Greenspire™ linden is a shade tree with a strong, spire-like shape that will reach about 50 feet tall at maturity with a spread of 30 feet. The heart-shaped leaves turn gold in the fall. In early summer, subtle clusters of fragrant yellow flowers with tan bracts hang below the branches.
The cultivar 'Greenspire' was introduced by Princeton Nurseries in 1961. The name 'Greenspire' was registered as a trademark in 1974, so the correct cultivar name is 'PNI 6025.' Tilia cordata is commonly planted as a street or lawn tree and 'Greenspire' is noted to be more popular than the species or any other cultivar.
