Patent Abstract:

Full Description:
Genus and species of plant claimed:  Viburnum  sp. L. 
     Variety denomination: ‘PIIVIB-I’. 
     BACKGROUND OF THE INVENTION 
     The present invention relates to a new and distinct cultivar of  Viburnum,  a member of the Adoxaceae family, hereinafter referred to by its cultivar name ‘PIIVIB-I’. This cultivar is grown primarily as an ornamental for landscape use. 
     The cultivar originated from an open-pollination of  Viburnum  ‘Nantucket’ (unpatented) in Watkinsville, Ga., and was selected from the progeny of this pollination by continued evaluation for compact growth habit and improved evergreen leaf and flower characteristics. 
     ‘PIIVIB-I’ has been asexually reproduced by semi-hardwood cuttings in Watkinsville, Ga. since 2006. The characteristics of the cultivar have been stable and reproduced true-to-type in successive vegetative generations. 
     SUMMARY OF THE INVENTION 
     ‘PIIVIB-I’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with changes in light, temperature, soil and rainfall without, however, any variance in genotype. 
     The following traits have been observed and represent the characteristics of the new cultivar. In combination these characteristics distinguish ‘PIIVIB-I’ from all other varieties in commerce known to the inventor. 1) Compact, mounding growth habit. 2) Small, lustrous, dark green, evergreen foliage. 3) White flowers produced in abundance even on young plants. 4) Clusters of red fruit that turn black when mature. 
     ‘PIIVIB-I’ is distinguished from its female parent ‘Nantucket’ by its growth habit and foliage. ‘PIIVIB-I’ has a compact, mounding growth habit and small, dark green, evergreen foliage that is lustrous on the upper surface and pubescent on the lower surface, whereas ‘Nantucket’ has a compact, upright growth habit and larger, semi-evergreen foliage that is pubescent on the upper and lower surfaces. There are no other cultivars of  Viburnum  with this combination of characteristics known to the inventor. 
     Plants of the new  Viburnum  can be compared to plants of the cultivar ‘Conoy’ (unpatented), although ‘PIIVIB-I’ is distinguished from ‘Conoy’ by growth habit and foliage and flower characteristics. ‘PIIVIB-I’ has a compact, mounding growth habit, small, dark green, evergreen foliage, and white flowers produced in abundance even on young plants, whereas ‘Conoy’ has a compact, irregular growth habit, smaller, slightly twisted, evergreen foliage, and less abundant, smaller inflorescences.

     DETAILED DESCRIPTION 
     In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the description were grown in 11.8 L containers in full sun under outdoor conditions in a nursery in Watkinsville, Ga.
     Botanical classification: ‘PIIVIB-I’ is a cultivar of  Viburnum.      Parentage: The current variety is a progeny from an open-pollination of  Viburnum  ‘Nantucket’.   Propagation: Vegetatively by stem cuttings.   Time to initiate roots in summer: About 5 to 6 weeks at 32° C.   Plant description: The claimed variety is a freely branching, compact, mounding evergreen shrub. The plant is hardy in USDA Zones 6 to 8.
