Candytuft, or Iberis sempervirens, are known for their clusters of small, fragrant flowers that have a white bloom. Candytuft is often cultivated as a garden ornamental and is valued for its ability to form dense, attractive mounds of blooms. Here are some key features of candytuft:

Appearance: Candytuft plants are usually low-growing, forming neat, compact mounds of evergreen foliage. The flowers are small and can be found in dense clusters at the tips of the stems.

Flowering: Candytuft blooms heavily in the spring, and will sporadically bloom in the summer-early fall.

Colors: Candytuft flowers come in a range of colors, with white being the most common. 

Cultivation: These plants are relatively easy to grow and are often used in rock gardens, borders, or as ground cover. They prefer well-drained soil and full sun but can tolerate some partial shade.

Maintenance: Candytuft is generally low-maintenance, requiring occasional pruning to maintain a tidy appearance. Deadheading spent flowers can encourage further blooming.

Candytuft is a wonderful perennial groundcover that gives a magnificient show in the spring with a blanket of white blooms. Candytuft works well in many areas of the landscape and as a substitute for creeping phlox or ice plant.
