Glycine 'Rosea' (Wisteria) - scented climber - 14 cm pot - Height 65 cm

The Japanese Wisteria 'Rosea' (Wisteria floribunda) blooms in spring, generally between April and May depending on the region and weather conditions. The pale pink racemes often appear before or at the same time as the first leaves, making the display particularly striking. In the years following planting, the flowering gradually intensifies as the plant becomes established. Full sun exposure and regular pruning are the two most important factors for achieving abundant blooms year after year.

Yes, the Japanese wisteria 'Rosea' (Wisteria floribunda) is a hardy plant that easily withstands the cold winters of the French regions, including fairly severe frosts. The old woody stems resist frost very well. However, the early flower buds can be sensitive to late spring frosts: if your region experiences frosts in April, a west or southwest-facing location, slightly sheltered, can delay the blooming of the flowers and protect them. Young plants in pots deserve protection of the container (felt or mulch at the base) during very severe winters.

Japanese glycine 'Rosea' is a plant that requires full sun to reach its full flowering potential. A minimum of 6 hours of 'direct sunlight per day is necessary to produce beautiful, abundant clusters. In a partially shaded location, the plant grows adequately but produces very few flowers, if any. Ideally, plant it facing south, southeast, or southwest, against a wall or under a pergola that retains heat: the heat absorbed by a sun-warmed wall promotes flowering. Avoid shaded or north-facing locations entirely.

Pruning the Japanese Wisteria 'Rosea' (Wisteria floribunda) is done in two stages. In summer, usually in July-August, shorten all the young lateral shoots of the year to 5 or 6 leaves: this summer pruning limits excessive growth and directs the plant's energy towards the formation of flower buds. In winter, between January and early March, prune these same shoots to 2 or 3 buds above their base. Do not touch the long, old, woody shoots that bear the future flower clusters. This double annual pruning is the key to dense and regular flowering.

Japanese Honeysuckle 'Rosea' is an extremely vigorous climbing plant that can grow 4 to 8 metres long and become very heavy when mature. It is therefore essential to provide a sturdy, well-anchored support from the time of planting: a wooden pergola made of treated timber with a good cross-section, metal trellising fixed to a load-bearing wall, or tightly tensioned guide wires are all suitable options. Avoid lightweight or temporary structures that may 'collapse under the weight of the stems after a few years. Direct the first stems towards the support at the time of planting and tie them up regularly to guide their growth.

Japanese Wisteria 'Rosea' (Wisteria floribunda) adapts to a wide variety of soils but performs best in deep, well-drained, slightly alkaline to neutral, moderately fertile soil. Soil that is too rich in nitrogen (amended with fresh manure or nitrogen fertilizer) produces lush foliage but few flowers. Also avoid waterlogged soils in winter, which can suffocate the roots. For heavy clay soils, incorporate coarse sand and well-rotted compost at the time of planting to improve drainage. Add organic mulch around the base to retain moisture in summer.

The Japanese Glycine 'Rosea' is a leading climber for structuring and embellishing a garden. It is particularly majestic when covering a pergola or arbor, where its cascading pink clusters create a most romantic, fragrant, and flowery vaulted effect. It is also suitable for covering an old wall, a fence, or a section of a facade. In combination, it pairs very well with climbing roses, blue or mauve clematis, and spring perennials such as peonies or irises.
