Well. I have hundreds of plants...at least.
i disagree with planting perennials in drifts simply because they grow so large anyway. I grow rudbeckias in drifts, cosmos, argyranthemums, heathers, dwarf kniphofias, certain verbenas like Rigida and Homestead Purple, osteospermums, cannas, small grasses, etc., but I enjoy the variety of plants I have so could never restrict myself to any number.
the disadvantage of growing en masse or in drifts is that at certain times whole swathes of planting is dormant, dying down, or not doing anything.
