Ornamental Features

Anise Hyssop has masses of beautiful spikes of lightly-scented lavender flowers rising above the foliage from mid summer to mid fall, which are most effective when planted in groupings. The flowers are excellent for cutting. Its attractive fragrant pointy leaves remain dark green in color throughout the season.

Landscape Attributes

Anise Hyssop is an herbaceous perennial with an upright spreading habit of growth. Its medium texture blends into the garden, but can always be balanced by a couple of finer or coarser plants for an effective composition.

Planting & Growing

Anise Hyssop will grow to be about 32 inches tall at maturity, with a spread of 32 inches. It tends to be leggy, with a typical clearance of 1 foot from the ground, and should be underplanted with lower-growing perennials. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 6 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!

This plant performs well in both full sun and full shade. It is very adaptable to both dry and moist growing conditions, but will not tolerate any 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. It is somewhat tolerant of urban pollution. This species is native to parts of North America. It can be propagated by division.

Anise 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. It is even sizeable enough that it can be grown alone in a suitable container. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
