Impatiens omeiana – A hard to find perennial Impatiens which is native to China and makes a great filler plant between deciduous trees and shrubs. It is primarily grown as a foliage plant with dark green leaves and prominent creamy-yellow midribs and veining that forms a dense cluster. Pale yellow flowers are borne late summer. Grows 15″ high by 2-3′ wide. Hardy to zone 6.
Viola sororia ‘Freckles’ – An easy to grow perennial violet with unique white flowers heavily spotted in porcelain blue from April to June. They grow well in part to full shade and the edible flowers make a nice salad garnish (if grown organically). The heart-shaped apple green foliage forms a dense cluster. Somewhat prone to self-seeding. Grows 6-8″ high by 8-12″+ wide. Hardy to zone 4.
Hosta ‘Moonstruck’ – This reverse variegation sport of ‘Dress Blues’ features slender leaves of dark greenish-blue margins (with some lime highlights) and creamy-white to pale yellow centers. It is a reasonably fast grower and bears pale lavender flowers on 18″ high scapes in early summer. This smaller Hosta works well in containers. Grows 12″ high by 18″ wide. Hardy to zone 3.
Impatiens omeiana ‘Silver Pink’ – This cultivar of the hardy Impatiens truly adds some colour to our often boring green shade gardens. It features deep bronze-green leaves with dark pink midribs and veining, reddish stems and occasional silver highlights. Pale yellow and white flowers are borne in small terminal clusters late summer to fall. Grows 6″ high by 12″+ wide. Zone 7.
Disporum sessile ‘Variegatum’ – A truly striking foliage plant, this variegated Fairy Bells looks like a small Solomon’s Seal with medium green tapered foliage that is generously striped and edged in white. Pendulous bell-shaped pale green flowers that mature to to white are produced in April, followed by purplish-black berries. Prefers evenly moist well-drained soils. 12-16″ high by 2-3′. Z4.
