Clematis orientalis is extremely robust: clematis wilt, mildew, hot south-facing walls, little aeration or dryness are no threat to them. "Golden Tiara®" (clematis Kugotia) is one such clematis, and is included in our assortment for being a top performer. It was a chance offspring seedling of clematis "Golden Harvest," has big, showy flowers that open fully, and a remarkably long flowering period. The leaves of clematis orientalis are delicate and airy, and while the foliage won't provide a dense foliage wall, its contrast is amazing on darker facades!
Clematis tangutica and clematis serratifolia are the main varieties within this group
The location can be sunny to partially shaded; soil should be fresh, humus-rich, and well-drained. A shaded base and wind protection are not essential for this clematis. Distance between plants: 1.5 - 3 metres. >>> Price
These are petiole ('leaf tendril') climbers that also exhibit a trailing habit (so may also grow with overhanging shoots). The clematis of this group are extremely robust, resistant to clematis wilt, and can withstand dry environments. Growth speed and density of leaves: moderate, lasting from April to October with fine leaves. Plants reach a height of about 3-4 metres. Flowers are somewhat nodding, like yellow lanterns, 2 - 8 cm in size, depending on the variety ("Golden Tiara" has large flowers), flowering from July to October. Has satiny, fluffy seed heads, which bring added interest in fall/winter. If you choose a variety other than "Golden Tiara," keep in mind: the yellow flowers open differently depending on the species and variety; some varieties hardly open at all and remain as unopened bells. Flower size, flowering time, and flowering duration vary greatly depending on the variety.
There are two wasy to prune the plant, depending on the height of the trellis:
For small trellises (up to 2.5 metres): pruning should be done as for "group 3"-- reguvenation pruning at the end of the year at 20-60 cm above the ground.
For larger trellises (up to 5 metres): perform only a thinning in spring, cutting just above the stronger new shoots. Fowering will begin 2-3 weeks earlier with this method.
Choose closely-meshed (narrow) arrangements in a 25 - 35 cm grid. Vertical axes should dominate so that the trellis forms 'standing rectangles' instead of squares. See below for suitable trellis shapes / cable systems. The 5050 wire rope trellis is a good choice and can be used with steel rods. Easy kits (basic and basic-s-) are enough; sometimes the mini or light kits may be sufficient, but a trellis in the medium range allows for optimal development.
