About Silene gigantea

Silene gigantea, also known as Giant Catchfly or Gibraltar Campion, is a perennial plant from the Caryophyllaceae family that can reach impressive heights of up to 1.5 meters. It is characterized by its strong, upright stems topped with branched inflorescences of small white or pale pink flowers, blooming throughout the summer.

Care tips

It prefers full sun exposure for optimal flowering, although it tolerates some partial shade. It requires moderate watering, allowing the substrate to dry slightly between waterings, and is quite drought-tolerant once established. It thrives in well-drained soils, preferably sandy or rocky, with a neutral to alkaline pH. A common mistake to avoid is overwatering, which can lead to root rot, especially in heavy soils.
