cl. 'tangutica'
|
 |
This deciduous climbing species from Mongolia and north-western China is well known in gardens but is often confused with hybrids between C. orientalis and other similar species, or is wrongly named. The true species has bright green leaves which have serrated margins. They are pinnate to bipinnate , the leaflets oblong to lanceolate, sometimes lobed, irregularly dentate, the serrated margins having pointed teeth. The attractive golden-yellow lantern-shaped flowers, 3-4 cm long have four tepals which do not open fully as with c. orientalis. They are followed by large fluffy seedheads. |

cl. 'terniflora'
|
|
This Japanese climber is deciduous in cold climate but can be evergreen in mild locations. It was known to North American gardeners as C. paniculata or the “sweet fall scented clematis”. In later years, it was renamed maximowicziana by taxonomists, now being correctly known as ‘terniflora’. It needs to be planted in a hot, sunny position to achiever the best crop of flowers . The leaves are pinnately 3-5 foliate, the leaflets cordate to ovate, entire and usually a very dark green. The hawthorn scented, star-like flowers are 3cm wide, with four narrow white tepals and white anthers. They are produced in great abundance in panicles and are followed by attractive seedheads. It is a vigorous plant, ideal for covering fences ,archways, pergolas and large wall areas and growing into trees. |

cl. texensis 'Duchess of Albany'
|
|
A cultivar raised by Jackmans of Woking in 1890, from crossing cl. texensis with cl.'Star of India'. This fine clematis has upright miniature tulip-like flowers which are 5-6cm (2-2.5in) in length. The four tepals are held closely together, opening enough to reveal the pinkish anthers. The tepals are a deep candy pink on the inside, with a darker central bar. They have a nice satin sheen. The thick flower stalk (peduncle) gives the flower a long-lasting quality as a cut flower. Best grown at almost ground level where the flowers can be looked into, however the outside of the flowers has an attractive pink colouring. A very useful garden plant. RHS Award of Garden Merit. |

cl. texensis 'Gravetye Beauty'
|
|
Raised by Morel, France, about 1900. Introduced into England by William Robinson in 1914 and named after his estate Gravetye Manor. Also bears miniature tulip-like flowers, however these open much more than cl.'Duchess of Albany' for example, perhaps a little too much, giving a gappy appearance to the flower as it ages. The four to six tepals are a very deep rich red and taper to a point, recurving as the flower matures. Reddish brown anthers. The flower, when fully open, measures about 6-8cm (2.5-3.5in) across. This cultivar is best grown at ground level through other ground cover plants, or even summer bedding plants, where its colourful flowers can best be enjoyed. |

cl. triternata 'Rubromarginata'

|
This deciduous cultivar raised by Cripps & Sons in England in 1862 by crossing C. flammula with C. viticella Rubra. It is a splendid free-flowering plant which is highly scented of hawthorn and no widely known despite its age as a cultivar. It is vigorous in habit when fully established and produces clouds of narrow, four–tepalled, star-like flowers that are white with wine-red edges, 3-4cm across, with creamy anthers . It is useful for growing into small trees or large shrubs, on fences or large wall areas. |
