Hosta Smoke Signals will form a medium-sized mound reaching 45cm-55cm in height and spreading up to 105cm at maturity. This variety features heavy, spear-shaped leaves that are smooth, gently folded, and slightly wavy around the edges. The intense blue colour of the leaves remains vibrant well into late summer. The Hosta exhibits a durable, upright symmetrical growth habit and produces near-white, fertile flowers with light lavender stripes on 70cm blue scapes during mid-summer. Its thick leaves make this one resistant to slugs.
