The May 2013 meeting of The National Capital Area Chapter of The Gesneriad Society will focus on artistic design entries in a gesneriad show. The meeting will be held at the U.S. National Arboretum in Washington, DC, starting at approximately 10:00 a.m.
There are several classes in a gesneriad show dedicated to artistic designs, and you can see the class descriptions in the 2013 Convention Show Schedule (direct link to PDF).
Here's an example from the 2009 Convention. Class 56 (Arrangements of Fresh Cut Gesneriad Material) was entitled "Kite Festival" and the description stated: "Whether flown singly or in tandem, the multishaped fliers attract attention with their swooping and soaring. Your interpretation in a mobile design. Niche size: 24"H x 16"W x 12"D." This particular entry was by Judy Zinni and contains the following plant material: Saintpaulia 'Blue Mist'; Columnea 'Nelly'; Seemannia 'Chic'; Columnea microphylla; Columnea hirta 'Light Prince' (dried calyces); Nematanthus fluminensis (dried, contrived form)
