Members of the Tunica genus are low growing hardy perennials that have recently been reclassified as belonging to the Petrorhagia family.
They have feathery foliage and bloom in the summer with flat purple or pink flowers.
Common varieties of Tunica grown in the garden include Tunic Flower, Hairy pink, Saxifrage Pink, and Coat Flower.

When growing Tunic flower from seeds it is best to sow them into flats first. This can be done in either spring or autumn.
When sowing in spring, sow the Tunica seeds in a flat and lightly cover, next put the flat in a plastic bin bag and place in the fridge for three weeks. Next sink the flats into a shady part of the garden and cover with glass, water occasionally to keep the soil moist. The germination period of Tunica seeds is from two to 10 weeks.
Once seedlings emerge transplant them into a sunny part of the garden about 10 to 15 cm apart. Ideally the soil will be limy and have good drainage.
Members of the genus such as tunic flower and coat flower pretty much look after themselves. If you require more Tunica plants then propagate by dividing them in the spring.
