The tropics, grown against the odds. Sub-tropicals bring bold leaves, vivid flowers, and a whiff of the jungle to gardens well north of the frost line, thriving through a hot Southern summer and, with a little shelter, holding on through the cold.
A small, bright green agave with a clean white stripe down the center of each short, broad, toothed leaf, Agave lophantha 'Splendida' is a compact, clumping selection of a species native to South Texas and Mexico. The variegated rosettes stay neat and low, a jewel-box agave for a trough, a container, or the front of a hot, sunny bed.
The genus name Dietes comes from the Greek for "having two relatives," a botanist's nod to the plant's kinship with both Iris and Moraea, near neighbors in the iris family. The species epithet bicolor means simply two-colored, for the soft yellow petals brushed with a dark thumbprint at the base. Between the two words, the whole plant is named for doubleness: two kin, two colors.
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.

Dianella tasmanica 'Variegata' is a strappy evergreen perennial grown above all for foliage: arching, sword-shaped leaves boldly striped in white and green that stay dense and upright through the season and lend crisp, year-round structure to a bed. In spring and early summer, airy panicles of small, star-shaped, blue to violet flowers rise on wiry stems above the leaves, followed by glossy, deep blue berries that gleam against the pale striping, an unusual and long-lasting ornamental touch that gives the plant a second season of interest.
Grevillea rosmarinifolia is a fine-textured Australian evergreen, a rounded to semi-prostrate shrub whose narrow, deep green leaves look uncannily like rosemary, giving the plant both the species name and a handsome, needled presence the year round. The likeness is only skin-deep, for this is a member of the protea family, Proteaceae, worlds away from any herb.
Few tender shrubs work as hard for as long as the lantanas, and Lantana camara 'Hybrida' distills the whole genus down to a single clear note of yellow. The species belongs to the verbena family, Verbenaceae, and hails from the West Indies and the warm reaches of Mexico south through tropical America, where the plant scrambles along roadsides and clearings in a haze of nectar and butterflies. The genus name is a borrowed one: Renaissance botanists lifted 'Lantana' from an old Latin name for the wayfaring tree, Viburnum lantana, whose domed flower clusters the lantana blooms happen to echo. The epithet camara is murkier, glossed variously as a vaulted chamber or a small boat, the true meaning long since lost to the record.
Every so often a plant arrives not from a breeder's bench but from a neighbor's yard, and Lantana camara 'Miss Huff' is one of those happy accidents. The selection was found in cultivation near Athens, Georgia, in the garden of the Miss Huff for whom the plant is named, and introduced to the trade by the former Goodness Grows Nursery. What set this lantana apart was cold tolerance: where most of the tribe sulk and die at the first hard freeze, 'Miss Huff' has proven the hardiest lantana in commerce, with well-established clumps shrugging off brief dips to a few degrees below zero and returning faithfully from the root even in zone 7.
Where the shrubby lantanas stand up, Lantana montevidensis lies down and travels. This is the trailing lantana, a low, weeping member of the verbena family, Verbenaceae, native to the warm grasslands of southern South America, from southern Brazil across Uruguay and Paraguay into Argentina. The species carries a place name in the epithet: montevidensis means of Montevideo, the Uruguayan capital near which the plant was first gathered and described, so the botanical name is really a small geography lesson tucked into Latin.
