The name comes from the latin word "clausa", meaning "closed". It describes the plant's flowers that do not open.
Description
editHosta clausa is known for its vibrant purple flower buds. It has a rhizomatous growth habit.
The foliage consists of lance-shaped leaves that are about one inch wide. They're deep green in colour with a glossy surface and a sharply pointed tip. The flower scapes, or stalks, bear numerous dark purple buds and exhibit purple dots near their base.
As a triploid hosta, this variety does not produce seeds. However, its pollen remains fertile, allowing it to participate in cross-pollination with other hosta species.
