Plants with a place in the medicine chest of history. The medicinal mavens gather the herbs, shrubs, and trees that people have turned to for healing and wellbeing across centuries and cultures, grown here for their beauty, their stories, and their long human use.
'Madison' is the cold-hardy Confederate jasmine, the selection that carries the beloved evergreen vine a full zone north of where the tribe usually stops. Vigorous and twining, with glossy dark leaves and the powerfully fragrant, white, star-shaped flowers that make star jasmine famous, this form has proved hardy into USDA zone 7, well beyond the reach of the standard Trachelospermum jasminoides.
Some plants stand quietly in the garden, and some speak. Vitex agnus-castus has been speaking for more than two thousand years, from sun-washed Mediterranean shores to monastery cloisters, from the herbals of ancient Greece to the borders of Southern gardens. In Homer's day the fragrant leaves and lavender flower spikes were woven into ritual garlands. The Romans knew the shrub as the chaste tree, a name wrapped in legend, since the peppery seeds were once thought to cool passion, which earned the seeds the cloister nickname of monk's pepper. The double name says as much twice over: agnus is Latin for lamb and castus for chaste, while the genus Vitex comes from vieo, to weave, a nod to the pliant branches once bent into baskets.
A superior selection of the ancient chaste tree, chosen for the size and color of the bloom. Vitex agnus-castus 'Shoal Creek' is a deciduous large shrub or small tree, native in the species to southern Europe and western Asia and long grown across the South for a long season of summer flower. The palmate, aromatic leaves have now and then been mistaken for those of cannabis, a passing resemblance that gives the plant a certain conversational charm.
A tough, salt-defying seaside groundcover with a serious caveat. Vitex rotundifolia, best known as beach vitex, is a low, prostrate, trailing shrub of the mint family, native to the coasts of eastern Asia, the Pacific islands, and Australia, where the plant binds shifting sand along the shore. Rounded, blue-green leaves about two inches across clothe the running stems, aromatic and slightly spicy when crushed, and spikes of bright lavender-blue flowers open in late summer.
A brightly variegated cousin of the chaste tree, grown for foliage as much as flower. Vitex trifolia, sometimes called the three-leaf chaste tree or Arabian lilac, is a warm-climate shrub of the mint family, native along tropical and subtropical coasts from eastern Africa through southern Asia to Australia and the Pacific. The species name trifolia points to the leaves, usually held in threes, and the selection 'Variegata' edges each gray-green leaflet in creamy white for a cool, luminous effect.
John Bartram collected Xanthorhiza simplicissima from the Carolina mountains sometime before 1776 and brought the plant back to his famous Philadelphia garden, which tells you two things: that yellowroot has been in cultivation for as long as this country has existed, and that people who know plants have always recognized something worth paying attention to here. The Cherokee had known the plant far longer, using the roots, sliced open to reveal a vivid, almost electric chrome yellow, as a dye, a bitter tonic, and a medicine for ailments from mouth sores to stomach complaints. The active compound is berberine, the same antimicrobial alkaloid found in goldenseal, and the roots produce berberine in striking quantity. Xanthorhiza is Greek for yellow root, and the name is no metaphor.
A native tree that bites back, and can numb a toothache. Zanthoxylum clava-herculis, the toothache tree or Hercules' club, is a small to medium deciduous tree of the citrus family, native along the coastal Southeast from Virginia to Florida and Texas. The genus name Zanthoxylum means yellow wood, and the species clava-herculis, the club of Hercules, names the stout, spiny, club-shaped trunk that is the tree's signature.
