Warm orange-peach flowers that bloom all summer long; refreshing licorice scented foliage; an improved, dense mounded habit; tubular flowers attract pollinators to the garden
Summer Sunset Hyssop features airy spikes of lightly-scented orange tubular flowers with peach overtones rising above the foliage from late spring to late summer. 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.
Summer Sunset Hyssop is a dense 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.
Summer Sunset Hyssop is recommended for the following landscape applications;
Planting & Growing
Summer Sunset Hyssop will grow to be about 14 inches tall at maturity, 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.
Summer Sunset Hyssop 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 and foliage 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.
