General tree description

Tilia 'Harold Hillier' is a hybrid produced from T. japonica 'Ernest Wilson' and T. mongolica. It is a medium-sized tree with a narrowly conical shape. The leaves are maple-like and three-lobed, dark green above, grey-green and glabrous beneath. They are toothed and variable in size, up to 15cm long though usually less. The autumn colour is a striking butter-yellow. White flowers are produced in June and July.

In the Hillier Manual of Trees and Shrubs (9th edition, 2019, page 463) it is stated that this tree was "raised in 1973 by Nigel Muir who kindly suggested that Hillier Nurseries should name it after Sir Harold Hillier." Up to July 2020, it has not been in production.
