Erect to rounded deciduous shrub. Fragrant flowers are maroon and bloom April-July. Grows in full sun to part shade in average to rich, well drained soil. This trouble free shrub is good as speciman-, foundation-, and border plantings. Good in fresh cut arrangement. Prune after flowering to maintain shape, and manage suckers to prevent naturalization. Propagate by seed or cuttings.
 
Sweet shrub seeds can be sown in springtime (March or April) in a shady area of the garden or woods edge.  Use rich, well-drained loamy soil.  Plant seeds 1/4 inch deep and keep soil moist. Stratification for best seed germination.
