Size and Method of spreading:

Rock cotoneaster is a low shrub reaching 2 to 3 feet tall and spreading 6 to 8 feet wide. The horizontal branches create a dense layer effect, similar to a ground cover.  This is a trailing plant that can be used as a low-growing shrub or ground cover.   Trailing groundcovers have trailing stems that spread out from the central root system.  These stems spread out horizontally over the ground, but do not root to the ground.
