Climbers

Growing climbers

Apart from clematis, there exists a large group of climbing vines worth popularising. Climbers take up little space in the garden all the while giving a spectacular display owing to the mass of greenery they produce: Silvervine Fleeceflower (Fallopia), Dutchman’s Pipe (Aristolochia), Oriental Bittersweet (Celastrus), Trumpet Creeper (Campsis), Vitis, Parthenocissus, Monks Hood Vine (Ampelopsis), Actinidia, beautiful flowers: Wisteria, Trumpet Creeper (Campsis), Honeysuckle (Lonicera) and ornamental fruit: Oriental Bittersweet (Celastrus), Nightshade (Solanum), Ampelopsis, as well as edible fruit: Actinidia, Magnolia Vine (Schisandra) and Akebia. The majority of climbers climb by twining spirally round the support, while others, owing to the presence aerial rootlets e.g. Ivies (Hedera), Climbing Hydrangea (Hydrangea anomala subsp. petiolaris), Trumpet Vine (Campsis), Japanese Hydrangea Vine (Schizophragma hydrangeoides) and Wintercreeper Euonymus (Euonymus fortunei), or adhesive tendril tips, e.g. Japanese Creeper (Parthenocissus), are self-clinging and can scale a flat wall, without added support.

Climbers are particularly useful for covering outer walls of buildings. Apart from their decorative aspect, they also act as insulation during winter, and retain a pleasant coolness inside the house during hot summer days. They also help keep the walls dry by shielding them from the rain, and draining excess water away from the foundations. Creepers are best suited to this end, but you can equally well use ivies or Trumpet Vine, or any other climber on condition that a suitable support is provided.

Climbers can cover unsightly buildings, sheds, warehouses, rubbish sheds, etc. hiding them quickly from view. If you want to have the effect in just one year, you should try Silvervine Fleeceflower (Fallopia aubertii), Hop (Humulus), on clematis belonging to the Tangutica Group e.g. 'Bill MacKenzie' or ‘Lambton Park’ or alternatively, Clematis'Paul Farges' of the Vitalba Group. If you can wait 2-3 years, you can use any climbing vine described in this section.

Climbers can grow up various kinds of fences (np. siatki) (e.g. wire meshes). They will not only provide decoration, but will also screen us from nosy people's eyes and protect us against winter and dust. The following plants are excellent for this purpose: Common Ivy (Hedera helix), Japanese honeysuckle (Lonicera acuminata), clematis of the Atragene Group (especially 'Pamela Jackman'), the Tangutica Group (especially 'Lambton Park'), the Viticella Group (especially 'Etoile Violette' and 'Polish Spirit') and the Vitalba Group (especially 'Paul Farges'), Monks Hood Vine (Ampelopsis aconitifolia), Virginia Creeper (Parthenocissus quinquefolia) and Boston Ivy (Parthenocissus tricuspidata).

The majority of climbers don’t require any special soil conditions, but since they produce a large mass of greenery, they don’t like very dry and poor soils. Heat-loving species, such as actinidias (Actinidia), wisterias (Wisteria) and trumpet creepers (Campsis), prefer warm, sheltered and sunny sites, while Common Ivy (Hedera), Climbing Hydrangea (Hydrangea anomala subsp. petiolaris), Dutchman’s Pipe (Aristolochia), Schizophragma (Schizophragma), Wintercreeper (Euonymus fortunei), Akebia (Akebia), Hop (Humulus) and some honeysuckles (Lonicera) will feel better in a cooler, shaded and moist site.

When planting climbers dig a hole of 50x50x50 cm and fill it with fertile soil. Depending on the species, put the plant 0-10 cm deeper than it used to grow in a pot, at least 30-50 cm away from the wall and 50-100 cm away from the trees. Well chosen and correctly planted climbers can grow for many years, decorating your garden all year round and providing excellent shelter for birds.

Abstract: Actinidia arguta (Siebold et Zucc.) Planch. ex Miq. is functionally a cryptic dioecious plant and successful pollination is crucial for achieving high quality fruit. The extent and bases of morphological variability in female genotypes have been well studied, but here we focus on the males. Mature plants of seven male A. arguta genotypes were studied in 2016 and 2017 during which a suite of phenological and morphological features was measured on ten randomly chosen one-year-old canes on each plant. This analysis was complemented by two other, specialized measures potentially related to pollination efficiency, namely pollen quality, and quantity. The time of bud break was similar each year across all genotypes and the pollen quality was uniformly very high (viability – 95.0–99.9% and germination – 89.0–97.3%). However, the ten genotypes exhibited high variability in both the number of flowers per inflorescence and pollen quantity, indicating marked differences in their flowering potential and efficiency as pollinizers. The male kiwiberry indicators developed in this study – flowering potential and pollen efficiency, appear to be effective tools for the comparative evaluation of male A. arguta genotypes.
