Silene nocturna aka Mediterranean Catchfly

Silene nocturna is a rare annual herb in the Caryophyllaceae family, found in various habitats such as ditches, wastelands, rocky areas, and forests. It has a self-supporting growth form, simple broad leaves, and can grow up to 0.39 m with erect, usually branched stems. Its flowers are crowded in raceme-like cymes, with pink bifid petal-limbs, and oblong-obovoid calyxes pubescent with ascending hairs. The plant might be poisonous, and can be controlled using cultural and mechanical methods or herbicides. As a houseplant, Silene nocturna needs regular watering, long-lasting direct light, and well-draining soil. Repotting it each time it doubles in size eliminates the need for added fertilizers.
