< Back Maple (ACER NEGUNDO) - 'Sensation' ‘Sensation' was discovered by Warren Carnefix in Southwestern Idaho and it has a much improved branch structure and central leader than other varieties within the species. Spring foliage emerges brilliant in hues of copper red which fade to green with red highlights during the summer months then later turn soft, bright red in the fall. This unique and stunning tree is highly adaptable to site conditions including wet or dry soils and is extremely hardy. During it's youth, it forms a pyramidal shape and spreads as it ages. The trunk is silvery in tone and enhances the spectacular foliage beautifully. Furthermore, because it is a male seedless variety, it is considerably less attractive to boxelder bugs. Rising to a stature of 40 feet tall and roughly 30 feet wide, the 'Sensation Box Elder' Maple is nothing short of magnificent. Hardy to USDA Hardiness zone 3 and tough enough for dry, alkaline conditions, this makes an excellent specimen tree in the landscape, but looks handsome in group plantings as well. Plant this fast growing tree in full sun and water regularly. Once established, it only has moderate water requirements of 1/2" of water every 7-10 days. Pruning while young will help achieve the form you desire, but be sure to follow best pruning practices in order to promote health, provide air circulation, maintain a desirable shape, and to remove dead or damaged branches. Pruning is best done in late winter to early spring before the tree breaks dormancy. Protect the trunk especially while young to prevent damage from lawn mowing or other yard activities as well as winter burn. Previous Next

< Back Aspen, Quaking (POPULUS TREMULOIDES) As the breeze blows the leaves of the Quaking Aspen, the quaking of the flat-stemmed leaves create a rustling sound that is reminiscent of the mountain landscapes we love so much. This attractive tree robed in white, textured bark and small, glossy green leaves is highly adaptable to most soil conditions. It grows natively over a very large are of the northern United States and Canada. Suckering occurs as the tree gets older and if left unclipped can create a grove of Aspens. Fall color is beautiful golden yellow. Growing as high as 40 feet tall with a spread of 30 feet, Quaking Aspen is the most widely distributed tree in North America. It is known widely for it's ability to create a grove from it's suckering roots. If not desired, suckers should be pruned back. Rated at USDA Hardiness zone 2, this tree is an excellent choice in group plantings with evergreens and other deciduous trees and shrubs. Quaking Aspen will grow best in full sunlight and consistently moist well-drained soils, although it is quite adaptable. Grows best in cool, northern climates anywhere from rocky mountain tops to the clay soil in valleys in a wide range of elevations. Generally not tolerant of urban pollution. Aspens require careful monitoring as they are susceptible to a large number of disease problems, including dieback, leaf spots, rusts, powdery mildew and cankers. Diseased trees often suffer premature leaf drop as a result thereof. Common insect visitors include caterpillars, borers, aphids and scale. Treat accordingly. Previous Next

< Back Juniper Tree (JUNIPERUS SCOPULORUM) - 'MOONGLOW' Juniper 'Moonglow' is a very columnar tree with upright, bright, bluish green, needle-like foliage. Many landscapers enjoy it as an accent, combination, or screen planting thanks to it's neat and tidy upright growth. It has slightly blue cast, scale-like needles and the foliage serves as a pleasing contrast to other garden colors. It's branches ascend vertically contributing to the trees overall pyramidal shape. The bark of a 'Moonglow' Juniper is typically reddish brown, but can turn gray over time and exfoliates into thin strips which gives it somewhat of a shredded appearance. It is an easy specimen to grow. Standing at 20' tall and 5-8' wide, 'Moonglow' has a neat and tidy, columnar growth habit. As a cultivar of Rocky mountain juniper, it is cold hardy to USDA Hardiness Zone 3 and is very durable. Rocky Mountain Junipers are listed as a selection in the University of Wyoming "Conservation Trees & Shrubs For Wyoming" guide. This variety does best in cool climates and can tolerate a wide range of site and soil types, other than wet sites. It requires full sun for best blue color development and is extremely drought tolerant. Requires no pruning, but will handle it fine if it is clipped and, like most Junipers, is relatively free of insects and diseases. 'Moonglow' Junipers require very little water, but should be watered two to three times per week for the first month after being planted. Continue to monitor throughout the first year by using a trowel to uncover the first two or three inches of soil and checking moisture levels. Once established for a year, fertilize once in early spring (around April) and again in late summer (September) with a slow-release granular fertilizer with an NPK of 16-4-8 or 12-4-8. Junipers can be used in xeriscaping for water wise plantings. Previous Next

< Back Strawberry, Everbearing - 'Quinalt' Strawberry Nothing compares to the mouthwatering flavor of home-grown strawberries. 'Quinault' is a heavy producer of large, very sweet fruit. Use it in jams, preserves, tarts, and pies. Can be grown in ground, containers, and hydroponically. Hardy in USDA Zones 4A-8B with a height of 6-8 inches and a spread of 3 feet. Requires more than 6 hours of daily sun and light to medium moisture. Plant strawberries in early spring. Water them often through July. Remove flowers the first year and fertilize and water regularly. Do not plant them where tomatoes, peppers, potatoes, eggplant, or okra were planted the previous year. There is a disease that sometimes attacks these plants that will also attack strawberries. When planting, make sure that the roots are spread apart, and not tightly packed in a small hole. The plant will spread faster if the blossoms are removed so that more runners can be produced. The second year, allow the buds to stay so that fruit can be produced. Because strawberries have shallow roots, they should be fertilized during the growing season. Previous Next
