Abstract
A new and distinct Hosta plant named ‘Sound of Music’ producing very large-sized rounded mounds of basal, broadly-cordate to rounded, giant-sized leaves with acute apices, cordate bases, slightly wavy margins and a tendency to cup downwardly toward the apex. The leaves are variegated having glaucous bluish-green margins and centers that begin the season chartreuse and become creamy-yellow as the season progresses with intermediate color separation between the margin and center of variably large segments of several shades of chartreuse. The campanulate flowers are near pale purple just above the foliage beginning in mid to late June. ‘Sound of Music’ is useful in the landscape, as a container plant, a specimen or en masse.
