Family: Berberidacaea

Common name: yellow barrenwort; yellow bishop’s hat
Zone: 5 – 9
Height: 12-15 in (30-38cm)   Spread: 12 in (30cm)
Aspect: partial shade; full shade
Soil: fertile; humus-rich; well-draining

Description: An evergreen perennial with a mounding, slow spreading habit. Pale yellow, bishop hat-shaped flowers appear at the top of spurs in mid- through late spring. Heart-shaped, dark green leaflets are flushed a deep bronze-red colour when they first appear during the flowering period, gradually losing this flush as the season progresses. Leaves form a very pleasing evergreen mound.

 

Special Notes: Hybrid seedling of E. grandiflorum x E. pinnatum subsp. cochicum. This plant is valued for its ability to thrive and prosper amongst the tough roots of mature trees. Needs fertile soil and regular watering during the hot summer periods when planted in full sun. Flower production will not be as vigorous and winter foliage colour will be compromised if planted in full shade. Cut leaves back in early February to view the flowers and allow for fresh new growth. Fresh plant divisions will take up to two years to establish. Propagate by division in autumn.
