Hosta Vulcan forms an eye-catching mound, of 18"-22" in height and 32"-36" in width at maturity. It has broad, heart-shaped leaves with pure white centres, dark green margins and pale yellow streaks jetting in between. Star-like lavender flowers appear in mid to late summer, rising on tall (24") white scapes. Vigorous, once established, slow to start, it is ideal for dappled shade. Hosta 'Vulcan' is a sport from 'Captain Kirk' and much like its parent, is a strong grower once established. Golden-yellow streaks occur along the interior margins where the white and green overlap. Excellent growth rate for a white-centered hosta. This hosta will shine in any garden. This is slug resistant and sun tolerant.
