Verbena hastata 'White Spires'
An upright perennial producing tall stems topped with candelabra-like short spires of many tiny pure white flowers. Creates a dreamy vertical accent in the garden and pairs well with almost anything. Flowers for a long time over summer, and useful as a cut flower as well. Trim after flowering or allow a few seed heads to ripen if you want self-sown seedlings. Flowering size 70-120cm high x 30cm wide. 9cm pot.
