The garden under the canopy. Shade is not a problem to solve but a place to plant, and these are the ferns, foliage plants, and quiet bloomers that make the cool, dim ground beneath trees and walls into one of the loveliest parts of a garden.
Thelypteris acuminata is a handsome evergreen fern from the woodlands of Japan and eastern Asia, grown for glossy green fronds that arch softly and hold their color through the year. Unlike the many deciduous ferns that vanish in winter, this species keeps a steady, structural presence in the shaded garden, one of the reasons the plant is prized where an evergreen fern is wanted.
The southern shield fern carries a longer pedigree than most ferns in cultivation. The type specimen was collected by Alexander von Humboldt and Aimé Bonpland near Cumanacoa, in the cloud-shrouded country around Caripe in northeastern Venezuela, during their five-year expedition through the equinoctial Americas. Decades later the German botanist Carl Sigismund Kunth, Humboldt's assistant in Paris and the man who would spend years describing the ten thousand and more specimens the explorers shipped home, became the namesake when Nicaise Auguste Desvaux formally described the species in 1827 as Nephrodium kunthii. C.V. Morton moved the fern into Thelypteris in 1967, and recent molecular work (Fawcett and Smith, 2021) has shifted the name again into Pelazoneuron, though the older binomial remains the one in common horticultural use.
In July, when most of the shade garden has settled into a holding pattern of foliage and waiting, Aesculus parviflora opens for business. The timing is the first surprise. The flowers are the second. Each panicle is a foot or more of tightly packed white tubular blooms with conspicuous pink-red anthers projecting beyond the petals, the whole spike held upright above the foliage like something assembled by a botanical committee that could not decide between elegant and extravagant and chose both. A mature colony in full bloom in midsummer is among the more spectacular events available to the shade gardener, and the hummingbirds and swallowtails arrive reliably.
A wide-spreading, suckering, multi-stemmed deciduous shrub of slow, deliberate growth, Aesculus parviflora var. serotina carries the same upright white bottlebrush flowers as the bottlebrush buckeye, but opens them two to three weeks later, well into the heat of summer. The overall shape is irregular and almost stratified, the branches layering horizontally, and the medium to dark green leaves turn a clear yellow in fall.
A hardy evergreen ginger of unsettled name, this Alpinia forms dense, upright clumps of lance-shaped leaves that hold their fresh green right through the year in a mild climate, bringing a lush, tropical structure to the shade garden. In the warm months, bright yellow flower spikes rise above the foliage for an unexpected lift of color in deep shade.
A small shrub built like a miniature tree, Ardisia crenata rises on one clean stem to two or four feet, occasionally six, and carries a single tier of glossy dark green leaves at the top like a parasol. The leaf margins are thick and scalloped, waved just enough to catch the light along the edge. Small white to pale pink stars hang in nodding clusters in late spring, lightly scented, and are followed by the reason anyone actually grows the shrub: tight bunches of round, lacquer-red berries that hold from autumn straight through to the next flowering.
The uncommon white-berried form of coral ardisia, Ardisia crenata 'Alba' is a small, neat evergreen shrub of glossy, scallop-edged dark green leaves, hung in fall and winter with clusters of round white berries in place of the usual coral red. The pale fruit and shining foliage give a long season of quiet interest, indoors in a bright room or out in a shaded, frost-free garden.
Low, shining, and quietly territorial, Ardisia japonica travels on slender underground stems and knits a dense evergreen carpet eight to twelve inches high across ground that most groundcovers refuse. The leaves are gathered in loose whorls near the tips of the stems, glossy and finely toothed, dark enough to read as almost black in deep shade. Small white to pale pink stars nod beneath the foliage in midsummer, easy to miss unless you kneel, and the berries that follow ripen coral red and hang on through winter, often still bright when the next year's flowers open.
Ardisia japonica 'Hakuokan' is a jewel of the Japanese shade garden, a low evergreen groundcover whose small, glossy, leathery leaves are edged in a clean band of creamy white. The green species, called yabukoji in Japan and marlberry in English, has grown wild in the woodland understory of Japan, Korea, China, and Taiwan for ages, spreading quietly by underground runners into knee-low colonies. 'Hakuokan', a name that reads roughly as white royal crown, is a variegated selection prized by collectors, slower and more compact than the plain species and all the more luminous for the pale margin that catches light in a dim corner.
Ardisia japonica 'Hinode' is a variegated form of the Japanese marlberry, each glossy, dark green leaf marked with a broad gold band down the center. Low and slowly spreading, this evergreen carpets shaded ground at eight to twelve inches, lit by the gold variegation and dotted in fall with bright red berries that hold into winter.
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.
A boldly striped form of the cast iron plant, Aspidistra elatior 'Variegata' carries the same broad, leathery, evergreen blades, each brushed lengthwise with bands of creamy white over deep glossy green. The variegation lights up a shaded corner, and the toughness is all there too: this is a near-indestructible evergreen for difficult, low-light places.
Aucuba chinensis is the lesser-known Chinese cousin of the familiar gold dust plant, a rare, broad, evergreen shrub for deep shade. The thick, leathery, dark green leaves are coarsely toothed and dusted with scattered yellow flecks, holding their color year round and bringing a glossy, tropical-looking presence to a shaded bed.
Most aucubas demand a matchmaker, a male plant set near a female before a single red berry will form, but Aucuba japonica 'Rozannie' needs no such arrangement. This compact, deep green selection is self-fertile, setting large, glossy scarlet fruit without a separate pollinator, and fruiting even more heavily when a male happens to grow nearby. Add to that lustrous, coarsely toothed, unspotted foliage and a tidy three-to-four-foot frame, and 'Rozannie' becomes one of the most useful aucubas for a shaded garden.
Aucuba japonica is one of the great problem-solvers of the shade garden, a glossy broadleaf evergreen that thrives in the dry, difficult shade where few other shrubs will, and var. borealis is the toughest of the clan. Drawn from the cold northern reaches of the plant's Japanese range, this small-leaved form was selected for hardiness, holding very shiny, dark green, leathery leaves through winters that would burn a common aucuba. The genus name is a Latin rendering of the Japanese aokiba, for the ever-green leaves.
This is one of the quiet mysteries of the Woodlanders collection, a narrow-leaved evergreen aucuba received years ago from the U.S. National Arboretum under the name Aucuba himalayica, and quite possibly the slender japonica form known as 'Longifolia' instead. Either way the plant is a striking departure from the usual aucuba, trading broad, spotted leaves for long, willow-like, finely serrated blades of glossy dark green. Woodlanders has not seen this aucuba offered anywhere else, which makes the plant a true collector's piece whatever the correct name proves to be.
Hardy begonia is the surprise of the shade border: a true begonia that survives a cold winter. Begonia grandis carries large, pointed, olive-green leaves lit with red veins and flushed deep rose-red beneath, and in late summer and fall hangs loose clusters of soft pink flowers on red-tinted stems, a cool, luminous note when most shade plants have finished.
A twisting, weeping take on the classic boxwood, Buxus sempervirens 'Unraveled' breaks the upright, clipped mold of the genus entirely. The branches arch and twist into a loose, cascading, almost sculptural form, dense with the familiar small evergreen leaves but carried on a frame that drapes rather than stands. A selection from the JC Raulston Arboretum, 'Unraveled' brings a wild, playful edge to a plant usually grown for rigid formality.
Camellia fraterna is a camellia stripped back to wild beginnings, a species from the hills of eastern China far removed from the big, blowsy blooms of the garden japonicas and sasanquas. Where those carry a few large flowers, this one covers slender, upright branches in a snowfall of small, single, white flowers, faintly pink outside and softly fragrant, that arch the stems with their sheer number. The small, pointed evergreen leaves and open, airy habit give the plant an easy, natural grace.
Camellia gigantocarpa is a rare and remarkable species from the subtropical forests of southern China, first documented in the wild in the 1980s in Guangxi Province. The name says the essential thing: gigantocarpa, giant fruit. Where most camellias are grown for flowers, this species is prized above all for the great woody seed capsules that follow them, among the largest in the entire genus.
