Photinia aff. prionophylla

This looks a lot like what Hilliers manual describes as ‘Formosan form’. I'm not at all sure about this identification but a very gorgeous shrub nevertheless - more rounded and compact than the normal P.serratifolia, with broad rounded leaves (to about 3ins across) opening a rich mahogany in early spring, with a soft downy white covering.

The flowers are the normal type.

Easy and adaptable and tolerant of heavy and wet soils.

Aristolochia sempervirens from Carqueiranne, Toulon

A very special form of this species from the South of France with relatively large lush foliage (up to about 3ins long), a more vigorous climbing habit and very refined, richly coloured flowers.

Dominik Frank tells me "this particular form is very hardy, together with an associate from France we established it in cultivation a few years ago. Isolated properly mature specimens can take as much as -12 °C. Actually it isn't native to France, the few feral populations scattered across the Côte d’Azur seem to originate from Algeria."
Very nice indeed.

Helleborus lividus

This Balearic endemic dwarf hellebore is normally very hardy or long-lived unprotected in the garden but these are seedlings of a strong and floriferous plant here at the nursery.

The slight serration in the leaves means there's a good chance that it has some argutifolius in it (which, strictly speaking, would make it a form of sternii) but it is nevertheless a nice small plant with strong silver markings in the leaves and and purple tints in the flowers.

Flowers in late winter and spring. I grow it in dry sunny Mediterranean conditions
£8

Salix bockii

A very unusual willow for its summer/autumn flowering - the catkins are creamy white up to 2ins long on long slender branches covered in small oval grey green leaves.

Frankly it looks nothing like a willow, but is an adaptable small to medium shrub suitable for any not-too-dry soils in sun or semi shade.
£10

Perovskia Filigran

A choicer, shorter plant than the P.atriplicifolia cultivars we normally see and probably a form or hybrid of P.abrotanoides, which is less easy to grow in moist mild climates.  The silver foliage is very finely cut, the stems are white and the flowers are intense blue.

I’ve not yet worked out how to get the best from it but a very dry site with maximum exposure is probably the key. Very cold hardy.
£8

Pilea and Lecanthus

Pilea are probably better known as houseplants but some of the Asian species seem to be hardy in moist woodland conditions.

Pilea sp. DS 834

Another luxuriant woodland ground-cover, more like the tropical P.cadieri with serrated, silver splashed leaves.

£7

Pilea aff. plataniflora Pelling PB02-518

A low bushy woodlander with smooth elliptical fresh green leaves with three prominent veins, and branching sprays of tiny creamy flowers.
For damp shady conditions
£7

Lecanthus aff. peduncularis

A peculiar little woodlander – a member of the nettle family (but non-stinging) making a fresh green ground-cover. The flowers are individually tiny but gathered into pale fruit pastille-like heads, reminiscent of a Dorstenia.

More of a curio than a great beauty but I really like it.
£7

Aristolochia baetica

A small climber from southern Spain and Portugal that can be seen there twining about among the shrubs with its grey heart shaped leaves and maroon pitcher-shaped flowers. It’s one of the more vigorous and obvious of the Mediterranean species and worth trying in a sheltered sunny well-drained site, but it isn’t very hardy. I recommend planting it under a smallish shrub like a Cistus or broom and letting it grow forward among the branches. Even if it gets frosted the roots will usually regenerate

£10

Bomarea aff. caldasii

There seems to be some confusion about exactly whether caldasii is in cultivation but with funnel shaped orange and red flowers this appears to be something very similar. The inner petals are orange/yellow, the outer are coral red. There are no other markings but the black anthers are prominent.

Untried outside, but like many Bomarea, the roots go so deep that they are unlikely to freeze in a normal UK winter. Climbing to about 2m, and dying down in winter.

£12

Viburnum cylindricum

An evergreen species grown for the unusual greyish cast to the foliage and panicles of creamy flowers in summer. Bloomy black fruits.  An uncommon large shrub – excellent on chalk. £16

Two plants for dry shade

Strobilanthes nutans

A really nice change from the better known upright purple flowered species – this one trails over the ground and is seen at its best in a shady raised bed (or a hanging basket? Why not?) with it’s pure white, hop-like inflorescences dangling over the side.

Hardy so far here and unusually classy.
£8

Euonymus fortunei Wolong Ghost

Very different to other forms of fortunei in cultivation – this is a creeping/climbing plant with relatively narrow dark green leaves, the veins picked out in white.

Makes an excellent ground cover in dry shade
£8

Some Shrubs and Larger Perennials

Colquhounia coccinea

Pronounced Cohoonia, a very striking and exotic species, hardy and easily grown in a sunny, well-drained but not parched situation. Stems may die back during a hard winter but grow back during the summer in time to flower in the autumn.

Flowering relatively late, this species can be shy flowering if it does not get enough sun or if there is an early frost, but well worth persevering with.
£16

Buddleja limitanea

A relatively small species which may or may not be a form of forrestii. The foliage resembles davidii but is smaller and neater and more evergreen. The flowers are fewer but larger and bell-shaped and of soft mauve with the usual orange eye. The fact that it doesn’t get huge should be enough of an incentive to grow it for many people
£12

Caryopteris (Tripora) divaricata

A lush green upright bush, dying down completely in winter. The late flowering is the same but the flowers themselves are larger, rich blue, and much more interesting. Another purveyor of rare plants describes the flowers as merely ‘harmless’ which I think is rather a shame. They’re not huge or especially plentiful, but they are jolly pretty. Hardy and adaptable.

Very different to the familiar grey twiggy subshrubs (C. x clandonensis and the like) and this is now classified under another name - Tripora. 

£9

Jasminum fruticans

A lovely small shrub with fresh yellow (unscented) flowers in summer and neat little pinnate leaves. Makes a twiggy bush not more than three feet high here. Easy in any sunny spot in the garden where it won't be overwhelmed by boisterous neighbours. I have no idea why this is not very popular indeed.
£8

Some Small Perennials

Anemarrhena asphodeloides

A bit like an asphodel, making a grassy clump, with spikes of narrow violet flowers on slender stems in summer.

As far as I know it has no close relatives and is a bit of a botanical oddity. Nice though, in an understated way, and not at all difficult to grow in a well-drained spot in sun.
£7

Chlorophytum chinense

A small hardy Chinese relative of the common spider plant with similar narrow grassy leaves (not variegated) and sprays of small white flowers. Pretty in a very understated way - rather like an Anthericum
£7

Anemone sylvestris

A common and widespread European alpine eventually making large clumps of deeply cut dark green foliage up to about 6ins high, with individual nodding white anemone flowers above. Easy and hardy in a sunny well-drained spot.
£7

Aphyllanthes monspeliensis

Masquerading as a low grey rush or sheep's fescue, this mop-top suddenly bursts into life in late spring with bright blue flowers at the tips of its ‘leaves’. (The name means something like 'flowers without leaves')
£8

Lathyrus linifolius

An attractive low species with narrow leaflets and short clusters of pale lavender flowers. Any well-drained soil in sun
£7
