Medium-size tree with a compact, narrow pyramidal crown that becomes narrow ovoid when mature. In crown form it is comparable to ‘Frans Fontaine’, but with somewhat thicker twigs. The leaf is also somewhat bigger and a darker green than in other cultivars, and in autumn it turns brownish yellow to golden yellow. In the winter months, the withered leaf remains on the tree for a very long time, as also happens with Fagus sylvatica. Root growth is relatively close to the surface. The rotted leaves are good soil improvers. Very suitable for use in (narrow) streets and housing estates, but the slender shape can also have architectural value in gardens and parks.
Carpinus betulus 'Lucas' can eventually reach a height of 10 m, depending on the site and climate conditions.
