Noteworthy Characteristics

Genus name is the Latin name for this plant.

‘Rubykins’ is an upright, compact, slow-growing, deciduous, shrub willow cultivar that typically grows to 6’ tall and as wide over the first five years. Bright red catkins (to 1/2” long) appear in early spring. Narrow, linear, bluish-green leaves are attractive throughout the growing season. Yellow branches in winter.


Willows are generally susceptible to a number of disease problems including cankers, blights, galls, leaf spots, powdery mildew and rust. Potential insect pests generally include borers, caterpillars and scale.
