Brilliant but delicate deep mauve-pink flowers are borne above the beautiful green foliage in the warm summer months; though less hardy to temperature it is resilient to most other atmospheric effects including pollution and seasalts
Heatwave Sparkle Autumn Sage has masses of beautiful racemes of fragrant hot pink flowers with white eyes rising above the foliage from early summer to mid fall, which emerge from distinctive burgundy flower buds, and which are most effective when planted in groupings. The flowers are excellent for cutting. Its fragrant narrow leaves remain green in color throughout the year. The fruit is not ornamentally significant.
Heatwave Sparkle Autumn Sage is an herbaceous evergreen 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.
This is a relatively low maintenance plant, 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, 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.
Heatwave Sparkle Autumn Sage is recommended for the following landscape applications;
- Mass Planting
- Border Edging
- General Garden Use
- Container Planting
Planting & Growing
Heatwave Sparkle Autumn Sage will grow to be about 14 inches tall at maturity extending to 24 inches tall with the flowers, with a spread of 18 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 14 inches apart. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 5 years.
This plant does best in full sun to partial 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 pH, but grows best in rich soils, and is able to handle environmental salt. It is somewhat tolerant of urban pollution. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. 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.
Heatwave Sparkle Autumn Sage 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.
