As a companion plant, candytuft hides the less appealing lower growth of roses; or it can cascade from mixed planters.

Most roses that are grown for cut flowers are not very appealing in the landscape. They look better behind shorter perennials or shrubbery, with their taller flowering stems standing higher above. Mounding herbs like lavender, lavender cotton or rosemary, or small hedges of boxwood, dwarf hebe or Indian hawthorn obscurer their thorny undergrowth nicely. Candytuft, Iberis sempervirens, is a small perennial that gets just high enough to give a neat edge to a row of roses.

It gets gets about a foot deep, and can very slowly but eventually spread over a few square feet. The tiny, narrow and dark green leaves are less than an inch long. Inch wide trusses of minute white flowers resemble those of sweet alyssum, although lack fragrance. Sloppy plants can be restored by getting pruned almost to the ground.
