Glycine 'Alba' (Wisteria) - fragrant climber - 14 cm pot - Height 65 cm

Yes, the Glycine 'Alba' (Wisteria floribunda 'Alba') is renowned for its delicate and captivating fragrance, which is well-pronounced without being overpowering. Its clusters of white flowers give off a soft and floral scent, particularly noticeable in the morning and on warm, sunny days. This subtle fragrance sets it apart from some other wisterias with more intense mauve blooms. It is precisely this combination of visual and olfactory elegance that makes it a highly sought-after climber for adorning pergolas and terraces. Placed near a window or an outdoor living space, it pleasantly perfumes the evenings of May and June.

The 'Alba' Wisteria (Wisteria floribunda 'Alba') is a fast-growing climber that can produce 1 to 2 meters of new growth per year in good conditions of sunlight and soil. On a well-established installation, it can easily cover a pergola in 3 to 5 years. This vigor is a spectacular asset but requires planning for a robust support from the start, capable of supporting the significant weight of an adult wisteria. Regular pruning, carried out twice a year, allows to channel this energy towards flowering rather than solely towards vegetative growth.

Glycine 'Alba' generally blooms from mid-April to late May, depending on the region and local weather conditions. Its pendulous clusters of pure white flowers 'open just as the foliage begins to unfurl, making the bloom even more spectacular because the clusters are fully visible. In regions with mild climates, a slight repeat bloom is sometimes observed in late 'summer. Be wary of late spring frosts, which can damage early flower buds: a sunny, sheltered position reduces this risk.

To plant your Glycine 'Alba' against a wall or pergola, dig a hole twice as wide and deep as the 14 cm pot provided, keeping your distance of 'at least 30 to 40 cm from the base of the wall to avoid the dry zone on the ground. Amend the bottom of the hole with compost and install a support (wire, trellis, post) right away, as the glycine 'clings by wrapping its stems. Water abundantly at planting and during the first few weeks. Manually guide the first shoots toward the support; the plant will then become self-sufficient.

The 'Alba' Wisteria (Wisteria floribunda) is a vigorous climber that can become very large over the years, but it is not invasive in the botanical sense: it does not spread spontaneously by seed or stolons in nature in Europe. Its vigor, however, requires serious pruning twice a year to prevent it from getting under roof tiles, choking a gutter, or overwhelming a neighboring shrub. It can also lift light structures under its adult weight, hence the importance of a sturdy support from the start.

Yes, the Glycine 'Alba' (Wisteria floribunda 'Alba') is a very hardy climber that can withstand temperatures down to -20°C, or even -25°C for well-established plants. It can overwinter in the ground without protection in almost all regions of France, including moderate-altitude mountain areas. Its deciduous nature allows it to get through the unfavorable season in complete dormancy without suffering. The only concern is the flower buds, which can be damaged by late spring frosts in April after vegetation has started to grow. Sheltered exposure limits this risk.

Growing 'Alba' wisteria in a pot is technically possible but remains a compromise: this climber is naturally vigorous and develops a powerful root system that quickly feels 'confined in a container. If you wish to 'try, choose a very large, well-drained pot of at least 60 litres, with a sturdy support. The flowering will be less exuberant than 'when planted in the ground, and regular watering as well as spring fertilising will be essential. On a terrace, plan to repot every 2 to 3 years.
