Angelonia plant named ‘Cart White’

Abstract

An Angelonia cultivar particularly distinguished by white colored flowers, compact habit and good basal branching.

Description

Genus and species: Angelonia angustifolia.

Variety denomination: ‘Cart White’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Angelonia, botanically known as Angelonia angustifolia, and hereinafter referred to by the cultivar name ‘Cart White’. The new culivar is asexualy reproduced from vegetative cuttings and tissue culture resulting from the cross of the seed/pod parent ‘AngelMist Purple Stripe’, a purple and white bicolor commercial line that is unpatented בAngelMist Lavender’, a lavender commercial line that is unpatented.

‘Cart White’ is a product of a planned breeding program intended to create new Angelonia plants with white colored flowers, compact habit, good basal branching and moderately vigorous growth.

The new cultivar was created in 2000 in Gilroy, Calif. and has been asexually reproduced repeatedly by vegetative cuttings and tissue culture in Gilroy, Calif., Andijk, The Netherlands, and Guatemala over a two and half-year period. The plant has also been trialed at Gilroy, Calif., Litchfield, Mich. and Andijk, The Netherlands. The present invention has been found to retain its distinctive characteristics through successive propagations; and this novelty is firmly fixed.

DESCRIPTION OF PHOTOGRAPH

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

The Photograph shows the mature inflorescence.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Cart White’. The data, which defines these characteristics, were collected from asexual reproductions carried out in Gilroy, Calif. The plant history and photograph was taken on 10 months old plants grown in one-gallon pots in fall/winter season, in a poly-covered greenhouse under 2-4 supplemental light and color readings were taken in the greenhouse in the winter season under natural light. Plants had been cut back numerous times prior to data readings taken. All major branches are cut back about 10-20 cm to keep the plant from becoming unruly. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.). Texture description details were observed under a dissecting microscope according to The New Royal Horticultural Society Dictionary of Gardening (1992).
