Clumps of deep green foliage and upright stems topped with heads of lavender-blue flowers in late summer. 50cm. Best in good soil in full sun, ideal with grasses like Panicum.
An outstanding recent introduction with purple flushed deep green leaves and heads of light pink flowers in autumn to 1.5m. Reasonably self-supporting!
Just about the last "aster" to flower here well into November. Masses of relatively large lavender blue flowers on branched stems up to 1.5m. Average soil in sun.
