Description:

A sprawling, multi-stemmed plant with fleshy, narrow, bluish-green leaves; tiny white flowers with yellow-green throats emerge from gradually uncoiling stalks from spring to fall, and turn violet as they age; great for rock gardens and coastal areas

Ornamental Features

Salt Heliotrope features unusual chains of white star-shaped flowers with chartreuse eyes at the ends of the stems from mid spring to mid fall. Its small narrow leaves remain bluish-green in colour with hints of gray throughout the season.

Landscape Attributes

Salt Heliotrope is an herbaceous annual with an upright spreading habit of growth. It brings an extremely fine and delicate texture to the garden composition and should be used to full effect.

This plant will require occasional maintenance and upkeep, and should only be pruned after flowering to avoid removing any of the current season's flowers. It is a good choice for attracting bees and butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;

  • Spreading
  • Self-Seeding

Salt Heliotrope is recommended for the following landscape applications;

  • Mass Planting
  • Rock/Alpine Gardens
  • Groundcover
  • Naturalizing And Woodland Gardens
  • Container Planting
  • Hanging Baskets

Planting & Growing

Salt Heliotrope will grow to be about 18 inches tall at maturity, with a spread of 3 feet. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 24 inches apart. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. Although it's not a true annual, this fast-growing plant can be expected to behave as an annual in our climate if left outdoors over the winter, usually needing replacement the following year. As such, gardeners should take into consideration that it will perform differently than it would in its native habitat.

This plant does best in full sun to partial shade. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. This plant does not require much in the way of fertilizing once established. It is not particular as to soil pH, but grows best in sandy soils, and is able to handle environmental salt. It is somewhat tolerant of urban pollution. This species is native to parts of North America, and parts of it are known to be toxic to humans and animals, so care should be exercised in planting it around children and pets. It can be propagated by division.

Salt Heliotrope is a fine choice for the garden, but it is also a good selection for planting in outdoor containers and hanging baskets. It is often used as a 'filler' in the 'spiller-thriller-filler' container combination, providing a mass of flowers against which the larger thriller plants stand out. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
