Hosta Sister Act will develop into a medium-sized mound reaching 40cm-55cm in height, with a spread of up to 115cm upon maturity. It features thick, puckered leaves that are yellowish green with a broad green border. This sport of Hosta Step Sister exhibits the same growth habit and performance as its parent but with significantly wider green margins. It demonstrates good vigour and garden performance. In spring, the leaves of Hosta Sister Act emerge coated in wax, giving the gold centre a hazy appearance and turning the margins blue. During summer, the leaves transition to bright gold, and the margins become dark green, creating a striking colour contrast in the garden. Near-white flowers bloom on 95cm scapes from July to August. This Hosta is resistant to slugs and tolerant of sun exposure.
