About
Lonicera involucrata, the Californian honeysuckle, is a deciduous, bushy shrub with sturdy shoots and oval, mid-green, oblong leaves. In late spring, dark-yellow, tubular flowers tinged red appear surrounded by green bracts that turn red. These are followed by shiny-black berries enclosed in conspicuous red bracts � a dual display of ornamental interest. An excellent wildlife shrub for a sunny or partly shaded border.
