Bees and butterflies just cannot resist the nectar rich deep violet blue blooms of 'Blue Boa'. They flock to its dense flower spikes that appear from mid summer deep into autumn, only to be stopped by the first frosts. Its green dagger-shaped foliage is deliciously mint-scented too.
An elegant addition to a late season garden, it remains upright over winter providing further interest especially when kissed by a hoar frost. Naturally preferring a poor, well-drained soil baked in full sun, it makes a great candidate for a sunny container, wildlife or gravel garden and is great for cutting and drying. Irresistable.
