Distinct variety of begonia plant named Danja

Abstract

A new begonia variety is characterized by its strong growth, abundant flowering, and soft pastel yellow flower color.

Description

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct cultivar of Begonia.times.hiemalis known by the varietal name of Danja. The new cultivar resulted from the self pollination of the cultivar Rosalie (U.S. Plant Pat. No. 6,321). The new cultivar has the same habit and growing characteristics as Rosalie but has a different leaf shape and flower color. The new variety has a leaf shape with an acute tip with an irregularity lobed attachment whereas Rosalie has a shape of an ovate tip with an oblique petal attachment. The new variety has a flower color which is soft pastel yellow as compared to the pastel peach with pink tones of the flower of the variety Rosalie.

The new cultivar was discovered in April of 1985 at Limaplant, b.v. in Lisse, Holland, was first asexually reproduced by cuttings at Limaplant, b.v. in Lisse, Holland and has been asexually reproduced by cuttings for Oglevee Limited in Connellsville, Pa. It has been found to retain its distinctive characteristics through successive propagations.

The new cultivar is generally characterized by its strong growth and abundant flowering. The plant has short compact internodes with good basal branching. The strong stems give good self support. The soft pastel yellow coloring fulfills a market need.

The new cultivar, when grown in a greenhouse in Connellsville, Pa., has a response time of 9 to 10 weeks from a well-rooted cutting to a flowering finished plant in a six inch pot (no pinch).

DESCRIPTION OF THE DRAWING

The accompanying drawing illustrates the new cultivar, the color being as nearly true as possible with color illustrations of this type.

DESCRIPTION OF THE NEW PLANT

The following detailed description sets forth the characteristics of the new cultivar. The data which define these characteristics were collected from asexual reproductions carried out for Oglevee Limited in Connellsville, Pa. The plant history was taken on ten week plants blossomed under natural light in a greenhouse and grown under temperature conditions of 62.degree. F. at night and 68.degree. F. during the day. The plants were potted in July of 1987 in a peat-lite mix and fertilized with a mixture of 20N-10P-20K. Color readings were taken indoors under 200 footcandles of cool white fluorescent tubes. Color references are to the R.H.S. Colour Chart of The Royal Horticultural Society of London, unless noted differently.

Persistence.--Very good flower response, produces high number of buds.

Reproductive organs: None observed with reproductive organs formed into petaloids.

Plant:

Form.--Short and compact; internodes; good basal branching; strong stems; good self-support.

Growth.--Very vigorous; upright growth habit.

Height from soil line.--25 to 28 cm. in 10 weeks (no pinch, no cycocel).

Spread.--25 to 30 cm. in 10 weeks (no pinch, no cycocel).

Foliage:
