美国多年生植物协会 Perennial Plant Association – 专门服务于草本多年生植物产业

机构性质与法律地位

美国多年生植物协会（Perennial Plant Association，简称 PPA）成立于 1984 年 8 月 29 日，是在美国俄亥俄州注册的非营利性贸易协会，专门服务于草本多年生植物产业。该协会的成员由种植者、零售商、景观设计师与承包商、教育工作者以及所有专业从事多年生植物行业的人士组成，总部现设于北卡罗来纳州罗利市。

历史沿革

协会的雏形可追溯至 1983 年俄亥俄州立大学景观园艺学教授 Steven Still 博士发起的一次长期研讨会，被认为是北美首次专门讨论多年生植物的专业会议。这一会议直接促成了 PPA 在次年的正式注册成立，并奠定了其作为行业自治组织的法律基础与运作框架。

会员结构与七大地区分会

PPA 采用由七位区域董事组成的董事会进行治理，会员按业务所在地分为 7 大地区分会，分别是 Central、Western、Great Lakes、Mid-Atlantic、Northeast、Southern 六个美国地区，以及覆盖全加拿大的 Canada 地区。这一区域结构使协会能够同时覆盖北美主要的多年生植物产销市场。

Perennial Plant of the Year® 年度评选

自 1990 年起，PPA 每年由会员投票评选出一项 Perennial Plant of the Year®（年度多年生植物），评选标准要求候选植物能适应多种气候条件、低维护、相对抗病虫害、当年即可供应并具备多季节观赏价值。2026 年度评选结果是’Andropogon gerardii Blackhawks’（’黑鹰’大须芒草），近年获选品种还包括 2024 年 Phlox paniculata ‘Jeana’ 和 2023 年 Rudbeckia ‘American Gold Rush’。

教育资源与行业活动

除年度植物评选外，协会还颁发多项特别荣誉奖（Special Recognition Awards），并自 1992 年起主办 Landscape Design Awards 项目，表彰在多年生植物景观设计与施工方面的杰出作品。教育资源方面，PPA 每年夏季在不同城市举办 National Symposium 国家研讨会，并通过 PPA: Virtual Edition 系列网络研讨会与 6 月 Perennial Garden Month 持续推动行业知识传播。

Legal Status and Membership

The Perennial Plant Association (PPA) is a non-profit trade association incorporated on August 29, 1984, in the State of Ohio, dedicated to the herbaceous perennial industry. Its membership comprises growers, retailers, landscape designers and contractors, educators, and others professionally involved in the perennial trade, with operational headquarters in Raleigh, North Carolina.

Origins and Founding History

The Association traces its origins to a 1983 long-range planning symposium convened by Dr. Steven Still, Professor of Landscape Horticulture at The Ohio State University, which is widely credited as the first North American conference devoted specifically to herbaceous perennials. That gathering directly led to PPA’s formal incorporation the following year and shaped the Association’s bylaws, regional structure, and ongoing mission.

Regional Structure and the Seven Geographic Divisions

PPA is governed by a Board of Directors composed of four officers and seven regional directors, with each director representing one of seven geographic regions: Central, Western, Great Lakes, Mid-Atlantic, Northeast, Southern (covering the United States), and Canada. This regional structure, formally codified in the Association’s Bylaws, ensures representation across the major North American perennial-producing and -consuming markets.

The Perennial Plant of the Year® Program

Since 1990, PPA members have annually elected a Perennial Plant of the Year® from nominations submitted by members and trial gardens, with selection criteria emphasizing adaptability across multiple climates, low maintenance, relative pest and disease resistance, ready market availability, and multi-season ornamental interest. The 2026 selection is Andropogon gerardii ‘Blackhawks’ PP27949; recent honorees include Phlox paniculata ‘Jeana’ (2024) and Rudbeckia ‘American Gold Rush’ PP28498 (2023).

Awards, Symposia, and Educational Outreach

Beyond the annual plant selection, the Association administers a suite of Special Recognition Awards honoring industry leadership, professional service, and education, and has since 1992 operated the Landscape Design Awards program recognizing exemplary projects that feature herbaceous perennials. Educational programming includes the annual National Symposium held in different U.S. and Canadian cities each summer, the PPA: Virtual Edition webinar series, and the June Perennial Garden Month consumer outreach campaign.
