Bergenia cordifolia (often treated by botanists as a synonym within B. crassifolia) is a tough, evergreen perennial native to the Altai Mountains, southern Siberia and Mongolia, grown for its bold, heart-shaped leathery leaves that flush red-bronze through winter and its deep pink flower spikes in early-to-mid spring. It is one of the most tolerant groundcovers in cultivation - enduring deep shade, poor soil, drought, and hard continental cold (commonly rated to USDA Zone 3 in US horticulture; RHS rates it H7, hardy below -4°F). The honest catch is its shallowly creeping rhizomes: in mild, moist climates they can colonise well beyond the intended planting, and the large, persistent leaves trap fallen debris and are notoriously attractive to slugs and vine weevils.

Mondo grass is a stoloniferous, evergreen perennial in the Asparagaceae (not a true grass despite its grass-like leaves), native to China, Japan, India, Nepal, and Vietnam, grown as a fine-textured, low groundcover that forms a dense, weed-suppressing turf of dark green foliage. It tolerates deep shade and dry spells once established, making it popular for difficult spots under trees and along pathways. The honest catch is its aggressive spread by underground stolons - in warm zones (8-10) it readily colonises beyond its intended boundary and needs hard edging - and its attractive metallic-blue berries contain steroidal saponins that are mildly toxic if eaten.

The classic cool-season bedding plant, grown for 2-4 inch flattened "face" flowers in nearly every color, usually marked with a contrasting dark blotch and central whiskering. A garden-origin hybrid (not a wild species) treated as a short-lived perennial run as a cool-weather annual or biennial - it blooms hardest in spring and fall and inevitably succumbs to summer heat. The Missouri Botanical Garden lists it as the top-selling winter bedding plant in the deep South.

A tender perennial grown almost everywhere as a warm-season bedding annual, prized for blooming reliably from June to frost in white, pink, red, and bicolor. Its thick, waxy dark-green-to-bronze leaves minimize water loss, giving it real tolerance for hot, humid summers. Compact and mounding at 6 to 12 inches, it is a workhorse edger and container filler in sun-dappled part shade.

Aubrieta (Aubrieta deltoidea) is a low, mat-forming evergreen perennial in the mustard family (Brassicaceae), native to the rocky hillsides of southeastern Europe - primarily Greece, the Aegean Islands, Crete, and adjacent Mediterranean coasts. It is one of the most reliable spring-flowering ground covers for sunny, well-drained spots: cascading sheets of violet to deep pink four-petalled blooms from March through May, attractive to bees and bee flies. The honest catch is that without a hard cut-back immediately after flowering, plants become woody and bare in the centre within two or three years, collapsing from a tight carpet into a tired, gappy mat.

Felicia amelloides is an evergreen, woody-based perennial subshrub native to a narrow coastal strip of South Africa's Western and Eastern Cape, where it colonises stabilising sand dunes, sandy flats, and rocky outcrops at 0 to 3,280.8 feet. In the garden it delivers a near-continuous flush of sky-blue, yellow-centred daisy flowers on neat mounding growth, typically 12 to 24 inches but capable of reaching about 3.3 feet, making it one of the few true blue-flowered plants for sunny pots and borders. The honest catch is frost-tenderness: it survives only light frost in sharply drained soil and collapses below about 23°F, so outside USDA zones 9-11 it must be overwintered under glass or replaced annually - a real commitment in cool-temperate gardens.
