White Japanese Wisteria Plants

Wisteria Floribunda Macrobotrys Alba

Wisteria floribunda macrobotrys Alba is a lovely climbing plant having extra long pea like flowers which are white with lilac tinges. 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.

It requires 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 -15 degrees C.

Great for your garden:

Wisteria floribunda macrobotrys Alba 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.

Look out for:

Wisteria floribunda macrobotrys Alba 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:

Although we grow wisterias primarily for their flowers they also provide architectural shape with very attractive winter bark. The autumn colour is not spectacular but good and so this is a three season plant.
