Silene stenophylla

Sea campion comes from bright, open habitats and does best in full sun. It can tolerate partial sun but favors direct sunlight for optimal growth. This plant, which may be annual or biennial, is known for its sun-loving nature.

Sea campion can adjust to a wide range of temperatures, yet its distribution may still be restricted by particular combinations of moisture and heat. It grows best in warm summer climates with sufficient rainfall or irrigation. Extended periods of cloudy, rainy weather or prolonged high temperatures can raise the likelihood of Sea campion dying. In winter, adequate protection from cold can increase the plant's chances of survival.

Sea campion requires regular fertilizing to encourage flowering but does not tolerate excessive amounts. It benefits from light, frequent applications of fertilizer throughout its life, especially during the peak of active growth and while it is flowering. You should continue feeding your Sea campion until it stops blooming.
