It’s all about timing. As Father Hugo’s rose finishes flowering in early spring, the flowers of Jerusalem sage step in to continue the show alongside ‘Monte Cassino’ clematis.
Large-flowered clematis hybrids, with their longer period of bloom, can act like a bridge, linking a succession of blooms over a season. For instance, ‘Monte Cassino’, a rich red clematis, makes a worthy partner with both yellow-flowering shrub roses and perennials. In my garden, Father Hugo’s rose (Rosa hugonis) and ‘Monte Cassino’ put on a spectacular show in early to midspring. But after the rose fades, Jerusalem sage (Phlomis russeliana) picks up where the rose left off, continuing the same pleasing dusky-red and soft-yellow color combination through the rest of the spring season.
Mixing small-flowered clematis hybrids with herbaceous perennials is where I really have some fun. Brightly colored cultivars like ‘Gravetye Beauty’ (Clematis ‘Gravetye Beauty’) add great presence to a combination when paired with an imposing flat sea holly (Eryngium planum). The crimson-red flowers of ‘Gravetye Beauty’ seem to float above sea holly’s violet-blue umbels from midsummer to autumn.
With such a vast selection of colors, flower forms, and growth habits to choose from, it is best to proceed fearlessly when introducing clematis to your garden. Be guided by the prevailing wisdom, but be a little irreverent, too, so your garden will be your own. Clematis can be dazzling when combined with most other blooming plants, and they are great fillers for areas with seasonal blahs. If you get truly hooked, you may end up like me, trying clematis with everything.
