Aster 'Fran's Gift'
Sorry but this is not this asters correct name, it was a gift many years ago by Fran in Dunedin. I feel it is a cordifolius hybrid and could be 'Elegans' which was being grown in gardens pre 1920. The flowers are white with a slight hint of lavender. A strong grower up to 1.2m. Makes good clumps.
