Wisteria floribunda 'Snow Showers', also known as 'Shiro Noda', is a Japanese wisteria variety with long, fragrant, pure white flowers in late spring. It's a vigorous climber that can reach heights of 20-30 feet, making it ideal for trellises, pergolas, or fences. It thrives in full sun to partial shade, preferring well-drained, fertile soil.
