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.
A lovely big bushy plant that gives a billowing sense of informality to the very late flowering border. Ideal with the big Eupatorium or Miscanthus, or perhaps some autumn foliage shrubs.
As with most of the autumn flowering asters 'Novemberblau' can be "Chelsea-chopped" in late May or June to reduce the height and increease the number of flowering stems. This will have the effect of keeping the flower stems more upright and delaying flowering a couple of weeks.
Formerly Aster laevis 'Novemberblau'.
Symphyotrichum foliaceum coll. Montana£8.50
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.
Symphyotrichum laeve 'Glow in the Dark'£7.50
An outstanding recent introduction with purple flushed deep green leaves and heads of light pink flowers in autumn to 1.5m. Reasonably self-supporting!
Symphyotrichum laeve 'Nightshade'£4.50
Amazing glowing lavender blue flowers on dark stems clothed with deep green leaves in autumn. Strong upright habit to 1.4m. Good soil in sun.
