Snapdragon plant named ‘Drarose’

Abstract

A snapdragon cultivar particularly distinguished by pink flowers, vigorous growth and basal branching.

Description

GENUS AND SPECIES

Antirrhinum hybrida.

VARIETY DENOMINATION

‘Drarose’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of snapdragon, botanically known as Antirrhinum hybrida, and hereinafter referred to by the cultivar name ‘Drarose’. The new cultivar is asexually reproduced from vegetative cuttings and tissue culture resulting from the cross of the seed/pod parent CF1-26, an unnamed and unpatented pink proprietary line and the pollen parent CF1-10, an unnamed and unpatented bronze proprietary line.

‘Drarose’ is a product of a planned breeding program intended to create new snapdragon cultivars with rose colored flowers, dark green foliage, vigorous growth and basal branching.

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. over a one year period. It has also been trialed at Gilroy, Calif.; Litchfield, Mich. and Andijk, The Netherlands. It has been found to retain its distinctive characteristics through successive propagations; and this novelty is firmly fixed.

DESCRIPTION OF PHOTOGRAPH

This new snapdragon 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.

FIG. 1 shows the mature inflorescence.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed descriptions set forth the distinctive characteristics of ‘Drarose’. The data which defines these characteristics were collected from asexual reproductions by tissue culture or vegetative cuttings carried out in Gilroy, Calif. The plant history was taken on 19-21 week old plants grown in 8 inch pots, blossomed under natural light in a greenhouse and color readings were taken in the greenhouse in Gilroy, Calif. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.).

COMPARISON WITH KNOWN CULTIVARS

When the instant plant is compared to Luminaire Pink (not patented) the ‘Drarose’ foliage is longer and narrower while Luminaire Pink is more elliptic/lanceolate. Additionally flowers of ‘Drarose’ is a deeper rose color than flowers of Luminaire Pink.

Drarose differs from the female parent (CF1-39) (not patented) in numerous ways such as: 1) Drarose is a different color; Drarose has a rose colored flower while CF1-26 is a pink flower. 2) Drarose has a more prostrate habit than CF1-26. 3) Drarose is a more vigorous plant than CF1-26.

Drarose differs from the pollen parent CF1-10 (not patented) in numerous ways such as: 1) Drarose has a rose colored flower while CF1-10 has a bronze flower. 2) Drarose has a darker green leaf than CF1-10. 3) Drarose has a larger flower size than CF1-10.
