Cultivar Close-up: Quercus robur 'Timuki'

It was named after the location in Latvia where the original tree was found, a spontaneous seedling with outstanding purple foliage. The foliage keeps it purple color all season and will even darken (nearing black at times) as the season wears on. This selection was first propagated from the ortet in 1997 and was registered in the Czech Republic in 2010. ‘Timuki’ was published in Enzyklopädie der Gartengehölze (Bärtels 2001) and Acta Horticulturae (2011). This selection is said to maintain a straight central leader and develop a pleasing pyramidal shape in youth, broadening to a typical decurrent shape at maturity. This selection is only offered in Europe at this time and can be found at Pavia Nurseries, Bömer Nursery, and a few others.
