Rose Hyde Hall

A very tough, reliable, profusely blooming and healthy rose variety. Forms quite a large shrub which is covered all season long with beautiful mid pink, rosette shaped flowers. Due to its prolonged and profuse flowering and vigorous growth it is perfect for planting in groups or as a hedge, when it blooms in masses it creates the most stunning effect. The foliage is healthy, fine and pointed, similar to that of a Wild Rose.

Foliage:

The number of leaflets on normal mid-stem leaves is 5. The foliage is abundant and healthy. Average number of leaves per flowering stem is 8. The leaves are medium to large, having a length of about 12 cm and width of about 9 cm. The colour of the new foliage on the upper side is medium green (Group 143A) and on the lower side is medium brown green (Group 139C).

Prickles:

The quantity of prickles on the main canes from base is many prickles, 23 per 30 cm per stem length. On laterals from main canes there are also a large number of prickles, 16 per 15 cm per stem length. The form of the prickles is hooked downward, length is about 7 mm. The colour of the young prickles is light red pink (Group 36C), and when they mature the colour changes to light brown (Group 165B).

Disease resistance:

In more wet and colder weather tends to get infected with powdery mildew. Pest resistance has not been tested yet.

The cold hardiness is good, recommended for growing in climates similar to USDA 5 and warmer.

Named after the Royal Horticultural Society’s Hyde Hall estate in Essex. Extending to 360 acres, it is home to an excellent collection of roses, including many English Roses. This beautiful garden is situated in an area with low rainfall, which creates challenging conditions for gardening when combined with the exposed nature of the site, so it is good to be able to see so many English Roses thriving there.

ORIGIN OF THE VARIETY

The rose variety ‘Ausbosky’ / ‘Hyde Hall’ originated by David Austin from crossing an unnamed, unpatented seedling which was a result of the following parentage: ‘Ausmas’ / ‘Graham Thomas’ × unnamed seedling) with an unnamed, unpatented seedling.

BACKGROUND OF THE VARIETY

The primary objective of this rose breeding was to produce a very free flowering and healthy variety rose plant, having pink blooms tinted with apricot at the center, and which forms a broad, dense shrub.

SUMMARY OF THE VARIETY

The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics:

 Pink, rosette-shaped blooms, produced with exceptional continuity.

 Broad shrub with dense growth.

 Warm fruity fragrance.

COMPARISON WITH PARENTS

‘Ausbosky’ / ‘Hyde Hall’ has pink blooms and more arching growth which differs from the white blooms of the seed parent.

The blooms of the pollen parent are semi-double compared with the double blooms of ‘Ausbosky’ / ‘Hyde Hall’ and the parent makes a narrower, less dense shrub.

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

‘Ausled’ / ‘A Shropshire Lad’ has paler peach-pink blooms than the pink blooms of ‘Ausbosky’ / ‘Hyde Hall’ and less dense and less vigorous growth.
