历史沿革与园区规模
萨默兰观赏花园（The Summerland Ornamental Gardens）位于加拿大不列颠哥伦比亚省（BC 省）南奥肯那根山谷萨默兰镇，确切地址为 4200 Highway #97 South, Summerland, BC。花园占地约 15 英亩（6 公顷），以英式花园为蓝本设计，由 Joseph Smith 与 Alfred Aveson 两位园艺师于 1916 年参照 Wedgewood 瓷盘的英式花园图样完成平面规划，至今已有 110 年历史。花园隶属于联邦农业及农业食品部（Agriculture and Agri-Food Canada, AAFC）下辖的 Summerland Research and Development Centre，于 1914 年作为 Dominion Experimental Farm 的组成部分正式建立，1916 年起由农业部直接管辖并对外开放。1991 年，AAFC 退出园艺研究项目后，由新成立的萨默兰观赏花园之友协会（Friends of the Summerland Ornamental Gardens Society, 简称 FOG）接手日常维护与运营，目前通过 AAFC 颁发的占用许可证持有花园土地使用权，但并不接受联邦政府直接拨款。
主要园区与景观主题
萨默兰观赏花园按主题划分了多个示范园区，涵盖示范花园、节水示范花园（Xeriscape Demonstration Garden）、仙人掌花园、鸢尾园、草地园、蝴蝶园、遮阳花园以及多年生花卉与一年生花卉轮作区等主题展区。花园在 2023/24 年冬季遭遇极端气候事件，2024 年 1 月 11 日至 12 日气温从 1°C 在 48 小时内骤降至 −26.2°C，配合 40-60 km/h 的北风，对玫瑰花圃中的 Hybrid Tea 与 Floribunda 品种造成严重冻害，园方已对不耐寒品种在根部培覆木屑保护。玫瑰园历史可追溯至 1916 年建园初期，园中保留的早期天竺葵、大丽花与多年生花卉曾在全国园艺展览中获得认可。
本土植物与耐寒研究
萨默兰观赏花园在节水示范花园内与美国奥肯那根 Xeriscape 协会（Okanagan Xeriscape Association）合作，专门展示适宜奥肯那根干旱气候的本土与耐旱植物。Summerland Secondary School 学生 Ashley Tiessen 协助园方在节水花园中为 Syilx Okanagan 族原住民传统利用的本土植物标牌注明 Nsyilxen（Okanagan 语）学名与发音，以便游客学习本土植物知识。园区还设有 John Waddington 多年生植物耐寒试验区，专门测试从美国西部引种的多年生植物在 BC 省冬季气候下的表现，为奥肯那根山谷的居民筛选适合干燥气候的观赏植物。
会员机制与公众活动
萨默兰观赏花园实行会员制与志愿者运营模式，会员费、植物义卖、捐款、申请政府与基金会拨款（如 Amethyst Foundation、TD Friends of the Environment Foundation、District of Summerland、Gaming BC、Okanagan Basin Water Board 等）是 FOG 协会的主要资金来源。园内雇用 2 名专职园丁负责日常维护，其余工作由 8 支志愿者团队承担，每队设队长，分别负责示范园、玫瑰园、节水花园、遮阳花园、菜园灌溉、活动筹办、通讯与筹款、植物义卖等专项工作。花园全年免费对公众开放（建议捐款 5 加元/人），每年春季与秋季各举办一次植物义卖（Plant Sale），夏季举办两场艺术与音乐活动，冬季根据天气状况限时开放。开放时间为：春季 3 月 15 日至维多利亚日 8:00-18:00；夏季维多利亚日至劳动节 8:00-20:00；秋季劳动节至 11 月第一个星期日 8:00-18:00；冬季 11 月第一个星期日至次年 3 月第二个星期日 8:00-16:00（视天气而定）。
组织治理与可持续使命
萨默兰观赏花园之友协会（FOG）成立于 1991 年，宗旨为”保护、维护并美化这座历史花园，为社区提供可持续园艺实践的乐趣与教育源泉”（preserve, maintain and enhance the beauty of the historic gardens, offering the community a source of enjoyment and education in sustainable gardening practices）。FOG 协会由 2024 年度董事会成员 Bonnie Fulton（主席）、Kenna MacKenzie（副主席）、Louisa Carter（财务）、Helen Lawrence（秘书）、Connie Davis（志愿者与会员总监）、Melanie Reichle（园艺总监）、Ken Roberge、Scott Austin、Marcia Lucertini 等 9 名董事共同治理。协会重点关注水资源保护与本土传粉昆虫栖息地建设两大议题，并与边境无蜂（Border Free Bees）、奥肯那根节水协会（Okanagan Xeriscape Association）、Dogwood Nursery、Sagebrush Nursery、XEN West Kelowna 等社区合作伙伴保持长期协作。
History and Site Scale
The Summerland Ornamental Gardens are situated at 4200 Highway #97 South, Summerland, in the South Okanagan Valley of British Columbia, Canada. The 6-hectare (15-acre) historic gardens were designed in the English landscape tradition: in 1916, staff gardeners Joseph Smith and Alfred Aveson sketched out the original garden plan based on an English garden scene depicted on a Wedgwood plate. The Gardens were established in 1914 as part of the Dominion Experimental Farm, a federal agricultural research station operated by Agriculture and Agri-Food Canada (AAFC). After AAFC phased out its horticulture program in 1991, the Friends of the Summerland Ornamental Gardens Society (FOG) was incorporated to maintain the Gardens under a Licence of Occupation granted by AAFC, with in-kind support from the Summerland Research and Development Centre.
Garden Collection and Landscape Themes
The Summerland Ornamental Gardens comprise several demonstration areas, including display gardens, a Xeriscape Demonstration Garden, a cactus garden, an iris garden, meadow plantings, a butterfly garden, shade gardens, and extensive perennial and annual flower beds. The Rose Garden is one of the oldest collections, established alongside the 1916 founding plantings; geraniums, hollyhocks, dahlias and drought-tolerant perennials flourished in the original beds. During the January 2024 polar vortex event, overnight temperatures plunged from 1°C to −26.2°C in less than 48 hours, with north winds gusting to 40–60 km/h, causing severe winter damage to Hybrid Tea and Floribunda roses. The Gardens now mound less-hardy varieties with wood chips each fall to protect more cane in future cold snaps.
Native Plants and Hardiness Research
In collaboration with the Okanagan Xeriscape Association and community partners such as Dogwood Nursery, Sagebrush Nursery and XEN West Kelowna, the Gardens maintain a Xeriscape Demonstration Garden featuring drought-tolerant and native plants adapted to the dry Okanagan climate. Summerland Secondary School student Ashley Tiessen, working with Taylor Lezard, has labelled native plants in the Xeriscape Garden with both the Latin binomial and the Nsyilxen (Okanagan language) name used by the Syilx Okanagan people, with audio recordings of the pronunciations available online. The Gardens also host the John Waddington perennial hardiness trial beds, evaluating plant material from the western United States for suitability to South Okanagan winter conditions; findings from this long-running research continue to inform home gardeners across the region.
Membership and Public Engagement
The Gardens are operated by FOG through a hybrid model of two paid gardeners and eight volunteer teams. Memberships, donations, plant sales, and grants-in-aid from funders including the Amethyst Foundation, District of Summerland, Gaming BC, Okanagan Basin Water Board, and TD Friends of the Environment Foundation sustain operations. Admission is by donation (suggested $5 per person); the Gardens are unable to reserve space for weddings or private group functions. Two paid staff and approximately 50–80 active volunteers maintain the 6 hectares of flowers, shrubs, and trees. Public events include the spring and fall Plant Sales, two annual Art and Music events, off-site garden tours twice a year, and seasonal workshops. Seasonal hours: Spring 8:00 am – 6:00 pm (March 15 to Victoria Day); Summer 8:00 am – 8:00 pm (Victoria Day to Labour Day); Fall 8:00 am – 6:00 pm (Labour Day to first Sunday in November); Winter 8:00 am – 4:00 pm (weather permitting, first Sunday in November to second Sunday in March).
Governance and Sustainability Mandate
The Friends of the Summerland Ornamental Gardens Society (FOG), incorporated in 1991, is governed by a volunteer board currently chaired by Bonnie Fulton, with Kenna MacKenzie as Vice-Chair, Louisa Carter as Treasurer, Helen Lawrence as Secretary, Connie Davis as Volunteer and Membership Director, Melanie Reichle as Grounds Director, and directors Ken Roberge, Scott Austin, and Marcia Lucertini. FOG’s mission is “to preserve, maintain and enhance the beauty of the historic gardens, offering the community a source of enjoyment and education in sustainable gardening practices.” Two focus areas guide the Society’s programming: water conservation in the dry Okanagan climate, and providing habitat for native pollinators. FOG partners with Agriculture Agri-Food Canada (federal partner), Border Free Bees, the Okanagan Xeriscape Association, and local businesses such as Windmill Garden Centre, Summerland and District Credit Union, Summerland Greenhouses, and True Grains Bakehouse to deliver programming across the South Okanagan.
