Of the dozens of species
of willow there only a few are native to Alabama
and I’m familiar with just two or three of them.The easiest to identify is black willow, Salix nigra, because it has long narrow
alternate leaves that are green on the underside where many other willows have
leaves that are whitish on the underside and/or wider.Many of them also have larger and more
persistent stipules.Black willow is so
widespread that you can sometimes grow one just by putting a pot of native soil
in a tray of water. The Alabama champion black willow is 74 feet tall, has a girth of 144 inches, and an average limb spread of 66 feet. The second native
willow I saw in its native habitat was Carolina
willow, S. caroliniana, which is also
called coastal plain willow due to that being where the distribution range is
concentrated.It is similar to black
willow except for white underside on the leaves and a smaller mature size of
the tree.If I have seen any other in
our area is could be Missouri River willow, S. eriocephala, which has a disjunct
range in the Southeast.Assuming is has
significantly larger stipules I may have been mistaking it for coastal plain
willow.Silky willow, S. sericea, is
reported in northwest Alabama while Florida willow, S.
floridana, is possible in south Alabama
although it is listed as endangered in the only other states were it is found, Florida and Georgia.Of the willows outside our range pussy
willow, S. discolor, is probably the
most familiar (dirty jokes aside) because of the easily recognizable flower buds.I saw some willows and/or
poplars while at Philmont Scout Ranch, but there are so many possible kinds with
overlapping appearances that I have not been able to confidently identify them
to species besides keys sometimes being twigs that easily snap off such as in
the exotic crack willow, S. fragilis, which
is probably French.One of the most
recognizable willows is weeping willow, S. ×sepulcrali, which is synonymous with
S. babylonica where the namewas applied because the origin of samples
was mixed up thus this was believed to be the species of willow that the
Israelite captives hung their harps upon when taken to Babylon (Psalm 137), but it is more likely that the harps were actually hung on an aspen, Populus euphratica, since weeping willow is actually from China,
and it is a sterile hybrid of white willow, S.
alba, and another yet undetermined willow. Willow is used for numerous purposes including weaving
baskets, and Benjamin Franklin claimed to have introduced basket willow, S. vimimalis, to North America when he
salvaged sprouts from a discarded basket that had been shipped from Europe. Medicinally
willow was used to treat many ailments and most notably for pain relief, which
eventually resulted in aspirin.Another
important use is habitat restoration in riparian areas since most species
readily root in moist soil.
