  • Broadleaf deciduous shrub, upright, 8 ft tall and wide (2.4 m), but may reach 15 × 10 ft (4.5 × 3 m).  Leaves opposite, simple, 12-18 cm long, 5-7 vein pairs, base asymmetrical, margin with occasional and irregular teeth, glossy, bright green, pubescence on veins below.  Flowers maroon wine-colored, 7.5 cm wide, creamy-white tipped stamens, blooms from spring through early summer, weakly fragrant.  The flowers are sterile so the plant does not produce seed.
  • Sun or part shade.
  • Hardy to USDA Zone (5) 6        Richard Hartlage, then an undergraduate at North Carolina State University, performed a series of reciprocal crosses between Sinocalycanthus chinensis (Chinese Sweetshrub or Wax Plant) and Calycanthus floridus (Carolina Allspice or Sweetshrub) to produce what was considered a new bigeneric hybrid that was later named ×Sinocalycalycanthus raulstonii ‘Hartlage Wine’ (HortSciece 36(4):765-767. 2001), but see below.
  • Sinocalycanthus chinensis is closely related to Calycanthus and recently some authorities have classified it as a Calycanthus, hence named Calycanthus chinensis.   In this view then, the name for the hybrid should be Calycanthus × raulstonii ‘Hartlage Wine’.
  • raulstonii: to honor J.C. Raulston, Director of the North Carolina State Univ. Arboretum (subsequently renamed the JC Raulston Arboretum), he directed the hybridization before his death in 1996.
