About 10 species from around the Mediterranean, southern Europe and western Asia. They are subshrubs resembling Helianthemum but generally smaller-flowered with sterile outer stamens.
Less hardy than Helianthemum so requiring alpine house protection, but see hardiness under F. procumbens below. Well drained sandy and/or limey soil and a sunny position are needed, sheltered if tried outside. Propagation by seed in spring, cuttings in summer. Flowers very fleeting but borne in succession.
