Hosta Sister Act will form a medium sized mound of 16"-22" in height, with a spread of up to 46", at maturity.  It has thick and puckered, yellowish-green leaves with a wide green border.
This sport of 'Step Sister' has the same habit and performance as the parent but with very wide green margins. Good vigour and garden performance. Leaves on 'Sister Act' emerge with a wax coating in spring which gives the gold center a hazy appearance and the makes the margins blue. In summer the leaves turn bright gold and the margins become dark green. The colour contrast in summer really stands out in the garden. Near white flowers appear on 38" scapes, July to August. Slug resistant & sun tolerant.
