This cultivar originated in the 1980's at Winterthur Gardens where it was found and selected (but not yet named) as a pollinator for the already existing V. nudum 'Winterthur'.  Grown at Longwood Gardens since 1993, it was finally assigned the name 'Longwood' with the permission from Winterthur Gardens.  A superb compact addition to the nudum "family", growing only 4-5' tall with a 5-6' spread after 15 years.  Habit is a broad rounded form and very dense.  Leaves are a glossy green, turning rich wine red in the fall.  Fruit set is exceptionally prolific.  It has proved to tolerate the stress of full sun exposure as it is growing in an island bed of a parking lot at Longwood Gardens.  Zone 5
