Product Description
Tall, dark and handsome! Hollyhock ‘Blacknight’ is a classic variety, universally admired for its sultry, near-black flowers with pale yellow eyes. The large, single, saucer-shaped flowers with silky petals glisten in the sunshine, brooding over borders on sturdy stems that can reach up to 2 metres. This magnificent hollyhock always attracts admiring glances, adding dark mystery and romance to the garden. It is also a magnet for pollinators. Ultimate height: 2m (6.5ft) Ultimate spread: 60cm (24in).Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.
