Many plants go dormant during the winter, but the Sea Squill does the opposite! When temperatures start to rise and water becomes less available, this plant sheds its leaves and conserves energy until conditions become more favorable.

During its flowering cycle, the Sea Squill attracts insect pollinators like bees and butterflies, giving it an important role in the pollination cycle!
