Trees and Shrubs
A division of the Camden Park catalogues that is not clearly defined. In broad terms it includes all plants with woody stems except conifers and fruit trees and shrubs.
Rhododendron ponticum L. var. album
See Rhododendron ponticum L. for details of the species. White flowered forms occasionally occur naturally. [RHSD].
Rhododendron ponticum L. var. roseum
See Rhododendron ponticum L. for details of the species. Presumably a variety with pink flowers although I have found no specific reference to roseum. Hilliers' describes the colour of the flowers of R. ponticum as varying from mauve to lilac-pink.
Rhododendron pulchrum Sweet
A small to medium bush with rose-purple flowers with dark spots, 5-6cm across, borne in clusters of 1 to 4, introduced into England in 1824 and not known in the wild. [Hortus, Hilliers'].
Rhododendron viscosum ‘Violae-odora’
Treated here as a cultivar of Rhododendron viscosum Torr. but may be naturally occurring. See Rhododendron viscosum Torr. for more detail. A deciduous azalea with hairy shoots, elliptic leaves, to 3cm long, often glaucous beneath, and trusses of up to 12 tubular or funnel-shaped fragrant white flowers suffused with pink, to 3cm long, appearing after the leaves in summer. To 2.5m. [RHSE, Hilliers']. Violae-odora is presumably a form considered to have the scent of violets.
Rhododendron viscosum Torr.
Deciduous azalea with hairy shoots, elliptic leaves, to 3cm long, often glaucous beneath, and trusses of up to 12 tubular or funnel-shaped fragrant white flowers suffused with pink, to 3cm long, appearing after the leaves in summer. To 2.5m. [RHSE, Hortus, Hilliers'].
Rhododendron x alterclerense ‘Aurorae’
Probably a cultivar of Rhododendron x alterclerense Lindl. Listed in the 1836 edition of Loddiges’ Nursery catalogue as Azalea hybridae altaclerensae aurorae under Hardy Trees & Shrubs. I have found no specific description of this azalea.
Rhododendron x alterclerense ‘Coccinea Nobilis’
This plant is almost certainly one of the early Highclere hybrids known collectively as Rhododendron x alterclerense Lindl. Azalea hybridae altaclerensae coccinea nobilis is listed in the 1836 Loddiges’ Nursery catalogue, a copy of which is held at Camden Park [CPA]. It is not listed in the 1830 edition. I have found no specific description of this azalea.
Rhododendron x alterclerense ‘Govenianum’
A cultivar of Rhododendron x alterclerense Lindl. ‘This hybrid was raised in the collection of the Earl of Caernarvon at Highclere by J. R. Gowen from seed of “A. nudiflora or A. viscosa … fertilised with the pollen of a hybrid Rhododendron between R. ponticum and R. cataubiense.” The leaves are evergreen or scarcely deciduous, elliptic-oblong or lanceolate-oblong, pubescent on both sides when young, glabrous above and glossy when old. The flowers are light purple, rather small, with a comparatively long and narrow tube. From the illustration it is impossible to judge whether R. nudiflorum or R. viscosum is one of the parents.’ [Wilson and Rehder p.189].
Rhododendron x alterclerense ‘Regalis’
Presumably a cultivar of Rhododendron x alterclerense Lindl., but I have found no specific description of this azalea.
Rhododendron x alterclerense ‘Thyrsiflora’
Probably a cultivar of Rhododendron x alterclerense Lindl. Listed in the 1836 edition of Loddiges’ Nursery catalogue as Azalea hybridae altaclerensae thyrsiflora under Hardy Trees & Shrubs. I have found no description of this azalea.
Rhododendron x alterclerense Lindl.
An English hybrid azalea with crimson flowers. [PD]. This is undoubtedly one of the old Highclere hybrids of which 25 are listed in the 1836 edition of Loddiges’ Nursery catalogue, a copy of which is held at Camden Park. Macarthur’s plant is likely to have been one of these. See other references to varieties of Rhododendron x alterclerense for further details.
Rhododendron x azaleoides Desf.
Probably a Rhododendron ponticum L. x Rhododendron nudiflorum Torr. hybrid. Hardy evergreen shrub of dense habit, the leaves glaucous beneath, to 8cm long and flowers in clusters of up to 20, whitish, tinged with pale purple. To 2.4m. [RHSD, Hortus, Hilliers’].
Rhododendron x gandavense ‘Amoenissima’
A cultivar of Rhododendron x gandavense Rehder, ‘Amoenissima’, an old Ghent hybrid, probably very similar to Rhododendron obtusum Planch. var. amoenum Wils., a plant long cultivated in Japan, with magenta flowers, usually double. The Kurume hybrids are derived from this plant. [RHSD, Hortus, Hilliers', Millais]. Azalea amoenissima may be a ‘more beautiful’ (amoenissimum) azalea, similar to the ‘beautiful’ amoenum but this is by no means certain.
