Institutional HSA Certified Holly Arboretums and Test Centers
An organization recognized by the Holly Society of America as an official Holly Arboretum or Experimental Test Center is a public or semi-public institution that educates plant lovers in the use of Holly in the landscape and that complies with set HSA guidelines. Its Holly collection is properly labeled and it maintains accurate records of its Hollies so that each plant can be identified by location, valid name, source, date received, size or age when received, and other pertinent facts. Annual reports submitted by Official Holly Arboreta and Experimental Test Centers are included in the Holly Society Journal.
