Sisyrinchium

An interesting group of plants belonging to the Iris family. In the wild they are found in the Americas where they prefer moister soils. Much more adaptable in cultivation, a well drained soil is essential but still preferring a soil that does not dry out. All are clump forming and division is advisable every few years to maintain vigour. S striatum is a reliable self seeder in the border or dry garden, whereas the variegated form can only be increased by replanting the non-flowering fans. The smaller forms make ideal rockery or edging plants.
