Petromarula is a genus of plants in the family Campanulaceae. There is only one known species, Petromarula pinnata, endemic to the island of Crete in the Mediterranean.[1] [2] The name "Petromarula" means "rock lettuce" in Greek, a reference to the plant's traditional use in salads.[3]
Petromarula pinnata is a robust, medium to tall perennial, minutely hairy above. Leaves mostly in a large basal rosette, pinnate to pinnately-lobed, the lower long-stalked; leaflets oval to oblong, coarsely toothed. Flowers pale blue, 9–10 mm, borne in large rather narrow panicles; corolla with 5 spreading to recurved linear lobes. Capsule opening by 3 pores in the middle. Flowers April–May.[4]
