Better to cluster multiples or dot individual plants?
What is more interesting and effective in the landscape, to cluster 3 or 4 of the same plant together, or to plant individually?
I am redoing a garden area where I will replant with perennials. Just contemplating whether, instead of planting one of this and one of that, I might be better off in terms of the visual impact by planting fewer kinds, and planting them in groups of 3 or 5 of each thing. I'm thinking about using ornamental grasses, sedums, Rudbeckia Goldsturm, Echinaceas, probably some kind of silver foliaged Artemesia, maybe some asters for the fall.
