Profusion of lavender-blue flowers that mature to white, and attractive lance-like green leaves; prefers cool, moist soil; water the root zone instead of from the top to reduce fungal disease; water regularly to encourgage more blooms
Wartburg Star Aster has masses of beautiful lavender daisy flowers with yellow eyes at the ends of the stems from late spring to early fall, which are most effective when planted in groupings. The flowers are excellent for cutting. Its narrow leaves remain green in color throughout the season. The fruit is not ornamentally significant.
Wartburg Star Aster 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 butterflies 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.
Wartburg Star Aster is recommended for the following landscape applications;
- Mass Planting
- Rock/Alpine Gardens
- Border Edging
- General Garden Use
- Container Planting
Planting & Growing
Wartburg Star Aster will grow to be about 18 inches tall at maturity extending to 24 inches tall with the flowers, with a spread of 15 inches. Its foliage tends to remain dense right to the ground, not requiring facer plants in front. 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 prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. 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.
Wartburg Star Aster 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.
