协会概况与历史沿革
Svenska Rhododendronsällskapet（简称 SRS）于 1970 年在瑞典成立，宗旨是增加公众对杜鹃花的兴趣与了解，覆盖栽培、生态、植物地理、共生植物与园艺史等方向。协会同时是 Fritidsodlingens Riksorganisation（瑞典休闲园艺全国联合会）的成员组织。协会每年发行会刊《Rhododendronbladet》四期，举办年度大会、园艺市场、种子交换、摄影比赛与公开花园参观等活动，并在瑞典西、东两个地区设有分会。协会日常工作由约 10 人组成的理事会及两位候补理事执行。
组织架构与两个地方分会
协会现任理事会成员包括主席 Johan Bonde、副主席 Torsten Karlsson、财务 Carl-Magnus Pettersson、秘书 Johan Weden，理事 Carina Lind、Kerstin Pettersson 与候补理事 Johan Mattsson，以及由 Lotta Tapper 与 Göran Bergh 组成的选举委员会。协会下设两个分会：西分会 Västsvenska 冬季例会固定在 Göteborgs botaniska trädgård（哥德堡植物园）举行，每年四月在 Tjörn（特约恩）岛举办杜鹃花市场，会员来自 Halland 与 Västra Götaland 大部；东分会 Östsvenska 目前没有固定例会地点，每次活动前另行通知。按章程 § 12 与 § 13，年度大会须在每年六月底前召开，会址由理事会在各分会间轮换选定。
会刊《Rhododendronbladet》与种子交换
协会会刊《Rhododendronbladet》每年发行四期，内容涵盖物种与杂交种的专题文章、出游报告以及来自美国、斯堪的纳维亚姊妹协会的交流稿件。每年 11 至 12 月发布的 Frölistan（种子清单）是协会最受会员欢迎的活动之一，会员可申请列表中的物种与会员杂交种子；清单上常标 OP（开放授粉）、CP（控制授粉）、HP（人工授粉）、CW（野外采集）等缩写。协会与 SyRMS 合作扩充清单内容。每年四月在 Tjörn 举办的杜鹃花市场由 Lussemötet 筹备会选定品种，2022 年市场备货约 50 个品种共 300 株，分别来自德国 Hobbie 与 Schnupper Baumschule 两家苗圃。Nordiska trädgårdar（北欧园艺展）是协会每年参会的合作展览。
杜鹃花栽培知识与系统学
协会维护的栽培指南由资深种植者 Tommy Johansson 等多位会员撰写，内容涵盖场地选择、pH 4.5–5.5 的酸性基质、堆肥配置与根部保湿；指南另附 Lars-Olof Tunbrå 撰写的基质专文与 Bernt Nilsson 在 Halmstad 的 blötbädd（湿床）案例。系统学专栏由 Roberto Lesti 主笔：Davidian 1980 年代所著《The Rhododendron Species》收录约 1000 种，Pocket Guide to Rhododendron Species（McQuire 与 Robinson, 2009）将之归为 elepidota、azalea、lepidota 三大群；Cox 兄弟的《The Encyclopedia of Rhododendron Species》进一步把种类数目减至约一半，瑞典条件下约 200 种可户外栽培。协会也整理了 SKUD 列出的 32 个杂交组，包括 Yakushimanum-、Wardii-、Williamsianum-、Fortunei-、Japanska Azalea- 等。
国际合作与会员服务
协会与美国杜鹃花协会（American Rhododendron Society, ARS）保持长期合作，会员加入 SRS 后可以折扣价加入 ARS，并获取 ARS 期刊、种子交换与数字化讲座。瑞典本地会员年费为 220 SEK，加分会费 50 SEK；境外居住的会员另加 100 SEK 以补贴《Rhododendronbladet》海外邮资，会费汇入协会邮政汇票账户 PG 62 83 00-6。会员可参加摄影比赛、公开花园参观、地区例会、园艺市场与年度大会。会员事务由 Medlemsansvarig Kerstin Pettersson 负责，相关事务通过 Medlemssidan 联系页面办理。
Organisation Profile and History
Svenska Rhododendronsällskapet (SRS) was founded in 1970 with the aim of spreading interest and knowledge about rhododendrons — covering cultivation, ecology, plant geography, companion planting and horticultural history. SRS is a member of Fritidsodlingens Riksorganisation, the Swedish national federation for leisure gardening. The society publishes the quarterly journal Rhododanderbladet, runs the annual seed exchange, organises a rhododendron market in spring and coordinates photography competitions and open-garden visits. Day-to-day work is carried out by a board of about ten trustees plus two deputies.
Board and Two Regional Chapters
The current board comprises Johan Bonde (chair), Torsten Karlsson (vice-chair), Carl-Magnus Pettersson (treasurer), Johan Weden (secretary), Carina Lind and Kerstin Pettersson as ordinary members, and Johan Mattsson as deputy. Lotta Tapper and Göran Bergh form the nomination committee. The society runs two regional chapters: Västsvenska (West) meets during winter at the Botanical Institute of Göteborgs botaniska trädgård (Gothenburg Botanical Garden) and hosts the annual market on the island of Tjörn in April, drawing members from Halland and most of Västra Götaland; Östsvenska (East) currently has no fixed venue and announces each event individually. According to the statutes § 12 and § 13, the annual general meeting must be held before the end of June and the venue is rotated between chapter regions.
Journal Rhododendronbladet and Seed Exchange
Rhododendronbladet appears four times a year and features species articles, hybrid profiles, travel reports and contributions from sister societies in the United States and Scandinavia. The Frölistan (seed list) is released each November–December; members may order as many taxa as they wish, with abbreviations OP (open-pollinated), CP (controlled), HP (hand-pollinated) and CW (collected in the wild) marking the origin of each lot. SRS works with SyRMS to widen the offering. The spring market on Tjörn is prepared at Lussemötet, where the list of cultivars is finalised; the 2022 market offered around 50 cultivars and roughly 300 plants sourced from the German nurseries Hobbie and Schnupper Baumschule. SRS also takes part in Nordiska trädgårdar, the Nordic garden fair.
Cultivation Knowledge and Taxonomy
The cultivation pages on the website are based on notes from experienced growers such as Tommy Johansson, covering site selection, acidic substrates with pH 4.5–5.5, compost recipes and root-zone moisture, supplemented by Lars-Olof Tunbrå on substrate chemistry and Bernt Nilsson’s blötbädd (wet bed) construction at Halmstad. Roberto Lesti maintains the taxonomy section: Davidian’s 1980s work The Rhododendron Species listed around 1,000 species, McQuire & Robinson’s Pocket Guide to Rhododendron Species (2009) grouped them into elepidota, azalea and lepidota divisions, and Peter and Kenneth Cox’s Encyclopedia of Rhododendron Species reduced the total to roughly half, with around 200 considered outdoor-hardy in Sweden. The site also lists 32 hybrid groups recorded by SKUD, including Yakushimanum, Wardii, Williamsianum, Fortunei and Japanska Azalea.
International Cooperation and Member Services
SRS maintains a long-standing partnership with the American Rhododendron Society (ARS): members can join ARS at a discounted rate and receive its journal, seed exchange and digital lectures. Annual membership fees are 220 SEK plus 50 SEK per chapter; members living outside Sweden pay an additional 100 SEK to cover overseas postage of Rhododendronbladet. Fees are paid into the society’s postal giro account PG 62 83 00-6. Membership benefits include access to the photography competition, open-garden visits, regional meetings, the spring market and the annual general meeting. Member services are handled by Medlemsansvarig Kerstin Pettersson and processed through the Medlemssidan (members’ page).
