Product description
This is a rare and highly sought-after Japanese cultivar that stands out from the crowd by producing "double" flowers. Each blossom is packed with extra petals, giving the deep purple racemes a dense, rosette-like appearance. Because of these complex double blooms, the flowers hold their shape and last significantly longer on the vine before finally dropping.
To care for 'Violacea Plena', you must provide a robust, permanent support system capable of holding massive weight, as the mature woody trunks become incredibly heavy. Plant it in rich, loamy, well-draining soil and ensure it receives at least six hours of direct sunlight daily. Tie the clockwise-twining stems securely to your framework and perform your strict summer and winter pruning to keep the vigorous growth from turning into a tangled mess.
Please Note: When purchasing plants, please consider that each live item is unique and may therefore differ from the images shown, which are for illustration purposes only. The plant will be supplied in a growers pot. Depending on season, some plants may be pruned back to encourage growth and deciduous plants may arrive without leaves.
Garden Plant Size Guide

Plants in larger pots can be multiple years older than their smaller counterparts with more mature root systems and foliage. This makes them able to thrive as a full size plant in your garden quicker than smaller alternatives.
The most common size of pot that garden plants come in are 9cm/1L/3L/5L this is in reference to the diameter at the top of the pot.
9cm potted plants still remain the most popular cost effective option though, they just may take a little patience to allow them to grow into full maturity once planted in your garden.

Instructions
Top Tip
The Wisteria Violacea Plena produces "double" flowers (extra petals), which means the blooms last significantly longer on the vine before dropping compared to the single-flowered varieties.
How to Water
To water Wisteria Violacea Plena, soak deeply once a week in year one to build strong roots. Once mature, let the topsoil dry out, but keep it moist while its double purple blooms develop. Always water the base.
How to Plant
To plant Wisteria Violacea Plena, dig a hole twice as wide as the rootball but exactly the same depth. Enrich the excavated soil with a generous scoop of compost to ensure a nutrient-rich loam. Place the vine in the hole, making absolutely sure the knobbly graft union sits safely above the soil line. Backfill firmly, tie the main stem clockwise to your sturdy support, and water deeply to settle the roots.
