General Description

This is a tried and true large blue hosta. Krossa regal plantain lily is a clump forming, shade tolerant, herbaceous perennial that is primarily grown for its ornamental foliage. In spring, it produces a large clump of lance-shaped, waxy leaves of blue-green. In midsummer, upright, sturdy stems of bell-shaped, pale lavender flowers appear. This hosta prefers part sun to part shade and fertile, well drained soil. It is widely used in mixed perennial borders and massed as a large groundcover for shade. Most hosta are highly susceptible to slug damage.
