Ornamental Features

Heavenly Habit Jacob's Ladder has masses of beautiful spikes of lightly-scented lilac purple star-shaped flowers with white eyes and yellow anthers rising above the foliage from mid spring to mid summer, which are most effective when planted in groupings. The flowers are excellent for cutting. Its ferny pinnately compound leaves remain dark green in color throughout the season. The fruit is not ornamentally significant.

Landscape Attributes

Heavenly Habit Jacob's Ladder is an herbaceous perennial with tall flower stalks held atop a low mound of foliage. It brings an extremely fine and delicate texture to the garden composition and should be used to full effect.

This is a relatively low maintenance plant, and is best cleaned up in early spring before it resumes active growth for the season. Deer don't particularly care for this plant and will usually leave it alone in favor of tastier treats. It has no significant negative characteristics.

Heavenly Habit Jacob's Ladder is recommended for the following landscape applications;

  • Mass Planting
  • Rock/Alpine Gardens
  • Border Edging
  • General Garden Use
  • Container Planting

Planting & Growing

Heavenly Habit Jacob's Ladder will grow to be about 10 inches tall at maturity extending to 15 inches tall with the flowers, with a spread of 12 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 10 inches apart. Its foliage tends to remain low and dense right to the ground. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 10 years.

This plant does best in full sun to partial shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This is a selected variety of a species not originally from North America. It can be propagated by division; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.

Heavenly Habit Jacob's Ladder is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. 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.
