Island Tonga Aster has masses of beautiful purple daisy flowers with yellow eyes at the ends of the stems, which are most effective when planted in groupings. Its narrow leaves remain dark green in colour throughout the season.
Island Tonga Aster is a dense herbaceous perennial with a ground-hugging 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. Gardeners should be aware of the following characteristic(s) that may warrant special consideration:
Island Tonga Aster is recommended for the following landscape applications:
Planting & Growing
Island Tonga Aster will grow to be about 12 inches tall at maturity, with a spread of 12 inches. Its foliage tends to remain low and dense right to the ground. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 4 years.
This plant does best in full sun to partial shade. It prefers to grow in average to dry locations, and dislikes excessive moisture. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. 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.
Island Tonga Aster is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. Because of its spreading habit of growth, it is ideally suited for use as a 'spiller' in the 'spiller-thriller-filler' container combination; plant it near the edges where it can spill gracefully over the pot. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, most plants cannot be expected to survive the winter if left in containers outdoors, and this plant is no exception.
