Oregano

Origanum vulgare
A Mediterranean herbaceous perennial forming a spreading mat of small aromatic leaves + open clusters of small pink-to-white flowers in summer. Strongly attractive to honey bees, bumblebees, hoverflies, and small butterflies; among the best edible herbs for pollinator support. The cultivars used for cooking (Greek oregano, Italian oregano) are selections of this species.

Calendula officinalis
Calendula (pot marigold)
An Old World cottage-garden annual grown for daisy- to chrysanthemum-like flowerheads (3-4 inches across) in bright yellow through deep orange, often with a contrasting darker center disk. In cool climates it blooms over a long summer-to-fall window; in hot summers it tends to languish and may need a midseason cutback to rebloom. The somewhat bitter flowers and lance-shaped aromatic leaves are edible, and the petals lend color to soups, rice, and baked goods.

Mahonia repens
Creeping mahonia
A low, ground-hugging evergreen shrub of the Rocky Mountain West (also called creeping Oregon grape; NC State files it under the synonym Berberis repens). It spreads by underground stems into a holly-leaved mat 12-24 inches tall, with blue-green pinnate compound foliage that flushes bronze-to-purple-red in winter, fragrant yellow flower clusters in spring, and glaucous blue-black grape-like berries in summer. Tough, cold-hardy, and shade- and drought-tolerant once established — among the best evergreen native groundcovers for dry shade.

Agastache foeniculum
Anise hyssop
An upright, clump-forming perennial of the mint family native to the upper Midwest, Great Plains, and into central Canada, named for its anise-scented foliage. From June through September it carries dense terminal spikes of lavender-to-purple two-lipped flowers above square stems and opposite, toothed leaves. The Lady Bird Johnson Wildflower Center flags it as a nectar source with special value to native bees, bumble bees, and honey bees, and it also draws butterflies and hummingbirds.
