about two years when the photographs and description were taken.

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
