Physical Description:
Growth Habit:
Black tupelo is a large shade tree. It prefers evenly moist, deep
acidic soils in full sun, but is somewhat adaptable to either wet or dry
soils. It is difficult to transplant because of its taproot. The
leaves are alternate, obovate to elliptic and lustrous dark green in the
summer. They are 3 to 6 inches long and 1 1/2 to 3 inches wide, entire
or remotely toothed. Fall foliage is a mixture of scarlet, purple,
orange, yellow and green. The bark on young trees is smooth, grayish
and flaky. On older trees, the bark is dark gray to almost black and
broken into thick, irregular ridges which are checked across into short
segments, giving it a block-like or alligator hide appearance. Branches
become densely twiggy with age and have numerous spur shoots.
Height:
Black tupelo reaches a height of 30 to 50 feet with a spread of 20 to 30
feet. This species is hardy in zones 4-9.
Shape:
Black tupelo is a large shade tree that is somewhat pyramidal when young
with densely set branches. In older trees the spreading and often
horizontal branches form and irregularly rounded or flat-topped crown.
Fruit/Seed
Description/Dispersal Methods:
Black tupelo is polygamo-dioecious (having male
and female flowers on separate plants, but these plants having perfect
flowers as well). The flowers are small, greenish-white borne in
peduncled clusters. They are insignificant and appear in May. The
fruits are bluish-black, small and oblong. They mature in September and
October. Birds primarily disperse the seeds.
Range within
Maine:
This species is
found in very wet areas in Sagadahoc, Cumberland, Androscoggin, southern
Oxford, Kennebec and York Counties.
Distinguishing
Features:
Distinguishing
features of the black tupelo include the consistently spectacular fall
color; blocky ornamental mature bark; and horizontal branching and
flat-topped crown with age.
Interesting
Features:
The wood of the
black tupelo is heavy, fine-grained, very tough, but not durable. It is
used mainly for pulp.
Black tupelo is
also a good honey tree.
Relationship to
Wildlife:
Many birds and
animals eat the fruit and deer eat the young sprouts. Because this
species tends to have cavities, many birds and animals use it for
nesting.
Landscape Use:
Black tupelo is
excellent as a specimen tree and in naturalized areas. It is also a
good tree for streets in residential areas, rather than heavily polluted
areas.
Common
Problems or Pests of the Tree in Maine:
Cankers, leaf
spots, rust, tupelo leaf miner and scale attack this species. Black
tupelo is also often affected by fire, particularly if it is growing on
a dry site.
