General Culture:
Easily grown in average, medium, well-drained soils in full sun to part shade. Plants of this species are noted for their shade tolerance, however too much shade decreases flower production. Prefers rich, loamy, acidic soils. Mulch roots in winter. Top growth is not reliably winter hardy throughout USDA Zone 5 where plants may suffer tip dieback or die entirely to the ground in harsh winters. When plants die to the ground in winter, the roots often survive and send up new shoots in spring.
Noteworthy Characteristics:
This tutsan cultivar is a stoloniferous, deciduous shrub which typically grows 1.5-3' tall. Best ornamental features are: (1) oval to oblong, dark plum-purplish green leaves (to 4" long) which emit a mildly resinous scent when bruised, (2) clusters of rose-like, 5-petaled, yellow flowers (3/4" diameter) with bushy center clumps of yellow stamens in summer and (3) red-aging-to-black berries in fall. Stems are distinctively 2-edged. Tutsan comes from the French words "tout" (meaning all) and "sain" (meaning healthy) in reference to various old medicinal uses for species plants, particularly the roots. This cultivar is synonymous with and sometimes also sold as 'Tedbury Purple'.
Problems:
Wilt and root rot can be significant problems, particularly in hot and humid climates of the South. Susceptible to nematodes which can cause root rot. Leaf spot, mildew and rust are less threatening.
Uses:
Low hedge or edger. Tall ground cover. Wood margins, slopes, wild gardens and naturalized areas.
