A very unusual and highly endangered species from Taiwan; probably the finest species in flower. Very fast growing, drought tolerant, small deciduous tree best in full sun. Long panicles of large, lilac-blue foxglove-like flowers, heavily spotted inside, are borne on the bare branches in May. Typically huge leaves have an interesting sticky hairiness.
Paulownia tomentosa W769
Brought back from the brink by Pan Global', this is the extra vigorous, large growing form Wilson originally introduced from W. Hupeh, China, which reached a whopping 26m at Westonbirt before its death in 1990, far bigger than is normally associated with this species. It also grew at Colesbourne, where this material was derived. Typical big leaves and lilac foxglove flowers.
Philadelphus 'Casa Azul'
This was found as a seedling in my garden, growing between two Mexican parents. The ultimate size is not yet known but so far it appears to be a shrub to perhaps 2m. Particularly sweetly scented, cup shaped white flowers with a subtle central purple-red stain are borne in profusion in early summer over narrow, dainty foliage on exceptionally arching stems.
A sister of famous names such as 'Belle Etoile', 'Bicolore', 'Sybille' etc. and like them with purple blotched heavily scented flowers. A small to medium sized deciduous hardy shrub with arching stems hung with masses of white, highly fragrant flowers, each very heavily blotched with purple at the base of each petal. Easy in most locations, flowering more intensely with more sun.
Another of the virtually unheard of Mexican species, yet one of the most attractive. This one makes an arching shrub, so far to about 1.8m in my garden, with big, flat, scented white flowers in summer. A particular feature is the whitish-grey hairy underside to the leaves. Most rare and frankly rather desirable.
Philadelphus delavayi BO-13-083 (new)
A large vigorous, deciduous shrub bearing dense racemes of heavily scented, large white flowers in June. One of the finest species. This is the real thing, collected in SW China. Easy in virtually any soil or situation, sun or semi-shade.
Philadelphus delavayi f. melanocalyx B&L 12168
Much sought after, this form of this already superb species has dark-purple calyxes behind the pure white petals. The flowers are sweetly and heavily scented and are produced in dense racemes in June. Makes a large deciduous shrub for sun or semi-shade. This is a particularly fine clone with graphite tones in the new growth. Easy and hardy.
Philadelphus karwinskianus F&M 152
A large species from Mexico, collected in N. Puebla State, this is closely related to P. mexicanus but is even more vigorous and scandent in growth, clambering over other things to make a large semi-evergreen almost climbing shrub with elegant foliage and terminal panicles of large heavily perfumed white flowers. This needs a warm position like P. mexicanus.
Philadelphus maculatus 'Mexican Jewel'
A fine selection of this hardy deciduous 2m tall shrub from the high mountains of Mexico. Intensely sweet, unarguably bubble-gum scented white flowers with red-purple centres borne in June. This superior clone was collected and named by Martyn Rix, that fine botanist and altogether nice chap from Devon. The scent from this eclipses any other species.
Philadelphus madrensis F&M 326
Most (all?) stock of this species in UK cultivation is in fact P. maculatus. Here we have the real thing, that we found in Durango State, Mexico, which differs in its pure white flowers and lightly toothed foliage. Masses of extremely sweetly scented white flowers in early summer on a shrub to only 1m in the wild, though in cultivation will probably reach 1.5 to 2m.
From the Sierra Madre Oriental mountains in NE Mexico and neighbouring Texas and Arizona, this very rare little evergreen 'Mock Orange' makes a small shrub with arching branches up to about 1m high, with sweetly scented white flowers in June. For sun or semi-shade in most soils.
A most desirable species of 'Mock Orange', rarely seen, forming a shrub to about 2m with arching branches covered in clusters of sweetly scented white flowers with contrasting purple calyces in June. This is similar to P. delavayi var. melanocalyx but the calyces are slightly more of a red-purple than any of the clones I have of the former. Easy and hardy.
Philadelphus schrenkii var. jackii (new)
A rare species, from NE China and Korea in this variety, making an upright large shrub with very fragrant white flowers in June/July. Akin to the European P. coronarius. Any ordinary soil, even thin chalk.
A medium sized, compact evergreen shrub for a sunny site and drought tolerant with it. Slender dark green foliage and large amounts of small fragrant, cream flowers in clusters along the branches in May and June. Ideal for seaside gardens but hardy and easy inland. Related to the olive but hardier and giving a similar mediterranean feel.
Phillyrea angustifolia 'French Fries'
Originally released here, this is my own selected form from a collection made in southern France with exceptionally narrow, very pretty foliage. A medium sized evergreen shrub with large amounts of small, fragrant, cream flowers in clusters along the branches in May and June. Very drought tolerant. It is, I believe, the true forma rosmarinifolia.
A very characterful small evergreen tree for Mediterranean effect. A rounded, dense, bushy tree or large shrub, enhanced by the small, black-green, leathery foliage contrasting with pale beige bark. Small white flowers in spring are borne profusely. Much used in period plantings. Hardy and drought tolerant. It's difficult to describe quite how good this is.
This came to me as P. angustifolia, which is a synonym of P. fruticosa. Its true identity is unclear; it needs a name, so I've given it one for the wonderful foliage texture it possesses, having soft grey-green leaves longitudinally in-rolled to show very pale grey undersides. Yellow flowers in early summer. A small evergreen shrub for sun and drainage.
Phlomis bourgaei NJM 12.015
Collected in SW Turkey near Sinneli at 1100m alt, this unusual species has broad green foliage in winter. In the Med' summer heat twisted, thickly golden-brown-hairy leaves replace the winter leaves after the yellow flowers have appeared in June, but in the UK we keep the broad winter leaves and get either grey or sand yellow tints. For sunny well drained sites.
Phlomis grandiflora NJM 12.005
A potentially large species, rarely seen in cultivation but as hardy as P. fruticosa. This is common in SW Turkey where I found it making huge mounds of pale grey foliage up to 1.8m high by 3m across, but usually smaller. Masses of bright yellow flowers in early summer on long stalks held high above the foliage. For a sunny well drained position.
A small evergreen shrub to about 1m tall, this unusual Turkish species has pale green foliage in winter, but the drier it is in summer the more extreme the leaves become. Summer foliage in the UK climate is narrow and pale yellow-hairy. Yellow flowers in June. Treat this mean, in a well drained, even very dry sunny site.
