Multi season gardens often require a bit of preplanning. The flowering times of many plants don’t often coincide with end of season needs. Cross-over plants, or plants that can carry the garden through a change of season, can help provide color while the previous season’s borders die back and new season plants have not yet bloomed. Choose late summer blooms like Sedum, Black-eyed Susans and Helenium species. The ornamental grasses are another choice with many color choices. With a little planning, the change of seasons can be seamless in the garden.
