USPP29068P3 - Crassula plant named ‘Indian Summer’ - Google Patents

Abstract

A new cultivar of Crassula plant named ‘Indian Summer’ that is characterized by obovate shaped leaves that are yellow-green on the upper side when young and that turn grey-red toward the margins during autumn on outdoor grown plants.

Description

Botanical classification: Crassula ovata.

Variety denomination: ‘Indian Summer’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Crassula plant botanically known as Crassula ovata and hereinafter referred to by the cultivar name ‘Indian Summer’.

‘Indian Summer’ was discovered as a naturally occurring branch mutation of Crassula ovata ‘Sunset’ (not patented). ‘Indian Summer’ was discovered in 2008 on a plant of Crassula ‘Sunset’ grown in a greenhouse in a cultivated area of Honselersdijk, Netherlands.

Asexual reproduction of the new cultivar ‘Indian Summer’ first occurred by leaf cuttings in 2010 in Honselersdijk, Netherlands. Since that time, under careful observation, the unique characteristics of the new cultivar have been uniform, stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Crassula cultivar ‘Indian Summer’. These traits in combination distinguish ‘Indian Summer’ as a new and distinct cultivar apart from other existing varieties of Crassula known by the inventor.

• 1. Crassula ‘Indian Summer’ exhibits obovate shaped leaves.
• 2. Crassula ‘Indian Summer’ exhibits young leaves that are yellow-green on the upper side.
• 3. Crassula ‘Indian Summer’ exhibits leaves that turn grey-red toward the margins during autumn on outdoor grown plants. The leaves of indoor grown plants do not turn grey-red toward the margins.

The closest comparison cultivars are the parent plant Crassula ‘Sunset’ and Crassula ‘Minor’ (not patented). ‘Indian Summer’ is distinguishable from the parent plant Crassula ‘Sunset’ by the following characteristics:

• 1. Crassula ‘Indian Summer’ exhibits leaves that are smaller than the leaves of Crassula ‘Sunset’.
• 2. Crassula ‘Indian Summer’ exhibits young leaves that are yellow-green on the upper side. The young leaves of Crassula ‘Sunset’ are green on the upper side.
• 3. Crassula ‘Indian Summer’ exhibits leaves that turn grey-red toward the margins during autumn on outdoor grown plants. The leaves of Crassula ‘Sunset’ have margins that are lighter grey-red during autumn.
  ‘Indian Summer’ is distinguishable from Crassula ‘Minor’ by the following characteristics:
• 1. Crassula ‘Indian Summer’ exhibits leaves that are larger than the leaves of Crassula ‘Minor’.
• 2. Crassula ‘Indian Summer’ exhibits young leaves that are yellow-green on the upper side. The young leaves of Crassula ‘Minor’ are bronze in color on the upper side.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits of Crassula ‘Indian Summer’. The photograph shows an overall view of a 14 month old plant.

The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Crassula cultivar named ‘Indian Summer’. Data was collected in Honselersdijk, Netherlands from 14 month old plants grown in a glass greenhouse in 10.5 cm. diameter containers. The time of year was October and the temperature range was 20-25 degrees Centigrade during the day and 10-15 degrees Centigrade at night. The light level was natural light level. No photoperiodic treatments or growth retardants were used. Color determinations are in accordance with The Royal Horticultural Society Colour Chart 2007 edition, except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species. ‘Indian Summer’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.
