Burr Oak can grow to 15 to 30 metres tall. It tolerates a wide variety of moisture conditions; it prefers full sun, but can tolerate moderate shade; and it can grow in a variety of soils.
In addition to its notable strength, Burr Oak has other attributes that make it a splendid tree for urban landscapes. It provides food for squirrels, dense shade, and is resistant to air pollution and heat stress. Its generally slow growth is compensated by longevity.
Wild raisin prefers moist, shady sites, but can grow in almost any condition. It is one of our most shade and flood tolerant shrubs.
Unlike some other shrubs, wild raisin consistently bears heavy crops of fruit. Berries are a not a preferred food, but are eaten by many birds. Small animals all make use of the fruit, which can hang on late into the winter. Especially where it forms dense thickets, wild raisin provides valuable cover for many types of mammals and birds.
It has pretty white blossoms that adorn the plant in the late spring and are followed by large clusters of bright red edible berries by the end of summer. Later, the foliage puts on a show with plenty of fall colour.
The tree's trunk is covered in thin, smooth white bark that peels off in large sheets. Bark from the white birch is very strong and pliable — it can be used to make canoes. Buds, leaves and seeds from the white birch are a great source of food for birds and animals.
This tough, low-maintenance shrub offers subtle year-round beauty. White panicles of flowers brighten the landscape in June. White berries attract many birds in the late summer and early fall. And the reddish-pink fruit stems persist into the winter, adding a nice color contrast to the gray bark.
Non-fragrant white flowers in flat-topped cymes (to 4.5" diameter) appear in spring. Flowers give way in autumn to blue-black, berry-like drupes which often persist into winter and are quite attractive to birds and wildlife. Fruits are edible and may be eaten off the bush when ripe or used in jams and jellies.
