Rose Jayne Austin

The medium-sized flowers begin as shapely, shallow cups and gradually open into classic rosettes, often with a charming button eye at the center. The color is a glowing, buttery yellow infused with apricot in the center, fading to paler, almost creamy outer petals, while the petal backs retain deeper tones, creating a soft, diffused effect. In cooler temperatures, the color remains rich and warm, while in heat, the flowers may fade more quickly.

DESCRIPTION OF THE VARIETY

Throughout this description of the rose variety 'Jayne Austin' is provided with color descriptions using terminology of the "Methuen Handbook of Colour" published by Eyre Methuen Ltd. (1963), except where common terms of color definition are employed. Phenotypic expression may vary with environmental, cultural and climatic conditions, as well as differences in conditions of light and soil.

FLOWERING

This rose variety has a recurrent flowering habit. Blooms in flushes with short breaks from summer until frosts. The number of blooms per plant during the growing season is profuse, but there are too many to count.

Flower bud:

The flower buds of 'Jayne Austin' rose variety are medium sized, about 2.5 cm (1") cm long when the petals start to unfurl. The bud form is medium, globular with long cuspidate apex. When the sepals first divide, the bud color is brownish red (Group 8C6). When half open, the upper and the lower sides of the petals are pale yellow (Group 3A3) to light yellow (Group 3A5) at the base. Calyx is star-shaped when fully opened with the sepals folding back.

The shape of the sepals is lanceolate, the surface texture is leathery, slightly grainy. The colour on the upper surface is greyish green / bracken green (Group 29D to 29E7). There are 3 normally appendaged sepals and there are 2 unappendaged sepals with hairy edges.

The receptacle is garnet brown / reddish brown (Group 9D8), goblet shaped and has a smooth surface. The size of the receptacle is medium, small, about 0.95 cm (3/8") cm long and about 0.64 cm (1/4") cm in diameter.

The peduncle is medium, averaging to about 4.5 - 7.0 cm (1 ¾ - 2 3/4") cm in length, erect strength and has a glandular surface. The colour of the peduncle varies from light green to bronzy to greyish green / lattuce green (Group 30D7) with brownish violet blush (Group 11D7).

Bloom:

The flowers are medium-sized, the average diameter of the open flower is about 6.4 - 8.3 cm (2 1/2-3 1/4") cm. When first open, the flower form is cupped, and the form slattens as the flower fully open revealing a quartered rosette in the center, outer petal edges curl slightly. Flowers are very full, the number of petals under normal conditions varies from 70 to 100. They are born singly or several together in clusters having irregular shape, of up to 6 flowers together. The flowering stem has normal strength, long, and has an average length of about 61–76 cm (24 to 30 inches).

When first open the colour of the upper sides and the reverse sides of the petals varies from light yellow (Group 2A5) to pale yellow (Group 4A3). The base of the petals is yellow (Group 3A6). The major color on the upper side of the flowers is pale yellow (Group 4A3). Under normal growing conditions no variegation is observed on the flowers of rose variety 'Jayne Austin'.

The general tonality at the end of the first day is pale yellow (Group 4A3) but very faded. At the end of the third day the general tonality fades further and varies from reddish white / pinkish white (Group 7A2) to pale yellow (Group 3A3).

Petals:

The texture of the petals is sheeny, thick and the surface is smooth; the shape of the petals is round, heart-shaped, and the petals form is cupped. The arrangement of the petals is quartered, the inner petals caught into calyx to form a button, with few petaloids in the center.

Normally there are few petaloids present in the center of the flowers.

The petals of this rose variety have moderately good self-cleaning quality, they usually hang on and dry on the plant. Under normal climate conditions the petals last fairly long, on the plant they last for about 7 days, as a cut flower their lastingness is about 4 to 7 days.

Fragrance:

The fragrance of the rose 'Jayne Austin' is strong and distinctive, with rich myrrh and Tea Rose scent with subtle lilac or spicy undertones, delicate yet persistent, making it ideal for both garden enjoyment and cutting. It was considered by Austin one of the more perfumed roses of his yellow and apricot group.

Reproductive parts:

The number of stamens is 5-35 on average per flower, they are medium sized and tucked in calyx or partly so.

The anthers are medium sized and have yellow colour.

The colour of the filaments is yellow as well.

The pollen is golden yellow.

The colour of the styles is pale green (Group 30A3).

Stigma are yellow, with ruby / cerise colour (Group 12C8) at the base.

The hips of this rose variety have not been observed.

PLANT

The rose variety 'Jayne Austin' is classified as a Shrub rose and is part of David Austin’s English Shrub Roses collection. The growth character is moderately vigorous, branching. Grows upright and slender, reaching about 100 - 140 cm (3.2 - 4.5 ft) in height and 80 - 90 cm (2.5 – 3 ft) wide, though in warm climates it can become taller and rangier. While the narrow, erect stems lend elegance, they can become ungainly if left unchecked. Strategic pruning, especially of long, maturing canes, will help maintain a balanced, rounded shape. The plant tends to send up vigorous basal shoots and will benefit from planting in groups of three to support a fuller look.

'Jayne Austin' is a refined and elegant English shrub rose that stands out for the luminous quality of its soft apricot-yellow blooms and the silken texture of its petals - a legacy of its Noisette ancestry, particularly the famed Gloire de Dijon. With its luminous color, classic form, and exceptional fragrance, 'Jayne Austin' is a beautiful choice for mixed borders, cottage-style gardens, or back-of-border plantings. Though it requires a bit more care than some modern roses, its charm and sophistication make it a rewarding rose for dedicated gardeners and fragrance lovers alike.

Foliage:

There is a normal quantity of the foliage on the plants of this rose variety. The number of leaflets on normal mid-stem leaves varies from is normally 5, including the terminal leaflet. The foliage is medium sized.

The colour of the juvenile foliage is deep green (Group 29E8) while the mature foliage is dark green (Group 28F7).

Leaflets:

The size of the leaflets is medium, they are about 4.5 cm (13/4") cm long. The shape of the leaflets is ovate, the shape of the leaflet tip is pointed and the base shape is round. The surface texture of the leaflets is leathery, semi-glossy. The edges are serrated, the type of serration is single and small.

The petiole has deep green / parrot green colour (Group 30E8) with brownish violet blush (Group 11D7), and has prickles on the underside, about 1 to 3 per internode. The petiole rachis is also deep green / parrot green (Group 30E8) with brownish violet blush (Group 11D7).

The stipules are 1.9 cm (3/4") cm long, serrated, have a glandular surface.

Wood:

The new wood of this rose variety has deep green / parrot green colour (Group 30E8) and smooth bark. The mature wood is deep green (Group 29E8), the bark remains smooth.

Stems:

The mature stem has an average length of about 61–76 cm (24 to 30 inches) cm. The stem pubescence is not observed on the stems of this rose variety. The above measurements are all variable, depending on growing conditions in a season.

Prickles:

There are ordinary numbers of prickles present on the main canes from base. On the laterals from main canes there is an ordinary to few quantity of prickles. The shape of the prickles is straight, they are medium-sized and evenly spaced along the stem. The colour of the prickles is rosewood / redish brown (Group 9D5).

Small prickles:

Under normal growing conditions the small prickles are not observed on the main canes and on the laterals from the main canes of rose variety 'Jayne Austin'.

Disease resistance:

The rose variety 'Jayne Austin' has relatively good resistance to most common rose diseases, in particular it is resistant to mildew, blackspot and rust under normal growing conditions. It is moderately susceptible to mildew and rust in cooler or humid climates. It performs best in mild, temperate zones and should be given good air circulation and protection from intense sun, which can cause petal scorch. The pest resistance has not been tested yet.

Rose variety is recommended for growing in climate conditions similar to USDA 5 and requires winter protection in more colder climates.

This rose was named in honor of David Austin’s daughter-in-law, Jayne Austin.

ORIGIN OF THE VARIETY

Rose variety ‘Ausbreak’ / 'Jayne Austin' originated by David Austin by crossing female parent (seed parent) - English shrub rose 'Ausmas' / 'Graham Thomas' with the male parent (pollen parent) - English shrub rose 'Austamora' / 'Tamora'.

BACKGROUND OF THE VARIETY

The primary objective of this rose variety breeding was to create a new rose variety with yellow, quartered, scented flowers on a bushy plant which repeatedly flowers.

SUMMARY OF THE VARIETY

The objective was achieved, along with other important improvements, and this rose variety incorporated the following unique combination of characteristics:

 paler colored flowers than parents;

 taller and more sturdy than 'Austamora' / 'Tamora';

 flowers flatter and more quartered than parents;

 highly scented.

Asexual reproduction of this variety by budding showed that the foregoing and all other characteristics and distinctions came true to form, established and transmitted through the succeeding propagations.
