Ornamental Features

Purple Haze Hyssop features airy spikes of lightly-scented purple tubular flowers with lilac purple overtones and fuchsia calyces rising above the foliage from mid summer to early fall, which emerge from distinctive hot pink flower buds. The flowers are excellent for cutting. Its attractive fragrant narrow leaves remain grayish green in color throughout the season. The fruit is not ornamentally significant.

Landscape Attributes

Purple Haze Hyssop is an open herbaceous perennial with an upright spreading habit of growth. Its relatively fine texture sets it apart from other garden plants with less refined foliage.

This is a relatively low maintenance plant, and is best cleaned up in early spring before it resumes active growth for the season. It is a good choice for attracting bees, butterflies and hummingbirds to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Purple Haze Hyssop is recommended for the following landscape applications;

  • Mass Planting
  • General Garden Use
  • Naturalizing And Woodland Gardens
  • Herb Gardens
  • Container Planting

Planting & Growing

Purple Haze Hyssop will grow to be about 24 inches tall at maturity extending to 3 feet tall with the flowers, with a spread of 24 inches. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 6 years.

This plant should only be grown in full sunlight. 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. It is not particular as to soil type, but has a definite preference for alkaline soils, and is able to handle environmental salt. It is somewhat tolerant of urban pollution. This particular variety is an interspecific hybrid. 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.

Purple Haze Hyssop is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
