Abelias have been part of the garden our entire married life (now 44 years). In Urbana, IL, a dieback shrub yet back to 3’ high and wide with flowers in late summer-fall. Typically a 3 to 6’ high deciduous (north) to often semi-evergreen (south) shrub, but at Keith Arboretum, Chapel Hill, NC, a 70-year-old plant was 18’ by 20’. Without question, plants do not read books when it comes to size. Many growers and gardeners were tired of the old, creaky, green leaf, everyday A. ×grandiflora. With 70 years under my belt, much has changed, and for the better.

 

Nursery growers, retailers, and gardeners have numerous superior choices. Variegated foliage is the current rage and bronze, ruby, red, orange, cream, yellow, and green permutations are available. Breeders and selectors have elevated (my belief) this antiquarian garden species to modern day respectability and interest.

 

Many of the cultivars are described in the Dirr Manual, 2009, Dirr Encyclopedia 2011, and can be sourced therein. For the newest cultivars a brief synopsis is presented. Patent numbers are listed and the reader seeking complete history and profiles can visit uspto.gov. I read all the patented Abelia descriptions and, to be clear, there is ambiguity relative to exact parentage.

 

Kelli and I thought this Checklist concept would serve as a portal for the exchange of timely, useful information. An example is the borderline insane rebranding/renaming of an existing/older cultivar that was not protected. ‘Hopley’s (‘Aghop’), a pretty variegated cultivar from England, with PBR in Europe, was not protected in the United States. So ‘Hopley’s’ = Twist of Lime™ in Garden Debut® = Lemon Zest™ in Southern Living Plant Collection, 2014. Perfectly legitimate, but confusing to growers and consumers.

Additional introductions are in the evaluation pipeline. Dr. Carol Robacker, University of Georgia, has at least five. They are described in Nursery Management at http://www.nurserymag.com/nursery-1210-new-use-abelias.aspx?List_id=6&email=%255B~email~%255D&key=%255B~key~%255D

 

At Plant Introductions, Inc., Abelia parvifolia, ‘Rose Creek’, Eternal Sunshine™, and Kaleidoscope™ seedlings are being evaluated along with several variegated (green/white, compact habit) sports. In September 2013, at Nova Flora/Conard-Pyle and Green Leaf-Aris Horticulture Inc., PA, I observed Abelia trials with only breeder coded (#) accessions. Nothing overwhelmed!

 

Abelia umbrellas ~30 species with a new white-flowered taxon reported from Japan. Seismic taxonomic upheavals portend major revisions in the genus. Work at Kew Gardens, England, suggests four genera, Abelia, Diabelia, Vesalea, and Zabelia, will be delineated from the current Abelia. The origin of A. ×grandiflora, A. chinensis × A. uniflora, was shrouded in a taxonomic fog. What is A. uniflora? Although in plain view, most horticulturists had no concept. Appears A. uniflora is the correct taxonomic home for A. shumannii, A. engleriana, A. macrotera, and A. parvifolia.

 

Nursery Management invites your constructive thoughts for improvement and will update the information on a timely basis. Checklists of other prominent ornamental taxa like Loropetalum, Hydrangea, and Spiraea will be forthcoming.

A rename. See ‘Margarita’. Note how descriptions do not jibe. Have observed the plant and wonder how two seemingly disparate descriptions can evolve. Such is marketing.

Epilogue: Four additional names surfaced: ‘Little Gem’, ‘Short and Sweet’ (like ‘Compacta’), ‘Snowdrift’, and ‘Mei-fu-hana-tsukubane-utsugi’ (variegated). None have crossed my path.

 

The AGM refers to Award of Garden Merit given by The Royal Horticultural Society, England. The Abelia trial was conducted from 2004 to 2009. Criteria for the award are:

·       Excellent for ordinary garden use

·       Available

·       Reasonably resistant to pests

·       Of good constitution

·       Essentially stable in form and color

·       Reasonably easy to grow

 

Worth noting that two of my unpatented Georgia introductions, ‘Canyon Creek’ and ‘Rose Creek’, both named by Mark Griffith, received this noteworthy designation. Do AGM’s help to sell plants? I don’t know! They do provide a measure of confidence for the consumer.
