Holly

Ilex | Also known as: Ilex, Winterberry | Rating: 0 votes | Print / Pdf

Ilex, commonly called holly, is an evergreen shrub that can grow very high. Small inconspicuous flowers are produced in the summer, and these develop into bright red berries during the autumn as long as both male and female plants are present. Ilex is extremely hardy and grows in aspects from full sun to dense shade. It prefers a well-drained and dry soil, but can tolerate many various compost types. Holly is ideal as a boundary hedge, and can also be planted as a specimen tree or clipped into a shrubby topiary shape.
