Abstract
Poinsettia `586` is a new cultivar of the "curly" flower type, distinguished by red flower bracts, unique flower bract formation and presentation, dark green foliage and self-branching characteristics. The new plant produces a very desirable branched flowering pot plant. The post-production foliage and bract retention is excellent even under low light intensities in the consumer's home.
Description
This new Poinsettia cultivar, `586,` originated as an induced self-branching sport of a seedling known as `H-45` (proprietary) in my greenhouse in Encinitas, Calif. It was selected because of its unusual flower bract formation and bract presentation, red flower bracts, dark green foliage and self branching characteristics; traits which distinguish it from other poinsettia cultivars, and seem to make it a desirable plant for commercial greenhouse production. After selection, `586` was vegetatively reproduced from stem cuttings for test purposes in Encinitas, Calif. By subjecting clones of this plant to successive generations of vegetative propagation, it was demonstrated that the distinctive characteristics of `586` held true from generation to generation.
Poinsettia `586` is illustrated in the accompanying color photographs.
The upper photo is a side view of 3 single stem plants per pot in full flower. Evidence of self-branching can be seen in the flowering axillary branches beneath the upper canopy of bracts.
The lower photo is a top view of the same plants showing flower and bract formation.
The following is a detailed description of this new poinsettia as observed in Encinitas, Calif., U.S.A. during December 1992. Observations were recorded from flowering plants, grown as 3 single stem plants per pot. The pot was 14 cm in diameter and 11 cm in height. Color designations are compared to the 1986 edition of R.H.S. Colour Chart, first published in 1966 by The Royal Horticultural Society, London, England.
This new plant of the "curly" flower type is distinctly different than the poinsettia named `Red Curly` (U.S. Plant Pat. No. 4,952) in the following respects. Poinsettia `586` is self branching; `Red Curly` has little tendency to branch. The stem stiffness of this invention is significantly improved over `Red Curly.`
Origin: Sport of a non-patented and undistributed seedling known as `H-45.` The sport was induced by application of the procedures set forth in U.S. Pat. No. 4,724,276 to the seedling plant, herein incorporated by reference. The rootstock used to create `568` was Dark Red Hegg (U.S. Plant Pat. No. 3,160).
Classification:
Botanic.--Euphorbia pulcherrima Willd.
Common name.--Poinsettia.
Cultivar name.--`586`.
Form: Shrub.
Height: Medium.
Growth habit: As a single stemmed plant, upright and vigorous with self-branching side shoots. The application of a chemical growth retardant may not be needed to restrict height for commercial pot plant production. I observed 3 unpinched plants in a pot with an overall height of 51 cm and an overall width of 35 cm. The bract diameter of individual flowers was 20 cm.
Branching: Axillary branches will develop and terminate in a flower without pinching. However, it is usually desirable to pinch `586` before flower induction and remove all terminal dominance. Then, all axillary branches will develop uniformly and at a faster rate.
Growth rate: Rooting of stem cuttings occurs in 12-18 days under intermittent mist. The plant will flower in about nine weeks under continuous long night conditions and night temperatures of about 16°-18° C.
Foliage: The foliage is clean and uniformly dark green from bottom to top of the plant. The leaves are of medium size, leaf blades typically being 8-9 cm long and 9-10 cm wide with leaf petioles 3 cm long.
Leaf shape.--Typical leaves are generally ovate with obtuse bases and acuminate tips. Leaf margins are lobed, generally with 2 indentations on each side of the leaf blade. The midrib is convoluted or curled. The unique appearance of the leaves may be described as puckered and arched as might be caused by pulling a drawstring inside the midrib.
Color.--Upper side -- Dark green, near RHS 147A-B. Under side --Green, between RHS 147B-C.
Retention.--The foliage lasts extremely well even under low light intensities in the consumer's home.
Bracts: Generally there are 18-21 red bracts of various sizes subtending the cyanthia. The primary bracts have blades typically 11-12 cm long and 9-10 cm wide with petioles 2 cm long. The bract surface is rugose with the midrib convoluted or curled. Together, the convexity of the bracts make a coarsely convoluted, spherical flower head.
Shape.--Primary bracts are ovate with acute to obtuse bases and acuminate tips. Primary bract margins are lobed, generally with 2 indentations on either side of the bract. Secondary bracts are elliptic, of various sizes and have entire margins.
Color.--Upper side -- Red, near RHS 45B. Under side -- Near RHS 45D.
Flowers: Generally, 19-22 cyathia (flowers) are present when the plant is in full bloom. Each cyathium is about 7 mm long and 6 mm wide, green in color, and fringed with red at the distal end. One yellow nectar cup protrudes from the side of each cyathium and secretes nectar. The flower pedicel is also green and about 5 mm in length. The stamens protruding from the cyathia are red. The anthers are bifurcate; the pollen is yellow and copious. The stigmas are red and trifurcate.
Nectar exudate.--Abundant.
Seeds.--Self-incompatible.
Fertility.--Not observed.
Post production: The leaf, cyathium and bract retention is excellent and the bracts do not fade or discolor.
