White Japanese Wisteria Plants

Wisteria Shiro-noda

Also known as Wisteria Longissima Alba, this is a lovely climbing plant with extra long pea like flowers which are white with the faintest lilac tinge. It has a delicate scent, good autumn colour and interesting bark. It will climb to 28' but needs support as it does not self-cling.

Wisteria floribunda alba Shiro-noda does best in fertile, moist, free-draining soil and a sunny site. It requires pruning twice a year to ensure good flowering, two months after flowering and in mid-winter. It is reasonably healthy but needs nurturing for the first year after planting. It is fully hardy and will survive temperatures down to -15C.

Although wisterias are grown primarily for their flowers they also provide architectural shape with attractive winter bark. The autumn colour is decent, so this is a three season plant.

Great for your garden:

Wisteria floribunda Alba Shiro-noda is a wonderful climbing plant providing a superb flush of exceptional scented flowers in June just as the leaves begin to emerge. The flowers are white with a lilac tinge and can reach up to 2' in length.

As it needs sturdy support it is best grown on wires 12" apart against a sunny wall. It is also quite spectacular grown on a pergola when the long racemes can hang down to be admired from below. Due to its luxuriant growth it is best on its own as a specimen.

• Wonderful white flowers with lilac tinges
• Will grow to an eventual height and width of 8m x 4m
• Lovely delicate sweet perfume
• Fully hardy

Look out for:

Shiro-noda wisteria is generally disease free, although it can be prone, on occasions, to leaf spot and powdery mildew. Watch for yellowing leaves and honeydew (sticky coating on leaves). If these are seen then mealybugs may have infested the plant. Treat with a proprietary control.

All parts of the plant are poisonous and will cause severe stomach problems if ingested. It needs pruning twice a year. Two months after flowering the long shoots should be cut back to 5 or 6 buds from the stem and then, in mid-winter, it should be cut back again to 2 or 3 buds from the stem.

Trivia:

Previously classified as a Wisteria multijuga variety, it has also been sold under the names Snow Showers and Longissima Alba. 

Shiro means white, and Noda is a region in Osaka city.

How to grow Wisteria multijuga Shiro-noda:

Wisteria floribunda Alba will need care while establishing.

It will need a fertile, moist well-drained soil and a good root run. Plant in a hole substantially larger than the rootball and backfill with a multipurpose or suitable garden compost. Firm in well and water well. Mulch around the roots and feed with a general purpose fertiliser in spring and summer.

It will need the support of a pergola, pillar or vine eyes and wires when grown against a wall. The plant is vigorous with strong growth and so the support should be sufficiently sturdy.
