Plant Details

These New World natives are grown chiefly for their tubular, tightly clustered flowersor, in the case of Justicia brandegeeana, for showy spikes of bracts. Blossoms of all species attract hummingbirds. Leaves are paired, opposite each other on the stems.

american water willow

justicia americana

  • Perennial.
  • Zones US, MS, LS, CS, TS; USDA 6-11.
  • Aquatic species native to eastern half of U.S. Upright, 15 inches stems are clothed in willowlike deep green leaves with a white midrib.
  • Small, white to pale violet flowers with splashy purple markings appear atop stems from early summer into fall.
  • Spreads by creeping rhizomes to form large colonies.
  • Plant at edge of pond for a natural look; grows best in shallow water or very moist soil.
  • Full sun.

yellow justicia, brazilian plume

justicia aurea

  • Evergreen shrub.
  • Zones CS, TS; USDA 9-11.
  • From Mexico and Central America.
  • To 610 feet tall and 68 feet wide, with dark green leaves to 1 feet long, half as wide.
  • Blooms in summer; bright yellow blossom clusters reach up to 1 feet long and look something like ginger flowers.
  • Remove faded flowers to prolong bloom period; cut whole plant back hard in spring.
  • Watch for snails.
  • Best in partial shade.
  • Moderate water.

shrimp plant

justicia brandegeeana (Beloperone guttata)

  • Evergreen shrub.
  • Zones CS, TS; USDA 9-11; elsewhere as annual or indoor/outdoor plant.
  • Native to Mexico.
  • To 34 feet high and wide.
  • Apple-green, oval to elliptic leaves to 2 inches long.
  • Tubular white flowers spotted with purple are enclosed in overlapping coppery bronze bracts to form compact, drooping, jointed-looking spikes 3 inches long (eventually lengthening to 67 inches.).
  • Spike formation somewhat resembles a large shrimp.
  • Blooms mainly from spring to fall, sporadically rest of year.
  • Chartreuse has chartreuse yellow bracts that sunburn more easily than the coppery kind.

Good in pots and for close-up planting near terraces, patios, entryways. To shape, pinch young plants continuously until compact mound of foliage is obtained, then let bloom. To encourage bushiness, cut back stems when bracts turn black. Leaves often drop in cold weather or if soil is too wet or dry. Give moderate water (less in winter) and feed with a balanced liquid fertilizer monthly during active growth. Takes full sun, but bracts and foliage fade unless plant is grown in partial shade. Give at least half-day shade in hottest climates.
