Million bells

A compact, fast warm-season annual from Mexico and Guatemala (despite the "French" name) grown as bedding, edging, and container color. It typically reaches 6 to 12 inches tall with single to fully double, 1-2 inch fragrant flowerheads in yellow, orange, red, and bicolor over aromatic, deeply pinnate toothed foliage. Blooms June to frost in full sun, is low-maintenance, and is one of the few annuals deer tend to leave alone. On the name: Kew and GBIF now both fold the French marigold into Tagetes erecta, the African marigold, and treat Tagetes patula as a synonym of it. The two are still sold and bred as distinct garden plants, so this page keeps the familiar name.

A low, mat-forming succulent annual from Brazil, Argentina, and Uruguay, grown for its ruffled, rose-like flowers above clusters of cylindrical, fleshy leaves on reddish stems. From June to frost it carries 1-inch single, semi-double, or double blooms in red, rose, orange, yellow, or white that open in sun and close on cloudy or rainy days. Missouri Botanical Garden PlantFinder rates it for poor, dry, well-drained soils in full sun, where its drought tolerance lets it thrive in hot spots that defeat many other plants.

A compact, frost-tender warm-season annual from Mexico and Central America grown for its dense, fuzzy, thread-like ("flossy") flower clusters - most famously in soft true blue and lavender-blue, the trait that sets it apart from almost every other bedding annual, plus pink and white forms. It mounds into a clumping cushion 6 to 12 inches tall and about as wide, blooming from early summer until frost over soft, heart-shaped, slightly hairy leaves. It is easy and rewarding bedding, edging, and container color in full sun to part shade with steady moisture, but it is strictly look-don't-eat: the foliage and stems contain hepatotoxic pyrrolizidine alkaloids and are toxic if ingested.

Globe amaranth is a warm-season annual in the amaranth family (Amaranthaceae), grown for its round, clover-like flower heads of papery, long-lasting bracts: bright magenta in the species (Missouri Botanical Garden PlantFinder), with cultivars in purple, pink, red, lilac, violet, and white. The true flowers are tiny white to yellow trumpets tucked among the bracts. Kew's WCVP gives its native range as Mexico, Central America (Guatemala, Honduras, Nicaragua, and Panama), and tropical South America (Colombia, Ecuador, Guyana, Bolivia, and Brazil). NC State Extension and Missouri Botanical Garden describe a compact, upright plant 6 to 24 inches tall and 6 to 12 inches wide that flowers from June until frost, takes heat and drought once established, and makes a classic everlasting: the heads keep their color when cut and dried. It is frost-tender. NC State Extension rates it winter hardy only in USDA zones 9 to 11, where it can be grown as a perennial; everywhere else it is sown or planted after the last frost and grown for a single summer, which is why both sources list it as an annual for zones 2 to 11. It is a Gomphrena, not an Amaranthus: the amaranth in its name is the family it shares with love-lies-bleeding and the grain amaranths. It also shares the name bachelor's button with the cornflower (Centaurea cyanus), a different plant.
