populus detoides "Siouxland"
Populus deltoides 'Siouxland'
Height: 70 feet
Spread: 40 feet
Sunlight: full sun
Hardiness Zone: 3
Other Names: Siouxland Cottonwood
The Siouxland poplar, also called Eastern Cottonwood, produces a large crown of branches that require yearly pruning for maintenance. This fast-growing deciduous variety reaches a height up to 70 feet tall with a crown that spans up to 40 feet across.
The Siouxland Cottonwood tree is a very fast growing, cottonless cottonwood with a rounded head at maturity. This tree displays shimmering foliage which is rust resistant. Cottonless Cottonwood trees are not only a fast growing tree, but it also does well in drought conditions. Siouxland Cottonwood will also
tolerate wet soil conditions.
This tree has large glossy leaves. This Cottonwood tree is pyramidal in form and is fast growing. Up to 4-5 foot of growth per year is not uncommon in good soil. The Cottonwood trees display a yellow fall color. This tree provides good shade and cover for wildlife. Will perform best in full sun to lite shade.
Siouxland Poplar will grow to be about 70 feet tall at maturity, with a spread of 40 feet. It has a high canopy with a typical clearance of 7 feet from the ground, and should not be planted underneath power lines. It grows at a fast rate, and under ideal conditions can be expected to live for 60 years or more.
This tree should only be grown in full sunlight. It is an amazingly adaptable plant, tolerating both dry conditions and even some standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for xeriscaping or the moisture-conserving landscape. It is not particular as to soil type or pH, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments.
This is a selection of a native North American species.
Populus deltoides is a large tree growing to 20–40 m (67–130 ft) tall and with a trunk up to 1.8 m (5.9 ft) diameter, one of the largest North American hardwood trees. The bark is silvery-white, smooth or lightly fissured when young, becoming dark gray and deeply fissured on old trees. The twigs are grayish-yellow and stout, with large triangular leaf scars. The winter buds are slender, pointed, 1–2 cm long (.039–0.79 inches), yellowish brown, and resinous. The leaves are large, deltoid (triangular), 4–10 cm (1.6–3.9 inches) long and 4–11 cm (1.6–4.3 inches) broad with a truncated (flattened) base and a petiole 3–12 cm (1.2–4.7 inches) long. The leaf is very coarsely toothed, the teeth are curved and gland tipped, and the petiole is flat; they are dark green in the summer and turn yellow in the fall (but many cottonwoods in dry locations drop their leaves early from the combination of drought and leaf rust, making their fall color dull or absent). Due to the flat stem of the leaf, the leaf has the tendency to shake from even the slightest breeze. This is one of the identifying characteristics.
Populus deltoides, the eastern cottonwood, is a cottonwood poplar native to North America, growing throughout the eastern, central, and southwestern United States, the southernmost part of eastern Canada, and northeastern Mexico.
It needs bare soil and full sun for successful germination and establishment; in natural conditions, it usually grows near rivers, with mud banks left after floods providing ideal conditions for seedling germination; human soil cultivation has allowed it to increase its range away from such habitats.
It is dioecious, with the flowers (catkins) produced on single-sex trees in early spring. The male (pollen) catkins are reddish-purple and 8–10 cm (2.1–3.9 inches) long; the female catkins are green, 7–13 cm (2.8–5.1 inches) long at pollination, maturing 15–20 cm (6.9–7.9 inches) long with several 6–15 mm (0.24–0.59 inches) seed capsules in early summer, which split open to release the numerous small seeds attached to cotton-like strands.
