Iberis sempervirens

Iberis sempervirens, commonly known as Candytuft, is a low-growing, spreading evergreen perennial. It forms a dense mat of dark green, linear leaves and produces masses of small, white flowers in spring, creating a snow-like effect. While primarily an outdoor plant valued for its ground cover and spring blooms in rock gardens and borders, it is not ideally suited for indoor cultivation due to its high light requirements and need for cooler temperatures to thrive. People grow it for its early spring blooms and drought tolerance.
