Origin & Breeding History: 'SMVDBL' was bred and developed by the breeder, Timothy D. Wood, at Spring Meadow Nursery, Inc. in Grand Haven, Michigan, USA. It originated from an open pollination that occurred in the summer of 2007 between an unnamed seedling of Viburnum dentatum var. deamii as the female parent and an unnamed seedling as the male parent. 'SMVDBL' was selected from the resulting progeny in the spring of 2009 based on its plant growth habit, glossy foliage, attractive dense flower heads, attractive fruit and good production characteristics. Vegetative reproduction of 'SMVDBL' was first conducted by softwood cuttings in June of 2009 in Grand Haven, Michigan, USA.

Tests & Trials: The comparative trial of 'SMVDBL' was conducted as an outdoor container trial in the spring of 2015 at BioFlora Inc. in St. Thomas, Ontario. It included a total of 10 plants each of the candidate and reference varieties. All plants were grown from rooted cuttings transplanted into 13 litre containers in 2013. The plants were overwintered in a polyhouse for two winters. The trial was arranged in rows outdoors with 1 metre spacing between plants. Observations and measurements were taken from 10 plants or parts of plants of each variety on June 8-9, 2015. All colour determinations were made using the 2007 Royal Horticultural Society (RHS) Colour Chart.
