Birch tree , of the genus Betula , are quite different than aspen tree diagram , of the genus Populus . Both trees have the potentiality of growing to around the same height , and both share brilliant fall foliage . The color of the fall leaves and the general stature of these trees is where the law of similarity end , as there are many conflict between birch trees and aspen tree diagram .
Bark Appearance
Birch tree bark is marked with horizontal lenticel , or cellular bunch that act as pores on the tree . The color of the bark may be hoar , grey white , grayish flushed or grayish black . Because of the marking due to the lenticel , the papery barque of birch tree easily flakes and peels off of the body of the tree . The bark of aspen tree is liquid and bloodless , pock only from time to time by unadulterated black mi or scarring .
Leaf Appearance
Regardless of the species of birch , the leave of absence appear the same . birch rod leaves are alternate in their organization on the twig . They are doubly notched , meaning the sharpness of the leaves resemble the blade of a saw , with larger " sawing machine teeth " intersperse among humble ones . Birch leaves have a okay internet veins scarper through them , halt from a single , fundamental vein . Birch leaves have leaf stems , foretell petioles , with a rounded stipule , or bump where the leaf attaches to the twig .
Aspen leaf are almost perfectly round . While not serrate , the leaf margins of aspen leave of absence are marked by rounded dentition , resemble tiny bump along the border . The petioles of aspen leave-taking are matted and alternately arranged along the branchlet .
Buds
Before leaves ever appear , they begin as bud on the end of branches . During the winter , scar where these buds exist in premature geezerhood can give a cue to the identification of a Sir Herbert Beerbohm Tree without any leaves present .
Birch tree buds form in the early spring and are to the full produce by the start to eye of summer . bud are arranged laterally on the tree , and branches do not have final buds . The bud are ruby - purpleness in color and shape like cones .
Aspen buds are scarlet - brown in colouring . Aspen tree buds are conic , like those of a birch rod tree diagram , differing in that aspen Tree form terminal buds . Aspen bud normally make later in the time of year than birch tree buds , requiring less time to grow . The bud scar are more spectacular against the white bark of the tree .
Climate and Location
Aspen trees are restricted to USDA insensate hardiness zone 1 through 6 , with tree diagram in warmer and considerably cold climates becoming dwarf . Birch tree generally acquire best in USDA cold hardiness zones 6 through 3 , but can stomach warmer and cold climates with only a small difficulty . Aspen tree are found across the North American continent from Canada down to Mexico , while birch rod trees are generally only establish in the easterly United States and part of Canada .
Growth Requirements
Birch trees thrive in partial sunlight , while aspen trees require full Lord’s Day . Birch trees require slackly packed grease to accommodate their shallow tooth root systems , while aspen tree bear a diverseness of soil conditions .
