Shown before the RHS in 1903 by Messrs Cripps of Tunbridge Wells, UK, under the name Acer linearilobum purpureum gracile 'Crippsii' and received an RHS Award of Merit 1903 with the comment 'A very elegant, perfectly hardy Japanese maple, with slender deep crimson leaflets, but with a sad burden of a name.' It appeared in the Hillier's catalogue of 1914 as Acer palmatum 'Crippsii'. The red leaves are a late flush and serve to illustrate an interesting point. During the spring of 2013 young leaves were lanceolate linear with a toothed edge as can be seen here - but by July 2013 the leaves had changed to linear entire which seems to be the norm for mature leaves. (N.B. The Maple Ridge Nursery on-line says of 'Atrolineare', 'The late summer growth tends to have much wider lobes'). The plant shown is SHHG 1976.4166 U taken 2 October 2012 (Sir Harold Hillier Gardens).
