(Tunica) Petrorhagia saxifraga by Nuuuuuuuuuuul.
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. Following this, 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 (4 to 6 inches). Ideally the soil will be limy and have good drainage.
Members of this 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.
The Tunica genus is small, with around five recognized species.
Tunica is a charming plant for rock gardens and borders, with its low-growing habit and attractive pink flowers.
The most commonly cultivated Tunica species is Tunica saxifraga.
Tunica species are not generally known for fragrance.
Tunica thrives in full sun with well-drained soil. It is drought tolerant and suitable for rock gardens.
Currently, Tunica is not considered invasive in the USA.
Tunica plants can be manually removed by uprooting the entire plant.
The Tunica genus includes perennial plants native to South Africa and Europe. They are admired for their clusters of small, delicate flowers that bloom in spring and early summer. Tunica saxifraga, commonly known as pink rockjasmine, is one of the most popular species.
Grow Tunica from seeds or cuttings, preferably in spring. They prefer full sun to partial shade and well-drained, sandy soil. Regular watering is necessary, particularly during dry periods, but overwatering should be avoided to prevent root rot. Deadheading can help prolong the blooming period.
