Growing Clematis

Clematis vines are climbing shrubs or herbaceous perennial plants with beautiful flowers in a rich variety of hues. Besides attractive flowers, many varieties can also boast quite a remarkable seedheads. They offer endless possibilities for enhancing the landscape, but in order to achieve the best results, it's vital to learn about their requirements.

Close attention should also be given to selecting the right cultivars as well as to careful preparation of the site. The effort will certainly pay off, as the plants may grow abounding with flowers for many years to come, rewarding us with their growing fullness and lushness.

New varieties come on the market every year including new Polish verieties rised by Szczepan Marczyński in our nursery. Our encycloapedia of plants comprises short characteristics of over three hundred of the most valuable and popular cultivars.

Large flowered and Viticella groups of Clematis

There are known over three thousand of large-flowered Clematis varieties, among which a few dozen are of Polish origin. More than a dozen of them have gained worldwide appraisal and recognition and are cultivated in millions of gardens all over the world in many countries in Europe, both Americas, Asia, Australia and Oceania, e.g.:Clematis  'Niobe' (W. Noll), Clematis 'Generał Sikorski' (W. Noll), Clematis 'Polish Spirit' (S. Franczak), Clematis  'Jan Paweł II' (S. Franczak), Clematis 'Błękitny Anioł' BLUE ANGEL (S. Franczak), Clematis  'Kardynał Wyszyński' (S. Franczak), Clematis  'Warszawska Nike' WARSAW NIKE (S. Franczak), Clematis 'Kacper' (S. Franczak), Clematis 'Westerplatte' (S. Franczak), Clematis 'Emilia Plater' (S. Franczak), Clematis 'Monte Cassino' (S. Franczak) and Clematis 'Matka Urszula Ledóchowska'  (S. Franczak).

Among new beautiful Polish cultivars, raised by Szczepan Marczyński, receiving international approval and awards are: 'Azure Ball' PBR, 'Barbara’ PBR, 'Beautiful Bride' PBR'Bieszczady' EARTHQUAKE, 'Copernicus' PBR, 'Diamond Ball' PBR, 'First Love' PBR‘Hania’ PBR, 'Innocent Blush' PBR, 'Jerzy Popiełuszko',  'Julka' PBR, 'Krakowiak' PBR Viticella group, 'Maria Skłodowska Curie' PBR, 'My Darling' PBR'Mazowsze' VOLCANO, 'Mazury' CRATER LAKE, 'Skyfall' and 'Solidarność'.

It's worthwhile to remember that the majority of double flowered cultivars produce double flowers only during the early blooming in May-June, on previous year's wood, whereas flowers borne on new shoots are single, and may have a slightly different color. The prominent exceptions include: ‘Maria Skłodowska Curie’ PBR, ‘Diamond Ball’ PBR, 'Kaiser' PBR'Kiri Te Kanawa', 'Blue Light' PBR, 'Mazury' CATER LAKE, 'Multi Blue', 'Shin-shigyoku' and 'Purpurea Plena Elegans', Viticella group, that bear double flowers on both old and new growth.

Clematis viticella (Italian Clematis) - A slender climber reaching up to 4 m, with dainty, small (4-5 cm across), deep violet flowers. Hybrids of this species are sufficiently hardy with variously colored blooms, up to 7 cm in diameter, borne from June to September. Cultivars produced by crosses between Italian Clematis and other clematis varieties form the Viticella Group. These cultivars are not only healthier and less demanding but they also stay decorative over a longer period than large-flowered Clematis. Therefore they are excellent plants for beginning gardeners, and for those who lack time for garden work. Superb for growing up fences, wire nettings, arbors and pergolas, or scrambling through trees and shrubs. In the midst of bloom the sight of plants covered with billowing clouds of flowers is truly charming. The following are considered to be among the most valuable cultivars in the group: 'Alba Luxurians', 'Betty Corning', 'Carmencita', 'Emilia Plater', 'Etoile Violette', 'Krakowiak'PBR, 'Mme Julia Correvon', 'Night Veil', 'Polonez', 'Purpurea Plena Elegans', 'Słowianka', 'Venosa Violacea'.

Herbaceous Clematis

Herbaceous clematis form an interesting, though not widely spread, group of climbers. Though of smaller flower stature, in full bloom masses of flowers give a spectacular display. Most of the varieties (e.g. Clematis alpina, Clematis macropetala, the Atragene group and Clematis montana) start blossoming in late April - early May, that is 2 to 4 weeks earlier than the earliest flowering large-flowered hybrids. Many have lower growth and culture requirements, for instance cultivars from the Atragene group, the group and the Vitalba group have hardy stems, while clematis from the Tangutica group will tolerate poorer soil and much drier conditions than any other varieties from the genus.

Clematis'Maidwell Hall' and 'Ballet Skirt'

Assembles cultivars created by selective breeding and crosses between the mountain clematis species flowering in early spring i.e.: Clematis alpina, Clematis chiisanensis, Clematis faurieri, Clematis koreana, Clematis macropetala, Clematis ochotensis, Clematis sibiricaand Clematis turcestanica. They grow up to 2-3,5 m. Charming, though small flowers are borne on old wood during April-June, and occasionally in summer, on new growth, during July-August. In summer and autumn plants carry most decorative silky seedheads. No pruning is required, but if they grow out of the alloted space, you may cut it back any time after bloom is spent in the autumn. They thrive best in neutral or slightly alkaline moderately moist and well drained soils, in semi-shade. Ideal for growing over low fences or scrambling over rocks and old stumps, clambering through shrubs and trees. They make good ground cover and are suitable for container growing. Cultivars: 'Albina Plena', 'Ballet Skirt', 'Cecile', 'Frances Rivis', 'Frankie', 'Golden Dream' PBR'Lagoon', 'Lemon Beauty' PBR, 'Lemon Dream' PBR, 'Maidwell Hall', 'Markham's Pink', 'Pamela Jackman', 'Pink Dream' PBR, 'Pink Flamingo', 'Pink Swing' PBR, ‘Purple Dream’ PBR, 'White Swan', 'Willy'.

Clematis terniflora (Sweet Autumn Clematis). A vigorous Japanese cultivar, often forming a dense tangle of growth. Very popular in the United States. A late flowering variety bearing during September-November a profusion of small, star-shaped, sweetly scented white flowers. Requires a sunny, hot position with a tall, strong support - it may not flower at all during cool summers or when grown in a shaded position. Veriety ‘Early Snow’ starts flowering in September and continues in October, if frosts don't come – even until mid-November. It is non-fragrant variety.

 Clematis monatana 'Freda'
 Clematis montana 'Mayleen'

Clematis Montana group

Clematis montana var. rubens  (Anemone clematis; Indian's virgin's bower). A popular free-flowering species of vigorous, often rampant growth, with stems up to 8 m long. During May and June a mass of rosy-mauve flowers, abundantly scattered over the whole plant, can last as long as a few weeks. Unfortunately flower buds and sometimes stems tend to freeze during severe winters. Another very attractive cultivar of this species is 'Freda'. Although less vigorous, it's appreciated for its lovely cherry-rose flowers and purple-green leaves.

Varieties ‘Elizabeth’ and ‘Mayleen’ a vigorous, profusely flowering climbers. A wall of hundreds of light pink, slightly vanilla scented flowers, 6 cm across, with 4 tepals and yellow anthers on creamy filaments can stay on the plant even for a few weeks in May and June.

A rampant growing florifeorus climber, 'Freda' variety with bright cherry-pink flowers, the tepals with darker edges. 

Clemats Tangutica and Vitalba group

Clematis tangutica (golden Clematis) A delightful, easily grown climber that grows up to 3-5 m. Nodding, yellow campanulate flowers, composed of four tepals, are borne on long, downy stalks during summer (June-August), the later ones intermingled with decorative silky seedheads. At the end of September the plant retreats into winter dormancy and the leaves wither.

Similar in looks, but more valuable are cultivars included in the Tangutica Group (they tend to have bigger flowers, bloom more profusely and over a longer period while the foliage can stay green even up to the end of October), created by crosses between Clematis tangutica, Clematis orientalis and Clematis intricataClematis ispahanicaClematis ladakhianaClematis serratifoliaClematis tibetiana. They are healthy, hardy plants with low requirements - they tolerate draught but will perform badly in waterlogged soil. Excellent for growing up walls and wire nettings and very effective at screening unattractive views. They are suitable for all kinds of gardens as well as for growing in public places. The most valuable cultivars include: 'Bill MacKenzie' - the most vigorous of the lot, with yellow, partially open flowers from early summer until first frosts and green foliage from April to the beginning of November; GOLDEN TIARA ‘Kugotia’PBR - large elongated bright yellow flowers, grows up to 2-3 m; 'Kaśka'  with large, bright yellow flowers, bloom from the end of May even till mid-October. In place of the flowers decorative silky seed heads appear;  'Lambton Park'  is the most attractive and the longest-flowering cultivar from the Tangutica Group - vigorous (up to 4-5 m), with the bulged, slightly open deep yellow flowers.

Clematis Integrifolia and Heracleifolia group

Clematis integrifolia (Solitary Clematis)  A slender-stemmed, scrambling perennial with stems up to 60 cm. From June to September plant covers with bell-shaped nodding violet flowers with recurving tepals. Depending on a variety, flowers can be blue, violet, white or pink. It's a hardy perennial that dies down to the ground each year and survives the winter on food stored in specialized underground stems. Dead stems should be cut out in early spring. As a support you can use neighboring plants, bamboo sticks or stakes, or alternatively you can let it trail along the ground Hybrids produced by crosses between this species and other clematis form the Integrifolia Group. Though still little known, they are very valuable and attractive on the basis of their long and profuse flowering, healthiness hardiness and easy culture. They adapt well to all the familiar garden uses and can be successfully grown on balconies and terraces but also in public places. They are non-clinging in habit with the stems, depending on a variety, between 40 to 200 cm long,but will meander through a border and amongst existing plants in a delightful manner, adding interest to shrubs that have finished flowering (e.g. azaleas that flower beautifully but shortly in early spring, and afterwards they form a monotonous mass of green until the autumn when its leaves variegate), or providing a contrast of color and form. Clematis from this group are charming companions for border roses and other shrubs, invaluable for creating groups and borders. When grown without support, they will spread out over the ground creating attractive covers.

The following list comprises some of the most valuable hybrids: 'Alionushka', 'Arabella' (1994)'Bluish Violet', 'Hakuree', 'Hanajima', 'Heather Herschell', INSPIRATION® 'Zoin', 'Little Artist', 'Olgae', 'Pamiat Serdtsa', 'Rooguchi', 'Rosea''Ryuan', 'Sizaia Ptitsa'.

Clematis  heracleifolia (Tube Clematis) a herbaceous perennial with raised, stiff stems, up to 1 m. Small (2-5 cm across), tubular, sweetly scented, blue-mauve flowers are produced from July to September in large clusters similar to that of a hyacinth, located in the leaf axils. Ideal for scrambling through herbaceous perennials and shrubs. Cultivars created by crosses between this species and other clematis comprise the Heracleifolia Group. The most valuable among them are:

Clematis 'Praecox'

 

Clematis 'Praecox'  raised as a hybrid of Traveler's Joy (Clematis vitalba) and Tube Clematis (Clematis heracleifolia), it's the best ground cover clematis that makes a welcome addition to every garden. Its large dark green leaves, trifoliate with coarsely toothed leaflets, spread densely over the ground. Stems grow rampantly (3-4 m of annual growth), and in just a few weeks cover the ground with a thick carpet, thus inhibiting weeds and preventing soil from excessive heating and drying out. In June and July the plant covers with masses of small, 3-4 cm across, pinkish-mauve flowers, gathered in large panicles. It's sufficiently hardy. The pruning should be hard or moderate, depending on the area to cover.
