Family Salicaceae (Willow family)

Plant identification

Willows are deciduous trees or shrubs with invasive roots. The weeping willow is most common; shrub types are used more for their colorful buds or catkins, stems, or contorted shape.

*Some species of Salix are invasive weeds. Other types of plants may be better choices when planting.

Optimum conditions for growth

Willows do best in full sun with ample water. They can tolerate almost any soil type and any climate zone.
