More Trees and Shrubs That Grow Well in Colorado |
By James Klett, Department of Horticulture, Colorado State University
Here are three more trees and three more shrubs that performed well in tests at the W.D. Holley Plant Environmental Research Center (PERC) gardens at Colorado State University.
Among recommended deciduous trees are:
Pyrus ussuriensis - Ussurian pear - This plant can be grown as a small to medium-sized tree or a large shrub. It flowers white in early spring, and its glossy, dark-green leaves turn yellow to orange in the fall. Once established, it tolerates cold temperatures, wind and dry growing conditions.
Sorbus aria - Whitebeam mountain ash - This overall smaller plant develops an open, rounded growth habit. It blooms white cluster flowers, followed by orange-red fruit. Its simple, lobed dark-green leaves feature white hairs on their undersides.
Syringa pekinensis - Pekin lilac - This upright arching loose tree with a more open growth habit blooms yellowish white flowers. It has brown exfoliating bark. Pekin lilac can be grown as a large shrub or small tree.
Among recommended deciduous shrubs are:
Berberis koreanna - Korean barberry - This plant with a multi-stemmed growth habit is a clump former. Its yellow flowers are followed by red berry fruit. This adaptable plant makes a good barrier plant.
Lonicera x xylosteiodes `Miniglobe' Miniglobe honeysuckle - Introduced by the Morden Research Station , it has slow growth and dense, rounded form. When mature, its leaves feature a bluish tinge. The plant prefers moist, sunny conditions in a well-drained site.
Prinsepia sinesis - Cherry prinsepia - This is one of the season's first shrubs to leaf out. Its light-yellow flowers are highly fragrant. Its dark green foliage and small spines make it an effective barrier plant. This plant has a dense growth habit and appears to have no major problems.
