In spring, the Niobe Golden Weeping Willow white flowers develop as catkins much like those of the Pussy Willow. A beautiful flowering willow tree, the Golden Niobe will grow into the 50 - 70 foot height range with a spread equal in height. As with most any Weeping Willow tree, the Niobe Golden Willow should be planted in full sun away from all types of piping and foundations and no less than 40 feet away from any septic field lines. Weeping Willows are best sited near or on water banks (moist to wet soil areas) where they can spread their long golden branches.
