Good tree for western North Carolina. Planted one in my backyard about 11 years ago and it has grown to be an excellent focal point. Needs a lot of room and full sun.

Most of the pics here look like Salix alba 'Tristis'. Dirr claims that the true Salix x pendulina isn't in commerce. Even professional botanists throw up their hands when it comes to sorting out the weeping willows. Is it any surprise that so many of them are mislabeled in the nursery?

Beautiful as they are, weeping willows:

1) outgrow their space incredibly quickly.
2) drop major branches dangerously due to weak wood.
3) outcompete neighbors with their shallow thirsty roots.
4) disrupt plumbing, septic systems, and other manmade structures.
5) carpet the ground with an unending rain of debris.
6) work best in a park setting, not a residential lot.

How can a tree with 'Wisconsin' in its name have a coldest zone of 6??? And no one lists growing it in the northern midwest, let alone Wisconsin.


Or is it confused with the Wisconsin Weeping Willow, 'Tristis' ?

Had very good experience taking branches and putting them in just water and fast draining sand. I could not believe how quickly they rooted! Durban - South Africa

the weeping willow is a very nice type of tree and can be used in many grafts such as weeping cherry, birch, hemlock, etc. You should be very careful where you plant it though because the roots will seek out water. if you have a septic tank or well near a weeping willow they can cause extensive damage to them or even destroy them.

Quite nice as a specimen tree. Weeping Willows look so nice in a garden setting.

They are easy to propagate, just stick a branch in damp soil and most likely it will root.

One drawback is the fall cleanup of all of the willow 'whips' that fall to the ground after frost.

My Grandmother had a giant one in her yard, and I have nice memories of playing in the 'room' that the drooping branches made as they circled the trunk. I always think of my Grandmother when I see one.
