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.
A Victorian-era English selection of one of the great trees of North America. The species, Thuja plicata, the western red cedar, is the dominant conifer of the Pacific Northwest coastal rainforest, the tree that towers 150 to 200 feet above the forest floor in old-growth stands of British Columbia, Washington, Oregon, and northern California, with individual specimens documented at over a thousand years old. To the Coast Salish, Haida, Tlingit, Kwakwaka'wakw, and other Pacific Northwest Indigenous peoples, western red cedar is the Tree of Life: the wood used for longhouses, dugout canoes, totem poles, and ceremonial regalia; the bark woven into baskets, mats, capes, and dress; the whole tree a structural and cultural foundation for thousands of years. That natural rot-resistance comes from the same volatile terpenoids that give the crushed foliage a sweet, cedary fragrance, the smell of the Pacific Northwest forest itself.
A dwarf form of one of Japan's legendary Five Sacred Trees of Kiso, the goboku no kinbatsu, a select group of conifers protected by feudal law for centuries, reserved for imperial residences and temple construction, where commoners caught poaching the wood faced execution. The species, Thujopsis dolabrata, is endemic to Japan and known there as asunaro, a name that translates beautifully and a little wistfully as tomorrow it will become hinoki, a nod to the tree's resemblance to the more revered hinoki cypress, forever almost but not quite the more famous tree. Thujopsis is the sole species in the entire genus.
Copper Canyon daisy is a big, aromatic, autumn-flowering marigold from the mountains of southern Arizona and adjacent northern Mexico, grown as much for the scent as the show. Brush against the finely divided, fern-like foliage and the plant releases a strong, distinctive fragrance, a mix of citrus, anise, and marigold that some find intoxicating and others frankly pungent. Tagetes lemmonii builds a soft, shrubby mound three to four feet high and wider still.
Tagetes lucida is the herb that does it all. Known as Mexican tarragon, Mexican mint marigold, pericón, and, in the old Aztec tongue, yauhtli, this fragrant perennial from Mexico and Central America earns every name. The narrow, glossy, deep-green leaves carry a warm anise-tarragon scent and flavor, and in late summer and fall the plant scatters small, single, golden-yellow marigold flowers across a tidy foot-and-a-half mound.
Silver germander is a Mediterranean evergreen grown above all for foliage. Teucrium fruticans wears small, aromatic, gray-green leaves backed in silvery white felt, on pale, white-woolly stems, so the whole shrub reads as a soft silver mound that lights a hot, sunny border and cools the greens around it. A member of the mint family, Lamiaceae, the plant carries the square stems and aromatic foliage of that clan.
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.
