One of my favorite backyard waterfalls is our vertical waterfalls that's designed for height. These are garden waterfalls that are not finished in the back and need some type of support for mounting. My recommendation is mounting from a structure that uses lattice board. The possibilities from mounting these beautiful waterfall rocks from lattice board is endless when it comes to climbing flowers. Climbing plants like clematis, roses, honeysuckles, morning glories, jasmine, mandevilla, sweet peas and a host of others make excellent choices for these amazing water garden waterfalls. Our outdoor waterfalls look very captivating with plants climbing, hanging and engulfing our artificial rocks for absolutely gorgeous and peaceful flower gardens.
