Walking under the largest wisteria growth in Japan gives the sensation of a pink sky. It’s an absolutely stunning vine-in flower, but it grows aggressively and is considered invasive in non-native areas, especially in the Southern United States.

Situated in Ashikaga Flower Park in Japan, this plant spreads over an area of a magnificent 1,990 square feet or half an acre. It dates back to 1870 making it nearly ancient. It’s structured on steel support in order to hold out against the potential to get heavy and for the visitors to walk peacefully underneath it.

This plant can be grown easily and fast. Climbing up to 20 m above ground, it can grow in poor-quality soil and can thrive in the hot sun. Well-drained, moist soil is best for it and it is adaptable to a range of soil pH. Flowers are produced usually after the first 5 to 10 years.

As it is a nitrogen fixating plant, Phosphorus fertilizers are recommended over Nitrogenous fertilizers by growers. Due to its incredible strength, strong support must be provided, or else it can even crush wooden posts and damage gutters. Leaves grow alternatively and its lightly fragrant purple, violet, pink or white flowers are produced in dangling racemes. Despite its arresting looks, the seeds of this plant are poisonous and there have been several cases of poisoned children and pets over the years.
