Abstract
A new cultivar of Forsythia intermedia named 'Tinkle Bells' characterized by its floriferousness, its semi-dwarf, upright character, its downwardly directed flowers, and its leaves which are serrated only at their upper ends.
Description
This invention relates to a new cultivar of Forsythia intermedia named "Tinkle Bells", which is characterized especially by its semi-dwarf character, its upright growth habit, its pendulous flower buds and flowers, and the acute leaf tips on flowering wood foliage.
The new variety is a vegetative selection derived from a vegetative line of mutants, which had been produced in turn by subjected rooted cuttings of the parent Forsythia intermedia "Lynwood Gold" (F. intermedia "Spectabilis") to irradiation with 1,200 rad fast neutrons.
In 1968, three hundred cuttings of "Lynwood Gold" that had been potted and held in cold storage (38° F.) for six weeks and then returned to the greenhouse for two days were irradiated with 1200 rad fast neutrons. One of the plants of this group that broke dormancy formed a shoot with variegated foliage. This plant was cut back repeatedly to induce branching and eventually formed shoots that exhibited different characteristics. Each shoot was propagated by stem cuttings over 10 vegetative generations of selection and propagation. From this plant population two vegetatively selected types and three seedlings were selected. Further propagation and testing of these selections over several more years were shown to be the stable and new forsythia varieties that are the subject of this and four other co-pending plant patent applications; viz:
______________________________________ Ser. No. Name Type ______________________________________ 272,063 "Lemon-Screen" vegetative selection 273,489 "Tinkle Bells" vegetative selection 271,919 "Minikin" seedling 271,665 "Fairy Land" seedling 271,666 "Pygmy-Red" seedling ______________________________________
Each differs greatly from the parent "Lynwood Gold" and also from one another.
"Tinkle Bells" was selected from a group of vegetatively propagated shoots because it was very floriferous and attractive when in bloom. Cuttings from this plant have been rooted in soil and asexually propagated, and its progeny have displayed homogenous and stable characteristics.
Throughout this specification, color names beginning with a small letter signify that the name of the color as used in common speech are aptly descriptive. Color names beginning with a capital letter designate values based on the R.H.S. Colour Chart, published by The Royal Horticultural Society of London, England.
The accompanying drawings illustrate the new variety in color as grown in Knox County within the State of Tennessee.
FIG. 1 illustrates a five year old "Tinkle Bells" plant in spring bloom.
FIG. 2 shows flowered cut stems.
FIG. 3 is a close-up view of the flowers of FIG. 2.
FIG. 4 illustrates the "Tinkle Bells" plant in summer foliage.
FIG. 5 is a closer view of the foliage shown in FIG. 4.
The following characteristics distinguish "Tinkle Bells" from its parent and other Forsythia cultivars:
Although "Tinkle Bells", like its parent "Lynwood Gold", exhibits an upright growth habit, the ultimate height of "Tinkle Bells" is 4 to 41/2 ft. The plant exhibits medium vigor and is hardy in Zone 6b or lower. Because of its upright habit, "Tinkle Bells" tends not to self propagate by natural layerage, but the plant expands by stooling, i.e., shoots arise from the ground around the base of the plant, and the stooling can be controlled with post-emergence herbicides. Its upright growth habit and flowering at an early age make "Tinkle Bells" suitable for container growth and forcing. "Tinkle Bells" has a number of landscape applications, particularly for border and low screen plantings. The plant requires minimal pruning and has disease and insect-resistant foliage.
Its parent, "Lynwood Gold", by contrast is tall and slender--a straight upright variety with erect stems and which attains a height of 6 ft. to 71/2 ft. at maturity.
The stems of "Tinkle Bells" are yellow green when young and light brown when mature. The stems are rigid and the pith is sparsely lamellate between nodes.
The stems of the "Lynwood Gold" parent are green when young and brown when mature; they are a bit stiff; the pith at the nodes is lamellate, and on one year shoots, the stems between nodes are hollow.
"Tinkle Bells" flower early with bright yellow flowers (Yellow 7B) which generally have four, but occasionally five or six petals; the corolla is 1/2 inch long, opening up to approximately a 45 degree angle with a total spread of 1/2 in. to 3/4 in. The pollen sacs of the stamen are located slightly below the stigmas of the short pistils. The plant generally produces two, but often four flowers per node on the flowering wood, which has internodes 1/2 to 11/2 in. long. Both the buds and resultant flowers are pendulous on upright stems.
The "Lynwood Gold" parent is fertile and has pistils that extend well above its pollen sacs, is late flowering and its medium sized flowers (about 1" to 11/2" in diameter) are almost evenly spaced on the stem. The flowers of "Lynwood Gold" are brilliant yellow (lighter than its parent, F. spectabilis). The corolla lobes of "Lynwood Gold" are reflexed and its petals are large, broad open and elliptic.
The "Tinkle Bells" leaves are medium green both in the young and mature stage. The leaves are simple elliptical, generally serrate, but only on the upper one-third, near the tip. The leaves are acute on flowering shoots and acuminate on vegetative shoots. The leaves are 1/2 in. wide and, including the petiole, are 2 in. to 3 in. long.
The leaves of the "Lynwood Gold" parent, on the other hand, are ovate lanceolate in shape and about 3" to 41/2" long and about 1" to 11/2" wide. Both young and old leaves are deep green in color.
To facilitate the comparison of the characteristics and features of "Tinkle Bells", the subject of this application, and its parent, "Lynwood Gold" and also with the four other new mutant offspring varieties of "Lynwood Gold" referred to above, there are attached hereto as Tables 1-5 comparative tabulations of the characteristics and properties of parent and its five offspring mutants that were developed from a single irradiated plant of "Lynwood Gold." Table 1 compares "Tinkle Bells" and its parent "Lynwood Gold". Table 2 compares "Tinkle Bells" and "Pygmy-Red". Table 3 compares "Tinkle Bells" and "Lemon-Screen". Table 4 compares "Tinkle Bells" and "Minikin". Table 5 compares "Tinkle Bells" and "Fairy Land".
