Gerardia hardy perennials

Gerardia hardy perennialsThe Gerardia are hardy perennials that form pyramidal bushes bearing Pentstemon-like flowers, thickly set and varying in colour from light pink to dark purple. A peat soil suits them best. They may be propagated by cuttings placed under glass, but are best grown from seed.

July is their flowering season. Their height differs from about 1 to 2 feet.
