Chrysanthemum plant named ‘Jenny Wren Crimson’

Abstract

A new variety of Chrysanthemum plant named ‘Jenny Wren Crimson,’ having a large domed canopy of bright crimson decorative flowers that have very good weather resistance properties.

Description

Latin name of the genus and species: Botanical classification: Chrysanthemum morifolium.

Variety denomination: The new Chrysanthemum variety denomination is ‘Jenny Wren Crimson.’

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of Chrysanthemum botanically known as Chrysanthemum morifolium, and referred to by the cultivar name ‘Jenny Wren Crimson.’

‘Jenny Wren Crimson,’ identified as 30017-2, originated from a naturally occurring whole plant mutation grown in a controlled planting of the variety ‘Jenny Wren’ (U.S. Plant Pat. No. 10,213) in Chichester, West Sussex, United Kingdom. The new variety ‘Jenny Wren Crimson’ has been asexually reproduced by vegetative cuttings in Chichester, West Sussex, United Kingdom and the distinguishing characteristics are retained through successive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

‘Jenny Wren Crimson’ is a garden type of Chrysanthemum plant variety having a domed canopy of bright crimson decorative flowers.

Comparison with Parent

Plants of the new Chrysanthemum variety ‘Jenny Wren Crimson’ are similar to the parent variety ‘Jenny Wren’ in plant habit and growth rate. In side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Jenny Wren Crimson’ differed from plants of the parent ‘Jenny Wren’ in the following characteristic.

• • 1. The new variety ‘Jenny Wren Crimson’ produces crimson flowers whereas the parent ‘Jenny Wren’ produces purple flowers.

Comparison with Other Varieties

Plants of the new Chrysanthemum variety ‘Jenny Wren Crimson’ are dissimilar to the variety ‘Bravo’ (U.S. Plant Pat. No. 6,888) in plant habit and growth rate. In side-by-side comparisons in Chichester, West Sussex, United Kingdom, under commercial practice, plants of the new Chrysanthemum variety ‘Jenny Wren Crimson’ differed from plants of the cultivar ‘Bravo’ in the following characteristics.

• • 1. The new variety ‘Jenny Wren Crimson’ produces more and larger flowers than ‘Bravo.’
  • 2. The new variety ‘Jenny Wren Crimson’ has a more domed and round habit than ‘Bravo.’
  • 3. The new variety ‘Jenny Wren Crimson’ is usually more vigorous than ‘Bravo.’

DETAILED BOTANICAL DESCRIPTION

The following description of the new Chrysanthemum variety ‘Jenny Wren Crimson’ is of plants grown outside, natural season, in Chichester, West Sussex, United Kingdom in the month of June. The cultivar has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in the environment such as temperature, length of day and light intensity, without any variance in genotype. The commercial classification of the new variety is a garden Chrysanthemum.

Plants of the new variety have been grown successfully under temperature conditions averaging about 50° F. at night and about 70° F. to 75° F. during the day under natural light conditions. The plants were grown outdoors in mid-June in 4 liter pots using a loamless compost. No growth retardants were used. To produce a commercial product the plants may be pinched once with the center bud removed. The typical container size for commercial growth is 4 liters (8″). It has been observed that the shelf life of the new variety is about 30 days with a response time of about 9 weeks natural season. The new variety is suitable for growth in a temperature range of 50° F. to 75° F.

The new variety may be produced as a pot plant. The following description is with respect to a plant produced as a garden pot plant. In the description of this new Chrysanthemum variety, color values have been taken from The Royal Horticultural Society Colour Chart (R.H.S.C.C.).
