Flowering Time: Oct Note: Distinct from Viburnum tinus L. based on chloroplast tree (Clement et al., 2014); reported in TJM (2012) as possibly naturalized in Tilden Park, based on plants in flower in October 2001 (Ertter 17810) that were said on collection label to be "lax" and "occasional" and observed by Rosatti in October 2014 to be lax, yet not in flower and in greater numbers than might be suggested by "occasional".
