‘Blue Boa’ is a new introduction with spikes of deep violet blue flowers held over deep green, aromatic foliage with a distinct licorice flavour. Reaching 45-60cm in height, longflowering ‘Blue Boa’ blooms from early summer right through until the frosts end the display. Drought tolerant once established and attractive to bees and butterflies.
This looks to be an improvement on the similar Award of Garden Merit winning ‘Blue Fortune’. Dependably hardy, unlike ‘Blue Fortune’, the flowers of ‘Blue Boa’ are deeper in colour, and the long flower spikes are also fatter than those of ‘Blue Fortune’.
