To plant and maintain a flower border, with a good scheme for colour, is by no means the easy thing that is commonly supposed. I believe that the only way in which it can be made successful is to devote certain borders to certain times of year; each border or garden region to be bright for from one to three months.
Nothing seems to me more unsatisfactory than the border that in spring shows a few patches of flowering bulbs in ground otherwise looking empty, or with tufts of herbaceous plants just coming through. Then the bulbs die down, and their place is wanted for something that comes later. Either the ground will then show bare patches, or the place of the bulbs will be forgotten and they will be cruelly stabbed by fork or trowel when it is wished to put something in the apparently empty space.
