I have a street side bed I need to edit! It is about 30' x 4', pretty sunny. I have gone back to work full time in the summers, and our neighbours, who are very O/C about gardens, have been objecting to the bed as it is looking tired and the plantings are not working well. The bylaw officer has been called in twice this month, on the pretext there are too many weeds. I just don't have time to make this bed magazine-worthy and in any case they come out to watch me whenever I do garden...that's really taken the joy of gardening away for me. I dread going into our front yard! So...I need this situation to go away...I need ideas on low-maintenance, attractive plantings for this space. Presently it is anchored by three 4' purplish-red barberries (left end, right end, middle, planted at the rear of the bed) and two mature Styrax trees (between the barberries). On one end is a gorgeous Lem's Monarch rhododendron, on the other a group of spirea, adding pinky-orange notes to work with the barberry. Everything else can go. What would you add to make this border nice all year long, tidy, and low maintenance?
