Plant Common Name

Emerald Tiara Plantain Lily, Hosta, Plantain Lily

General Description

Hostas need shade, right? Not always. The chartreuse-leaved ‘Emerald Tiara,’ like other hostas with yellow leaves, needs some sun to develop its glowing color. Hostas are herbaceous perennial grown for their leaves, mounding habit, toughness and tolerance of shade. This one has chartreuse to gold leaves with bright-green margins. They are heart-shaped, flat and ribbed. The flowers are purple-striped and funnel-shaped and appear on tall leafless stems held above the foliage in midsummer. The plants are medium-sized, form neat mounds and occasionally re-bloom.

Like most hostas, ‘Emerald Tiara’ grows best in full to partial shade and tolerates a wide range of well-drained soils. It needs at least some morning sun to maintain good leaf color. It needs average water and prefers even moisture. Use ‘Emerald Tiara’ for contrasts of color, texture and habit in shaded perennial gardens and woodlands, or massed as an herbaceous groundcover.
