Geranium maculatum 'Schokoprinz'

Hardy Geranium Geraniaceae

A particularly good dark-leaved selection of the North American woodland geranium, and one with a rather nice story behind it. ‘Schokoprinz’ was selected by Austrian plantsman Christian H. Kreß of Sarastro Stauden as a chance seedling found in his own display garden. It combined unusually dark, chocolate-brown foliage with rich blue-violet flowers, and proved considerably more vigorous and floriferous than the existing dark-leaved selections. Kreß initially propagated the plant for assessment, while the name ‘Schokoprinz’ was subsequently given by his colleague Maria Ell. 

The result is a wonderfully useful woodland perennial: an upright clump of strongly coloured foliage topped in late spring and early summer by relatively large, blue-violet flowers with a pale eye. The contrast is particularly effective alongside golden or lime-green foliage. Unlike some brown-leaved Geranium maculatum, ‘Schokoprinz’ retains good vigour and colour, although the foliage can become greener in stronger sunlight. It prefers fertile, moisture-retentive soil and is happiest in partial shade, though it will tolerate sun where the ground does not dry out.
