Hosta Undulata Univittata will form a medium mound of about 14"-18" in height, with a spread of up to 24", at maturity. It is generally one of the first to emerge in spring. It has wavy leaves with curved tips and a very thin substance that makes them an attraction for slugs. It is interesting to see how the leaves on one hosta will not all look the same and will have many different markings. Undulata Univittata is listed as being sterile, but it does sometimes form seed pods, and the seeds are said to be viable. This low-growing selection has very wavy leaves, white in the centre, streaked with green and chartreuse. Pale lavender flowers appear very late in the season, on 30" scapes, in August. Not slug resistant and probably needs to be in dappled shade.
