Geranium plant named ‘Crystal Lake’

Abstract

A new and distinct cultivar of Geranium plant named ‘Crystal Lake’, characterized by its upright and broadly outwardly spreading plant habit; freely basal branching growth habit; freely flowering habit; light violet blue-colored flowers with purple-colored venation; and good garden performance.

Description

Botanical designation: Geranium wallichianum.

Cultivar denomination: ‘Crystal Lake’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Geranium, botanically known as Geranium wallichianum, and hereinafter referred to by the name ‘Crystal Lake’.

The new Geranium originated from a self-pollination of the Geranium wallichianum cultivar Silver Blue, not patented. The new Geranium was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated self-pollination grown in a controlled environment in Ede, The Netherlands in July, 2002.

Asexual reproduction of the new Geranium by terminal cuttings in a controlled environment in Zandvoort, The Netherlands since January, 2004, has shown that the unique features of this new Geranium are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Crystal Lake has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength 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 ‘Crystal Lake’. These characteristics in combination distinguish ‘Crystal Lake’ as a new and distinct cultivar of Geranium:

• • 1. Upright and broadly outwardly spreading plant habit.
  • 2. Freely basal branching growth habit.
  • 3. Freely flowering habit.
  • 4. Light violet blue-colored flowers with purple-colored venation.
  • 5. Good garden performance.

Plants of the new Geranium differ primarily from plants of the parent, the cultivar Silver Blue in flower color as plants of the cultivar Silver Blue have blue-colored flowers.

Plants of the new Geranium can be compared to plants of the Geranium cultivar Jolly Bee, disclosed in U.S. Plant Pat. No. 12,148. In side-by-side comparisons conducted in The Netherlands, plants of the Geranium differed primarily from plants of the cultivar Jolly Bee in flower color as plants of the cultivar Jolly Bee had darker violet blue-colored flowers.

The accompanying colored photographs illustrate the overall appearance of the new Geranium, 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 Geranium.

The photograph at the top of the first sheet comprises a side perspective view of a typical flowering plant of ‘Crystal Lake’ grown in a container.

The photograph at the bottom of the first sheet is a close-up view of a typical leaf of ‘Crystal Lake’.

The photograph on the second sheet is a close-up view of typical flowers of ‘Crystal Lake’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in Ede, The Netherlands in an outdoor nursery during the summer and autumn. During the production of the plants, day temperatures ranged from 12° C. to 26° C. and night temperatures ranged from 4° C. to 14° C. Plants were about one year old when the photographs and the description were taken. In the detailed description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
