The best known of the European natives, Lilium martagon and its variants have the greatest range of any species. Preferring calcareous soils, Lilium martagon can find a home in every garden provided some lime is added yearly to the soil. Not liking to be disturbed, it will often refuse to send up a stem the first season after being moved. The Turk's Cap flowers are small, but as many as 50 or more can appear on the 4 foot stem of a mature, settled bulb. Carrying a light "wild flower" scent, they do well in shade as well as full sun, of which the latter tends to keep stems from reaching their full potential.
