You may also want to try C. montana rubens or C. spooneri. These two tolerate some shade while still providing an exciting flower display. C. vitalba is a species which can be used to cover flatter ground and is seen sometimes alongside roads, crawling through one to two-foot grass. Because this species is a rampant grower, be careful with it in small gardens. Another unusual effect results when clematis hybrids are intermixed with aging junipers. Place the roots outside the junipers and at an angle. Use large- flowering hybrids because they like their roots shaded and also because their rather sparse foliage and stem work grows delicately into the neighboring plants. Species clematis cannot be recommended for this kind of mix because their branches can choke and overrun other plantings within a couple of years. A beautiful bonus comes with some species clematis: the fluffy seed heads during fall and winter, ending in early spring when pruned off. Others, such as C. alpina, C. macropetala, and some of the large flower¬ ing hybrids (‘Barbara Dibley’, ‘Dawn’, ‘Miss Bateman’, ‘Nelly Moser’, ‘The President’) display seeds all summer and fall until rains destroy them. C. orientalis, C. tangutica, and C. vitalba hold their seed heads the longest.. .when winter sun shimmers through the bare trees... . Susanne F. Foster has worked with clematis as a hobbyist and professional for over fifteen years. She formerly operated Tissue & Liners, Inc., a wholesale nursery specializing in climbers, located in Woodinville, Washington. She also teaches horticulture at local community college. Vines to View Locally Washington Park Arboretum by Jan Pirzio-Biroli When Brian Mulligan became director of the Arboretum in the 1940’s, he acquired for the collections a large number of rare vines, which to this day constitute an extremely valuable genetic resource. Many roses were planted along the Broadmoor fence and allowed to scramble into nearby trees. Climbing vines (including Actinidia species and Akebia relatives) were established at the base of native conifers throughout the Arboretum. For example, in the Winter Garden a superbly handsome specimen of Hydrangea anomola ssp. petiolaris has risen more than thirty feet against the trunk of a Douglas fir. The same species grows in the Camellia Section near its close relative, Schizophragma hydrangeoides. Adjacent to the Visitors Center parking lot such famous old roses as ‘Alistair Stella Gray’ and Rosa brunonii ‘La Mortola’ have been pruned so that, temporarily at least, they resemble sprawling, heavy-flowering shrubs. Propagules of the original plant of Rosa mulliganii have been established in the north end of the Brian Mulligan Sorbus Collection
