Softscape
Softscape comprises the living, horticultural elements of the landscape.
More simply put, it refers to the plants. Softscape elements are complemented by hardscape elements, such as pergolas, walls, patios, and walkways.
So why is it incorrect to say that softscape simply means all the elements in one's landscaping that are soft? Well, contemplate this. A tree is considered part of the softscape, but if you are playing catch with the kids in the yard and accidentally run full-steam into a tree's trunk, will it feel soft to you? Hardly, because you will most likely come away with a bruise.
So, to qualify as softscape, an object has to be a plant. It does not have to be soft to the touch...
