Lobelia cardinalis

Cardinal Flower
Campanulaceae (Lobeliaceae)
Perennials

LOBELIA

All are grown for their tubular, lipped flowers, which resemble those of honeysuckle (Lonicera) or Salvia. Annual kinds are low plants for edgings or hanging baskets; perennial sorts are larger, vertical-growing plants with flowering stalks that rise above the foliage.

Lobelia cardinalis

This perennial is native to the eastern United States and to a few sites in the mountains of the Southwest. Erect, single-stemmed plant grows to 2–4 ft. high and 1 ft. wide. Sawtooth-edged leaves are set directly on the stems. Spikes of flame red, inch-long flowers show up in summer.
