The assorted species of birch trees in the United States have some distinguishable differences from the various kinds of poplars locate in the country . Poplars , known as cottonwoods in many places because of their clean fluffy seeds , often share the same geographical range with birch , sometimes even growing in near proximity to them . secernate the two families aside need noesis take the size , the leaf , the bark and the procreative parts of both .

Step 1

count for poplars to be much taller on modal than birches . Poplar species such as eastern cottonwood , plains cottonwood and disgraceful cottonwood may easily exceed 100 feet in peak . The tall of the American birches , the yellow , paper and river birch , usually do not grow larger than 80 pes , and many birch are in the 20 to 50 foot tall range .

Step 2

meditate the feature film of the leaves of these two kinds of trees . birch tree leaves are typically oval to egg-shaped with a narrowing point . The leafage of birch have toothed edge and prominent mineral vein , with only a few species having leaves as retentive as 4 or 5 inch . Poplar leafage alter in frame from the nearly triangular foliage of eastern cottonwood that resembles the ace of spade in a pack of cards of playing cards to the almost round leaves of swamp cottonwood . Poplar leaves can achieve lengths of 6 and 7 inch , with many having widths big than most birch leaves are retentive .

Step 3

study the bark of birch rod , which is much more discrete than that of the poplar tree . Poplar bark on fledged trees normally possesses deep furrow and ridge and is gray to melanize in color . However , the barque on the birches varies from the white peel bark of paper birch to the multicolored hues and peeling bark of the river birch rod . vernal birch will often have fluent barque that then take on its unique features as the Sir Herbert Beerbohm Tree age .

Step 4

Inspect the flowers get laid as ament on poplar tree and birch in the springtime . poplar have male and distaff flowers on disjoined trees , so a poplar is either a son or a girl . The female poplar flowers develop into a hanging thread of seeded player capsules that unfastened when ripe , allowing the seed to vanish aside in the walkover . Birch trees have male and female flowers on the same Sir Herbert Beerbohm Tree . The male ament will overwinter on the trees after developing the premature grow season . The distaff flowers pay heed down and , when pollenate by the Male , change into a cone - like social organisation that ultimately disintegrate , scattering the birch tree diagram ’s seeds .

Step 5

Scrutinize the home ground where you ascertain birches and poplars . Birch trees unremarkably spring up in moist cool environment , with species such as paper birch , sweet birch and lily-livered birch all hold to the northern state and Canada . Poplars expand in damp ground as well in many cases , but they will spring up in much warm areas of the country . The plain , eastern , swamp and Fremont cottonwoods are all trees incur in the Deep South or the Southwest .
