Flowers in the mustard family (Brassicaceae, formerly Cruciferae) are most notably distinguished by their cross-like structure.  This distinct appearance led to the traditional name crucifers, referring to the four petals arranged in the shape of a Greek cross.  The mustard family also possess and highly distinctive pungent, peppery or sulfurous aroma when the tissues are crushed.

Iberis, commonly known as candytuft, is one example. Native primarily to the Mediterranean region, these plants are prized for their dense clusters of small, four-petaled flowers that typically bloom in shades of white, pink, or purple. The flowers have a sweet, honey-like fragrance. The plant has Mediterranean origins, thought to be in the area of Crete. Iberis species range from annuals to evergreen perennials, with popular varieties like Iberis sempervirens often used in ornamental gardening.

Gardeners value Iberis for its ability to form low, spreading mounds that work well as ground cover, edging plants, or additions to rock gardens. They thrive in well-drained soil and full sun, and once established, many varieties are relatively drought-tolerant. Beyond their aesthetic appeal, candytuft flowers can attract pollinators such as bees and butterflies, contributing to garden biodiversity. Their long-lasting blooms and neat growth habit make them a dependable choice for both formal and informal landscape designs.
