From early summer to late fall, the flowers are born in profusion among narrow, smooth, 2-in/5-cm-long leaves, which are up to V2in/13mm wide. The flowers grow singly in the axils of the leaves, and each flower, which lacks petals, consists of a red tubular calyx lin/2.5cm long, with a white and purple mouth. It takes only a little imagination to see the resemblance to a cigar or cigarette with ash at the tip.

Another good species for growing indoors is Cuphea hyssopifolia elfin herb or false heather. This slightly larger, the shrubby plant has small trumpet-shaped flowers, with a green tube and petals of pink, white, or most commonly, pale lilac with deeper mauve veining.  Lack of light will make the leaves appear dull. Move the plant to a brighter position, where leaf edges will redden.
