Types of willow trees
There are hundreds of willow tree types, but the following are some of the most notable ones. If you are looking for willow trees that go beyond just being ornamental plants, here are the types of willow trees that you should check out.
1. Almond Willow (Salix Triandra)
This one is named as such because of its olive to dark green and almond shaped leaves. Yellow catkins of the almond willow appear during spring, along with its foliage. It is a medium size willow, growing to only 35ft. It is, however, prized for its many uses.
One, it is extensively used in honey production through producing nectar. Two, it is also used in basketry and as a biofuel source. The inner bark of almond willow is also dried and powdered to be used as flour. Overall, it is also a good ornamental shrub for hedging and for soil erosion control.
2. American Pussy Willow (Salix discolor)
Generally, pussy willows are cultivated because they are important in floral design. They are also popular in landscaping specifically in rain gardens and in hedges. This one grows from a central stem which can be shaped like topiary. It is also usually planted along ponds and riverbanks as border plants.
It grows in between 2-25ft with up to 12ft of spread. It has red branches, and small green leaves. Overall, it forms a dense, cotton bud like appearance in the garden especially when the pearl white catkins appear.
3. Arctic Willow (Salix Arctica)
As the name implies, Arctic willows’ native range would be rocky and heavily snowy locations. As a matter of fact, it is one of the few woody plants that only grows in the northernmost parts of the world.
It is a small willow shrub which is perfect for rocky, winter gardens. It has clumps of glossy, dark green leaves, with bicolored stems of red and green, and produces purplish red catkins during spring. It grows to just 5ft max.
4. Bebb Willow (Salix bebbiana)
This willow grows from multiple stems, reaching a height in between 10-30ft and usually grows alongside streams, bogs, and lakes. Its dull green leaves are ovate, lancing, and smaller than the leaves of most willow trees. It is also called the diamond willow because the unique diamond marks on its twigs.
The bebb willow is used mainly for carving and woodwork. It is not that popular for landscapes because it is prone to diseases and does not last very long. Nonetheless, once its roots have been established, it is basically drought resistant.
5. Brittle Willow (Salix Fragilis)
This one is also called the crack willow. It is interestingly called as such because of its distinct twitching sound whenever the branches fall or break. It is sometimes mistaken for the white willow because of its light green, small, and ovate leaves. Unlike some willows, this one does not have a hairy underside.
Nonetheless, male crack willows produce yellow catkins while females produce white ones. It grows to up to 40ft, with twisted branches, cascading in random directions. This one is endemic in Europe and Western Asia.
6. Corkscrew Willow (Salix matsudana Tortuosa)
This one is a part of the Chinese weeping willow family. It gets its name for its twisted, upright, dark brown to black branches which is attractive for winter gardens. It has long and narrow leaves, dark brown, furrowed bark and fuzzy, yellow green catkins that bloom during spring.
It grows from multiple, crooked stems and reaches a height of 20-40ft and at least 20ft of shade. As such, it is used for borders but could also be trained to grow low, enough for bonsais and for floral arrangements. It is also called the Scarlet Curls.
7. Dappled Willow/Japanese Willow (Salix integra ‘Hakuro-nishiki’)
This attractive shrub is also called the Flamingo willow or Japanese willow. It is distinct for its variegated, long and pointed foliage with flecks of pink and white all over, arranged in opposites instead of an alternating pattern.
Another distinct characteristic of this willow is that it sheds its colorful leaves during fall and then the stems and leaves turn into a scarlet red color during winter. It is perfect as a border plant or as a focal point in winter gardens. It grows to only 10ft (some cultivars grow to up to 15ft).
8. Dwarf Willow (Salix herbacea)
If you want the weeping form of the willow but you have a more compact space, like patios, balconies, and small gardens, dwarf willow is the perfect choice. It is hardier than most willow types as it could tolerate a wide range of soils and climates.
It is distinct for its dark green and twisted foliage, its round shape, glossy texture and finely toothed margins. It also has the signature arching branches but it would not reach the ground. It only grows at a max height of 5ft and is also called the snowbed willow. Male dwarf willows produce red catkins while females produce yellow catkins.
9. Goat Willow (Salix caprea)
This is another pussy willow known for its oval leaves with pointy ends, dark green color and glossy upper side and waxy undersides due to its whitish gray hairs. Its bark is also notable for its dark grayish brown color and branches that turn smooth in maturity.

10. Golden Willow (Salix Alba Var. Vitellina ‘Yelverton’)
This one is a hybrid willow, made from cross breeding weeping willow and alba. Its foliage cascades down in a weeping manner, with a dull green color which turns to glossy, deep green leaves as the seasons progress.
In its winter dormancy, its branches sport a striking yellow, orange, and gold color, like the burning bush, making a winter visual display. This is also where it gets its name. It grows up to 70ft with a shade that goes to 40ft. It is good for hedges, borders, and screens.
11. Hooker’s Willow (Salix hookeriana)
This willow is native to coastal regions, as such, it is also called the coastal willow or dune willow. It could grow to up to 26ft in a bushy growth habit. It creates a dense foliage composed of glossy, and oval shaped deep green leaves.
This one is also a part of the pussy willow family, blooming white catkins during spring. This one can be found in canyons and marshes.
12. Narrowleaf Willow (Salix exigua)
True to its name, it has narrow, lancing, dark green leaves. It is also called the coyote or sandbar willow. While it is a shrubby willow, it is significant because it is used in producing wood poles for construction because of its known flexibility. Growing to up to 15ft only, it is also used in making rustic design furniture.
It has a dark gray bark with vertical furrows. It tolerates drought and flood prone areas as well as a range of climatic conditions. It has been listed as endangered due to the demand for it in construction. Nonetheless, it is still planted as container shrubs used as ornamental plants in home landscapes.
13. PeachLeaf Willow (Salix amygdaloides)
This medium size willow gets its name for its peach like leaves. It grows either from single or multiple stems and grows in between 13-90ft with a spread of 35ft. Its foliage is olive green, narrow, lancing leaves, finely serrated edges and with white undersides.

14. Purple Osier Willow (Salix purpurea)
As the name suggests, the purple willow is distinct for its purple bark at youth which turns dark grey at maturity. It does not grow tall (just reaching 10-12ft). It has the typical cascading branches of weeping willows, with long, narrow, glossy blue green leaves.
Its catkins bloom in the spring, sporting red or purple colors instead of the typical yellow, white, or green catkins. It is planted for hedging and in erosion control. It is also notable for its medicinal properties specifically of salicin, a natural pain reliever, which is found in its bark.
15. Scouler’s Willow (Salix Scouleriana)
This one is cold hardy and could thrive in dry environments unlike most willow types. It grows from upright, multiple, fibrous, dark brown stems, and grows to just 22ft, making it a beautiful landscape shrub. Its leaves are lancing, with a pointed base, wavy, toothed margins, and brown green color.
It is made scenic by its white catkins and hairy fruits. While it is generally used for carving purposes, it is also functional in prohibiting soil erosion so it is mostly planted along riverbanks and streams. It gets its name from its discoverer, John Scouler.
16. Weeping Willow (Salix babylonica)
It is also called the Babylon willow and is the most recognizable willow out there. It is native to China and is a fast-growing willow that reaches 80ft at maximum. Its weeping form is due to its pendulous growing habit.
Its leaves are long, narrow, and yellow brown most days but turns bright yellow during winter. It also blooms buttery yellow flowers during spring.
It makes a beautiful focal point in large landscapes or in pond and lake edges. They are however, short-lived, only being around for 30 years but with a fast growth rate of 10ft per year. It is beautiful during windy days as the branches sway with the softest breeze. This is the iconic willow tree from the movies.
17. White Willow (Salix alba)
This one gets its name for its green leaves with white undersides. It has a large size, but it is not popular for landscapes because it is vulnerable to a willow fungus which weakens the wood overtime and gives it a distinct diamond form. Its stems are yellowish to white and drop in a cascading form.
The leaves are also showy, starting bright green at first and then turning to dark green and then golden yellow. It grows in between 50-100ft and the stems are used in basketry. This one is a very fast-growing willow which grows along river and stream banks as well as in ponds.
18. Yellow Willow (Salix lutea)
This one is a native of North America found in lakes and stream banks. It has light green and glossy leaves with an ovate shape but elongated, arranged in an alternating pattern. The stems are reddish green and bloom yellow green catkins during spring. It grows to up to 15-30ft, fast growing, and is good as an ornamental shrub especially along bodies of water where erosion is quite common.
How to grow and care for willow trees

Sun and shade
Willows need four hours of direct sunlight every day. Plant them in locations where they get full sun and partial shade.
This tree can tolerate all types of soils, but it would thrive best in constantly moist, slightly acidic, and well-draining soils.
During the first year of growing, willows need to be watered every week. As soon as it establishes roots, watering becomes less frequent, only requiring water if the soil becomes too dry.
Overall, willows do not require fertilizer. But if you see the leaves dying out, a good intervention would be applying a 20-20-20 fertilizer during spring.
Regular pruning is required during the willow’s early years. After that, only prune during late winter or early spring to maintain its shape.
Where do willow trees grow?
Willow trees extensively grow in moist locations and where they could get full sun. Geographically, these trees can be found growing all throughout the temperate areas of North America, Asia as well as Europe.
