As stated, weeping willows are beautiful but messy, so you might want them where you don't mow around them or where they're dropping all those limbs and leaves in the pond. They also can consume up to 50 gallons of water a day as well and are notorious for invading water lines and messing up foundations. Regardless, they are fast growing and extremely easy to propagate. Just stick a cutting in the ground, keep it watered, and it will root. They're drought tolerant too but will drop a lot of leaves.
