The Lenten rose is suited to shaded or part-shaded positions, in soil rich in
humus. Cultivated varieties have a wide array of colours. German planters began breeding
H. orientalis in the mid-19th century, enhanced by new material from the Caucasus via St Petersburg Botanic Garden. New varieties were soon introduced to the United Kingdom. Interest peaked in the late 19th century, but the genus had fallen out of favour by the 1920s. The Lenten rose was revived in horticulture in the 1960s by
Helen Ballard, who bred many new varieties. Cultivated varieties can have white, green, pink to maroon and purple or spotted flowers. ==References==
