They love the wet stuff. That’s the thing about Salix. Four hundred plus species, ranging from ground-hugging mats to giants scraping the clouds at ninety feet. You can find them in soggy bogs or stubbornly adapting to dirt that’s bone dry. The leaves? Narrow strips. Roundish blobs. It’s chaotic, botanical variety.
Here is the bad news, up front.
Their wood is brittle. Snaps in wind. But worse is the root system. Invasive. Hungry. If you plant one near your septic line or main water pipe, it will find the gap. It will squeeze through. Then you pay a plumber to dig it up. It happens. Every. Single. Time.
01 Weeping Willow (Salix babylonica )
The poster child of sad landscape trees. Salix babolonica hangs its branches like it has too many problems to discuss. Looks great on a pond edge. A specimen in a big yard. But thirty years is a long time, and it doesn’t last. It grows fast—ten feet a year—so it pays you back quickly for the wait. Then it dies.
Zones 6-9 | 35-50 ft | Full sun
02 Goat Willow (Salix caprea )
Also known as the European pussy willow. People want those fuzzy catkins. Keep it pruned. Use it for a screen. It doesn’t grow from cuttings easily, unlike the others. You need a male and a female to get seeds. Romance, basically.
Zones 5-8 | 12-30 ft | Sun to shade
03 Pussy Willow (Salix discolor )
The floral industry eats this one up. Unlike the goat willow which grows as a messy thicket, S. discolor can be forced into a small tree shape. A single central stem. Much more polite.
Zones 4-8 | 2-25 ft | Sun to shade
04 Bebb Willow (Salix bebbiana )
Northern stuff. Thickets by streams. Carvers like the wood. Landscape designers? Not so much. Short life span. Bugs love it. It’s basically a wild wetland plant that got into your backyard. But once it’s established, it laughs at drought.
Zones 3-7 | 10-30 ft | Shade to sun
05 Corkscrew Willow (Salix matsudana ‘Tortuosa’)
Twisted. Seriously. It looks like it’s having a seizure in slow motion. Good for winter interest because it has no leaves. People make bonsai out of it. It’s related to the weeping type, but cooler. Tortuosa is the star, though Golden Curls exists if you want gold.
Zones 4-9 | 20-50 ft | Sun to shade
06 Narrowleaf Willow (Salix exigua )
Coyote willow. Rustic furniture maker’s best friend. The bark is gray and furrowed, nice to touch. Endangered in the east. Fine in the west. Tolerates flood. Tolerates drought. A survivor.
Zones 2-9 | 6-15 ft | Sun to shade
07 Dappled Willow (Salix integra ‘Hakuro-nishiki*)
Colorful. Leaves start pink. Then green and white. The branches go red in winter. It’s short—maybe six feet tall. Shrub border material. Very decorative. Low maintenance. Just look at it.
Zones 4-9 | Four to six ft | Sun to shade
08 Peach-Leaf Willow (Salix amygdaloid )
Looks like a peach tree? Sure, why not. Doesn’t root from cuttings. Use seeds. Big tree. Fast grower. Dies young. Fills holes in the ground and stops mud from washing away. Usually hangs out with cottonwoods.
Zones 3-5 | 30-50 ft | Sun
09 Purple Osier (Salix purpurea )
Purple stems. Blue-green leaves. Basket makers dream material. It contains salicin, basically natural aspirin, so don’t eat it all, but it has history. Cut it back to the dirt every few years to keep it vigorous.
Zones 4-9 | Eight to 15 ft | Full sun
10 White Willow (Salix alba )
Big. Very big. Up to 100 feet. Weak wood. Don’t put this in your front yard unless you like cleanup duty. Good for filling wet low spots you don’t visit often. S. alba ‘Tristis’ is sold as “golden weeping,” which is a lie if you know what you’re buying, but whatever.
**Zones 4-9
| 50-100 ft | Sun**
11 Scouler’s Willow (Salix scouler )
Deer food. Elk food. It gets out of control. Invasive potential is real. It grows in mixed forests and eats everything. Carvers like it for diamond willow projects. Just be careful.
**Zones 3-9 | 20
-50 ft | Shade to full sun**
12 Yellow Willow (Salix lute )
Moose love it. Beavers eat it. Fixes flood damage. Grows from seed and cuttings, easy to propagate. Can get over twenty feet. Shrubby but stands up. Western North American staple.
Willows are messy. They are fast. They rot quickly and spread deeper than you can imagine. But there’s something raw about them. Unglamorous, tough.
Are they worth the root damage? Maybe not. But when they do what they want? That’s nature, unfiltered.
The roots don’t care about your property line.
Pick wisely. Or don’t. The earth doesn’t care either way.
