Paesia scaberula (new)
A very pretty little fern from New Zealand with tripinnate very finely divided fronds. A coloniser in the wild, this is much better behaved in cultivation in colder areas like the UK and makes a neat clump. Rickard rates it as Zone 7 in Central England, so clearly tougher than we think, though mulch the rhizomes with straw if you're scared.
Parablechnum cordatum (syn. Blechnum chilense)
A particularly robustly handsome South American evergreen fern producing very bold, very leathery, darkest green fronds with many opposite pinnae. Slowly spreads to form patches, with fronds reaching about 1m, or up to 1.5m if moist and sheltered. Humus rich acid to neutral soil in semi-shade, or sun if moist. Hardy throughout the UK.
Parathelypteris beddomei (new)
A ground covering fern from Korea, rarely seen in cultivation, though very hardy and easily grown in moist woodland conditions. Tapering fronds with up to 30 or more pairs of pinnae rise from a creeping rootstock. A good ground covering species only 45cm tall, good for mingling around taller and bolder subjects.
Pellaea viridis (new)
A distinctive handsome, evergreen fern with vivid, glowing green fronds, composed of angular pinnae and contrasting black stipes, to about 60cm. Full hardiness unknown, it requires very well drained compost and good light. Happy overwintered in a cool conservatory.
Phymatosorus diversifolius (syn. Microsorum)
From Australia and New Zealand this Polypodium relative is sometimes found as an epiphyte on imported tree fern trunks. Can form impressive colonies as a climbing plant on trees, banks or walls in mild areas, even up to 5m off the ground. Glossy evergreen fronds are either simple, as juveniles, or pinnatifid, as adult. Not tried outside here yet but excellent on the West coast.
Polypodium 'Whitley Giant'
Previously very obscure, but now getting about a bit, this is close to P. cambricum, though has longer and broader fronds, making for a very handsome polypody. Pinnatifid fronds to 40cm from a gently creeping rootstock, eventually forming a nice patch. For reasonably well drained, even rocky soil in semi-shade.
A most unusual species with thick textured, leathery, shiny, dark-green fronds. Forms a good clump in time with a height of about 30cm. Rarely seen but perfectly hardy in inland UK and excellent in maritime areas, as it is in the wild state on the very coastal fringe of N. America from B.C. to Baja. For a shaded site.
Polystichum aff. manmeiense (new)
From a Nepalese collection, this makes a dark evergreen species with thick textured arching shiny fronds. Usually a fairly small fern though very rarely seen in cultivation. For a sheltered humus rich spot.
Polystichum lepidocaulon (new)
A very handsome fern, though not the hardiest, this is best long-term in a sheltered position with a little overhead cover if possible, or in milder areas. Often from maritime parts of Eastern Asia this has evergreen, shiny, leathery, pinnate fronds 30 - 60cm long. Rarely available.
Polystichum neolobatum (new)
One of the most desired of the genus and a particularly good looking evergreen species with very thick textured and prickly edged, glossy green fronds, the stipe and rachis covered in dark-brown scales. Fronds are slightly metallic silvery when young. Many plants sold as this are actually related species. Height 45cm. For some shade and humusy soil.
An impressive Japanese evergreen fern with very glossy, rich-green, divided fronds, beautiful when unfurling in the spring covered in golden bristles. Ht 60cm. Shade/semi-shade in humusy, well-drained soil.
Polystichum setiferum 'Cristatopinnulum'
A very old form of our native Soft shield fern found in Dorset in 1878. The tough but feathery, heavily divided fronds have little fan shaped pinnules and reach up to 90cm high. Rarely offered.
Polystichum setiferum 'Plumoso-divisilobum Bland' (new)
One of the finest of the setiferum types and rarely offered, this reaches 60cm high, with highly divided fronds, quadripinnate at the base rising to tripinnate at the tip. Pinnae overlapping at the base and not at the top. Easy in ferny conditions.
Polystichum setiferum 'Plumosum-Bevis'
Until very recently this was a very expensive rarity. Now the wonders of micro-propagation have brought you these. One of the finest of all ferns, with splendidly elegant, dark-green, uniformly and perfectly divided fronds, ending in a drawn out, tapering tip, arching out from the crown. Height up to 1.2m. Easy in any well drained, good soil in semi-shade/shade.
Polystichum wawranum (new)
Related to the magnificent P. vestitum and like it from New Zealand, this is a little smaller growing with slightly lighter green, drawn-out, triangular evergreen fronds with a different 'look'. For a shaded, moist and humusy site. Rarely seen in cultivation in the UK.
Polystichum x dycei (new)
A rare hybrid between two excellent species (proliferum and braunii) this forms one of the very largest of all Polystichum, up to 1.2m tall, making individual crowns of beautifully dissected lance shaped, bipinnate fronds. Can produce small plantlets at the tips of the fronds as per P. proliferum. A tough and easy large fern for shade to semi-shade.
Not often seen in cultivation, yet easily grown in acid or alkaline conditions, this hardy evergreen fern from India, China and Taiwan bears glossy, lance shaped, hard textured fronds on a plant 30 to 45cm tall. The silvery green patina to the fronds is distinctive and attractive. For a semi-shaded position in humusy soil.
Polystichum yunnanense (new)
A very robust, hardy and easy species with narrowly triangular glossy green fronds to 90cm long, the stipes (stalks) with very obvious brown scales. From the Sino-Himalayan region, this is a strong and easy species in UK cultivation, though rarely offered or grown.
Pteris incompleta (new)
A rarity from very few sites in the Western Mediterranean and the Canaries, Azores and Madeira where it inhabits Laurisilva forests. A handsome species, the fronds with an elegantly drawn out apex to the lamina and also the pinnae. These fronds have black bases to the stalks and can reach up to 1.5m long in ideal conditions. For mild gardens or pot culture.
