I have a raised percolation area and it has grass and weeds growing on it. I would like to know is there anything I can plant on it that will have nice flowers and maybe take over from the grass. It has been suggested to plant a lawn there but I thought I would get some opinions on it. I have a good large lawn already only planted last year so my garden is only new (blank canvas!)
You could have a wildflower area with some natural-looking shrubs, such as hydrangeas, potentilla and hypericum near the boundaries. The wild flower area could have spring bulbs and would look great in spring, mowed off in mid-summer.
