Memorial Tree Selections
"All trees are unique in their design, bark, texture and colors. The trees we've selected are unique to the Arboretum and would be a beautiful compliment to the current species and most unique to Montana".
Picea engelmannii, with common names Engelmann spruce, white spruce, mountain spruce, or silver spruce, is a species of spruce native to western North America, from central British Columbia and southwest Alberta, southwest to northern California and southeast to Arizona and New Mexico; there are also two isolated populations in northern Mexico. It is mostly a high altitude mountain tree, growing at 900 metres (3,000 ft) – 3,650 metres (11,980 ft) altitude, rarely lower in the northwest of the range; in many areas it reaches the alpine tree line. The Engelmann Spruce is native to both Yellowstone Park and the Big Horn Mountains of northern Wyoming.
Pinus albicaulis, known by the common names whitebark pine, white pine, pitch pine, scrub pine, and creeping pine, is a conifer tree native to the mountains of the western United States and Canada, specifically subalpine areas of the Sierra Nevada, Cascade Range, Pacific Coast Ranges, and Rocky Mountains from Wyoming northwards.
The whitebark pine is typically the highest-elevation pine tree found in these mountain ranges and often marks the tree line. Thus, it is often found as krummholz, trees growing close to the ground that have been dwarfed by exposure. In more favorable conditions, the trees may grow to 95 ft in height.
The type species, Cercidiphyllum japonicum, can reach 148 ft in height, and is one of the largest hardwoods in Asia. The other species, Cercidiphyllum magnificum, is much smaller, rarely reaching over 33 ft in height. Cercidiphyllum produces spurs along its twigs. These are short stems with closely spaced leaves. The foliage is dimorphic. According to a recent description "short shoots bear broadly cordate or reniform, palmately veined leaves with crenate margins; long shoots bear elliptic to broadly ovate leaves with entire or finely serrate margins. Leaf size varies from 3–8 cm long and 3-5.5 cm broad. The genus is dioecious, having separate male and female trees. The small inconspicuous flowers are produced in early spring.
London Plane Tree
The London plane is a large deciduous tree growing 66–98 ft, exceptionally over 131 ft tall, with a trunk up to 10 ft or more in circumference. The bark is usually pale grey-green, smooth and exfoliating, or buff-brown and not exfoliating. The leaves are thick and stiff-textured, broad, palmately lobed, superficially maple-like, the leaf blade 4–8 in long and 5–10 in broad, with a petiole 1–4 in long. The young leaves in spring are coated with minute, fine, stiff hairs at first, but these wear off and by late summer the leaves are hairless or nearly so. The flowers are borne in one to three (most often two) dense spherical inflorescences on a pendulous stem, with male and female flowers on separate stems. The fruit matures in about 6 months and comprises a dense spherical cluster of achenes with numerous stiff hairs which aid wind dispersal; the cluster breaks up slowly over the winter to release the numerous seeds. The London Plane is one of the most efficient trees in removing small particulate pollutants in urban areas.
The eastern redbud typically grows to 20–30 ft tall with an 26–33 ft spread. It generally has a short, often twisted trunk and spreading branches. A 10-year-old tree will generally be around 16 ft tall. The bark is dark in color, smooth, later scaly with ridges somewhat apparent, sometimes with maroon patches. The twigs are slender and zigzag, nearly black in color, spotted with lighter lenticels. The winter buds are tiny, rounded and dark red to chestnut in color. The leaves are alternate, simple, and heart shaped with an entire margin, 3–4.5 in long and wide, thin and papery, and may be slightly hairy below.
The flowers are showy, light to dark magenta pink in color, 1⁄2 in long, appearing in clusters from Spring to early Summer, on bare stems before the leaves, sometimes on the trunk itself.
The cherry plum is a popular ornamental tree for garden and landscaping use, grown for its very early flowering. Numerous cultivars have been developed, many of them selected for purple foliage, such as P cerasifera var pissardii .The variety 'Nigra' with black foliage and pink flowers, has gained the Royal Horticultural Society's Award of Garden Merit, Prunus × cistena (purple leaf sand cherry found in the Asian Garden) a hybrid of Prunus cerasifera and Prunus pumila, the sand cherry, also won the Award of Garden Merit. These purple-foliage forms (often called 'purple-leaf plum'), also have dark purple fruit, which make an attractive, intensely coloured jam. They can have white or pink flowers. The cultivar 'Thundercloud' has bright red foliage which darkens purple.Others, such as 'Lindsayae', have green foliage. Some kinds of purple-leaf plums are used for bonsaiand other forms of living sculpture.
Abies grandis (grand fir, giant fir, lowland white fir, great silver fir, western white fir, Vancouver fir, or Oregon fir) is a fir native to the Pacific Northwest and Northern California of North America, occurring at altitudes of sea level to 5900 feet. It is a major constituent of the Grand Fir/Douglas Fir Ecoregion of the Cascade Range.
The tree typically grows to 130-230 feet in height. There are two varieties, the taller coast grand fir, found west of the Cascade Mountains, and the shorter interior grand fir, found east of the Cascades. It was first described in 1831 by David Douglas.
It is closely related to white fir. The bark has historical medicinal properties, and it is popular in the United States as a Christmas tree. Its lumber is a softwood, and it is harvested as a hem fir. It is used in paper-making, as well as construction for framing and flooring, where it is desired for its resistance to splitting and splintering.
Picea glauca, the white spruce,is a species of spruce native to the northern temperate and boreal forests in North America. Picea glauca was originally native from central Alaska all through the east, across southern/central Canada to the Avalon Peninsula in Newfoundland. It now has become naturalized southward into the far northern United States border states like Montana, Minnesota, Wisconsin, Michigan, Vermont, New Hampshire and Maine; there is also an isolated population in the Black Hills of South Dakota and Wyoming. It is also known as Canadian spruce, skunk spruce, cat spruce, western white spruce, Alberta white spruce, and Porsild spruce. Sometimes known as Black Hills Spruce. The Black Hills Spruce species can be found throughout the Arboretum such as the Eagle Habitat and Millennium Grove and does differ somewhat from the White Spruce. It is a very hardy tree for our Montana climate.
