Evergreen trees are popularly used in landscapes to keep colour and texture in the gardens all through the year even when most other plants go dormant. Miniature or dwarf evergreens are smaller versions of the larger trees and are well suited for smaller areas and for containers to place on patios, decks, entryways and balconies. Evergreens adapt to areas of sun and partial shade and perform well with mulch and additional watering during warm, windy or dry weather conditions.
Alberta blue (Picea glauca 'Haal') is a miniature version of the larger Alberta spruce, growing to a mature height of 5 to 7 feet with a 2-foot spread. The cold-tolerant tree has silver-blue, evergreen foliage and develops into a compact and narrow conical mature shape. Alberta blue is hardy in USDA plant hardiness zones 2 to 8 and prefers to grow in areas of sun to partial shade. The deer-resistant tree is a native of North America and is among the evergreens well adapted to growing in wet soil. The dwarf stature of the tree makes it an ideal choice for use in rock gardens and as a container plant. Water established trees occasionally.
Dwarf Blue Subalpine Fir
Dwarf blue subalpine fir (Abies lasiocarpa 'Glauca Compacta') is a soft evergreen conifer with blue needles and a miniature height of 6 to 8 feet. The dense growing tree has a pyramidal mature shape and grows slowly. The North American native tree is low maintenance with regular watering requirement, often weekly during very hot weather. Dwarf blue subalpine fir does not produce any flowers and is well suited for growing as a container plant. Grow the tree in areas of full sun for optimal growth. Dwarf blue subalpine fir is hardy in zones 3 to 7.
Feelin' Blue Deodar Cedar
'Feelin' Blue' deodar cedar (Cedrus deodara 'Feelin' Blue') is cited as the lowest growing dwarf evergreen by the Monrovia horticultural website with its full height of 2 feet. The evergreen conifer has blue-green needles and is hardy in zones 7 to 9, growing best in areas of full sun. 'Feelin' Blue' has a compact growth and is well tolerant of coastal air. The small tree does not produce any flowers and is among the plants used for erosion control. Established 'Feelin' Blue' trees have a minimal watering requirement and are ideal for use in small sized gardens.
