Plants with a story that begins in Japan. This collection gathers the trees, shrubs, and perennials of Japanese origin and heritage, from garden classics refined over centuries to the wild species behind them.
There is a strange romance buried in this plant's history, and 'Golden King' sits on the male side of it. Aucuba japonica reached England in 1783 as a single female, the yellow-flecked gold dust shrub that Victorians went on to plant by the thousand. Aucuba carry their sexes on separate plants, and for eighty years every aucuba in the country was a clone of that one female, waiting on the famous red berries that never came, because Japan had sealed its borders and no male could be had.
There is a book about Aucuba japonica called A Virgin for Eighty Years, which sounds like a romance novel and is, instead, one of the strangest stories in horticulture. The species arrived in England in 1783 as a single female plant. Aucuba is dioecious, male and female flowers on separate plants, so for the next eighty years every aucuba in English gardens was a clone of that one original female. Gardeners knew the plant was meant to bear bright red berries, since reports came back from Japan, but Japan had closed its borders, no male could be had, and they simply waited.
In Japan they call the shrub tobira, short for tobira no ki, the door tree, because the cut branches were hung in the doorway at Setsubun to turn back demons at the threshold of spring. The broken wood smells rank, which was rather the point: bad spirits, like most of us, would rather not walk through a bad smell. The genus name is kinder and more exact, pitta and sporos, pitch and seed, for the resin that coats the black seeds and glues them to whatever bird carries them off.
Rohdea japonica, the sacred lily or Nippon lily, is a bold, slow, tufted evergreen perennial grown above all for foliage, and this selection carries the darkest leaves of all, an almost black, glossy green that anchors a shaded planting through the whole year and lights up a winter landscape when little else holds. Rather sizeable red berries ripen in tight clusters, half-hidden at the base of the leaves, a quiet second season for anyone who looks closely.
The cast iron plant earned the name honestly. Aspidistra elatior is the toughest of evergreen foliage plants, sending up broad, glossy, dark green blades straight from the soil and holding strong form year round in conditions that defeat almost everything else. A Victorian parlor favorite for surviving gaslight and neglect, the cast iron plant is just as valuable in the deep shade of the garden.
Cephalotaxus harringtonia 'Prostrata' is the spreading Japanese plum yew, a low, wide-growing evergreen prized for lush, dark green, needle-like foliage and an easy way with shade. Where the species and its columnar forms stand upright, 'Prostrata' lays out horizontally, three or four feet high and twice as wide, layering into a handsome evergreen groundcover or low border.
The Sago Palm is not a palm at all. Cycas revoluta belongs to the cycads, an ancient line of seed-bearing gymnosperms far closer to conifers than to any true palm, and the feathered crown is a case of convergent evolution rather than kinship. Cycads carried this same architecture through the age of the dinosaurs, which is part of what lends the Sago Palm such a primeval presence in a modern garden.

Distylium racemosum is the type species of the genus and the most tree-like of the isu trees, an evergreen member of the witch-hazel family, Hamamelidaceae. The genus name comes from the Greek for "two styles," for the paired styles at the center of each small flower, while the species epithet racemosum notes the short racemes along which those flowers are held.
The horticulturist Scott Ogden, in Garden Bulbs for the South, sets the scene: the Japanese roof iris, Iris tectorum, is famous in the native country as a flower for planting on sod roofs, just as houseleeks are used on the cottage roofs of France. In gardens the silky green fans of leaves form large patches, a fine subject for the foreground of a shady border, and in April the ruffled, orchid-like blooms appear among the handsome leaves. In the common form these are a rich mottled blue with white crests; even lovelier, Ogden adds, are the white, yellow-crested blooms of the form offered here.

In gardens the silky green fans of leaves form large patches, a fine subject for the foreground of a shady border, and in April the ruffled, orchid-like blooms appear among the handsome leaves. This is the common form, in which the flowers open a rich mottled blue, veined and freckled toward the center, with white crests.
There is something almost meditative about Nageia nagi. Named from the Japanese word nagi, meaning both calm and to mow down one's troubles, this ancient conifer carries a quiet gravitas few trees can match. At the Nyakuoji Shrine in Kyoto a sacred nagi tree has stood for centuries, believed to cut through hardship and leave peace in its wake, and sprigs of nagi have long passed between lovers as a token of steadfast devotion, the leaves too tough and resilient to tear easily, a metaphor that has endured for a thousand years.
Grown for the leaf rather than the flower, 'Goshiki' is the most colorful of the holly osmanthus. The name means five colors in Japanese, and the spiny, holly-like evergreen leaves earn it: flecked and mottled with cream and yellow against dark green, and flushed at every new growth with startling pink and orange that slowly settles to gold and green. The species name heterophyllus, from the Greek for different-leaved, fits the whole clan, whose juvenile leaves bristle with holly teeth while older ones smooth to entire margins.
Among the false hollies, 'Rotundifolius' is the gentle contrarian. Where the species arms the youthful leaves with fierce holly spines, this old form lays them down entirely: the leaves are small, thick, and rounded, nearly circular and spineless, a heavy, puckered dark green that reads more like boxwood or a miniature bergenia than an osmanthus. The oddity is the whole appeal, a curiosity that stops a plantsman mid-path.
Patrinia scabiosifolia 'Nagoya' is a tough, upright perennial from the meadows and grassy hills of East Asia, grown for airy, flat-topped heads of tiny golden-yellow flowers held high on wiry, branching stems. The species name scabiosifolia points to the deeply lobed basal leaves, which recall those of a scabious, and the whole plant reads as a chartreuse-gold answer to Queen Anne's lace, lending height and a see-through veil to a summer border. In Japan the species is one of the classic seven flowers of autumn, and 'Nagoya' is a garden selection prized for reliable, compact performance.
Podocarpus macrophyllus, the yew pine, is a familiar evergreen conifer grown as a shrub or small tree across the southern United States, valued for dense, dark, strap-like leaves several inches long and a tidy, upright frame. 'Okina' is the variegated form, a relatively recent introduction from Japan, whose new growth emerges creamy white before settling to soft green.
This low-growing form of Podocarpus macrophyllus is a compact, spreading evergreen with flat, needle-like leaves that spiral tightly around the stems. Where the ordinary yew pine climbs into an upright shrub or small tree, this selection stays low and horizontal, building a dense, glossy green mat of steady year-round texture and structure.
Polygonatum odoratum 'Variegatum', the variegated Solomon's seal, is one of the most graceful of all shade perennials, an Old World cousin of the native Solomon's seals grown for luminous, cream-edged foliage on arching stems. Each lance-shaped leaf carries a soft green center rimmed and streaked in creamy white, and the new stems flush a warm rose before greening.

Picture a midnight-green fountain unfurling in a woodland garden: that is Polystichum polyblepharum, the Japanese tassel fern. Native to Japan and South Korea, this evergreen fern forms elegant, shuttlecock-shaped clumps of glossy, bipinnate fronds to eighteen or twenty-four inches tall and wide, bringing shimmering texture and structure to shady corners. In spring the fiddleheads twist back on themselves, like silk tassels, before straightening into perfectly arching blades, lending a touch of theatrical grace to the early-season garden.
Pyrrosia lingua 'Kei Kan' is a fern for people who think they do not like ferns. Nothing here is lacy or feathery. The fronds are thick, leathery, and strap-shaped, and in this selection the tips fork and crest into ragged, comb-like divisions, the feature that earns the Japanese name Kei Kan, meaning cockscomb. The overall effect is closer to a piece of green leather sculpture than to the soft filigree most people picture when they hear the word fern.
