Tilia caroliniana subsp. heterophylla (syn. monticola)

Very distinct from all other species in the combination of white, very finely hairy backs to the potentially huge foliage that emerges with a deep maroon tint, making a spectacular sight. From the Eastern USA and one of the finest limes in cultivation, but very rarely seen and for no good reason. Splendid specimens can be seen at the Sir Harold Hillier Gardens in Hampshire for example. Scented white flowers in summer. Up to 20m or so.
