Symphyotrichum novi-belgii 'Tonga'

Asters are in the daisy family and while some flower in spring, most flower in late summer and autumn, hence their common name Michaelmas daisy. They provide a welcome splash of colour when other flowers are starting to fade, and are an important source of nectar and pollen for late-flying insects.

Symphyotrichum novi-belgii TONGA ('Dasthree') ('Island Series') is a compact aster, bearing bright purple flowers with a bright yellow centre. It's ideal for growing at the front of herbaceous borders, and is perfect for growing in pots as part of an autumn container display. For best results plant Symphyotrichum novi-belgii 'Tonga' in well-drained soil in a sheltered, sunny site. Cut plants back hard after flowering.
