协会源起与定位
特拉华河谷蕨类植物与野花协会（Delaware Valley Fern & Wildflower Society，简称 DVFWS）成立于 1975 年，由费城地区一批喜爱本土蕨类和野花的爱好者自发组成，是一个非营利的园艺兴趣团体。协会的宗旨是带领会员走进自然，认识本土蕨类、本土野花与本土灌木的生长环境，并在野外和花园中相互学习。2026 年是协会成立 50 周年，会员们将在费城花展现场庆祝这个里程碑。
活动形式与年度节奏
协会每年举行三次正式业务会议，4 月到 10 月之间则安排多次野外考察和短途散步，走访展示本土植物与蕨类的自然保护地和私人花园。新会员主要由野外观鸟活动及费城花展招募，感兴趣者只需提交一份会费单即可加入。每年的活动主题通过会员问卷收集，并在花展的会员手册中公布。
费城花展与植物社团联合展区
DVFWS 自 1976 年起参加费城花展，至今已有 50 年历史。2026 年花展 2 月 28 日至 3 月 8 日举行，主题为 ROOTED: the Origins of American Gardening，DVFWS 共展出 30 余种蕨类，28 位志愿者在一周内承担了大部分值班任务，并向参观者售出超过 110 份《蕨类养护手册》。在植物社团联合展区，另有 8 个相关协会的 108 名志愿者共承担 183 个值班时段，共同营造了花展一角的人气。
会员、章程与对外联络
协会对所有对蕨类、本土植物与花园感兴趣的公众开放，会费为个人每年 10 美元或同一家庭两人每年 14 美元。会员除可参加野外观鸟、讲座、花展值班外，还能收到协会的季度通讯。日常事务由会长 Richard Reynolds、副会长 Leslie Morris-Smith 等骨干共同承担，会员事务由 Janet Whitefield 负责，野外考察由 David Lauer 协调。

Origins and Mission
The Delaware Valley Fern & Wildflower Society (DVFWS) was formed in 1975 by a group of native fern and wildflower enthusiasts in the greater Philadelphia area. It is a non-profit hobbyist organization devoted to exploring ferns in nature and educating members and the public about native ferns, native wildflowers, and native shrubs. The society will celebrate its 50th year with an exhibit at the 2026 Philadelphia Flower Show.
Activities and Annual Rhythm
The society holds three business meetings per year and schedules frequent field trips and short walks from April through October, visiting natural areas and gardens that showcase native plants and ferns. New members are recruited primarily at these walks and at the Philadelphia Flower Show booth; anyone with an interest in native plants may join by submitting a dues payment. Annual field trip themes are gathered through member surveys and announced in the membership flyer distributed at the Flower Show.
Philadelphia Flower Show and the Plant Society Corner
DVFWS has exhibited at the Philadelphia Flower Show since 1976, marking 50 years of continuous participation in 2026. The 2026 show ran February 28 to March 8 under the theme ROOTED: the Origins of American Gardening. DVFWS displayed over 30 different ferns and fielded 28 volunteers covering most shifts during the week, while selling more than 110 copies of its Fern Care booklets on Indoor Tropical Ferns and Hardy Native Ferns. The Plant Society corner brought together eight related societies, with 108 volunteers from those groups filling 183 booth slots.
Membership, Dues, and Officers
Membership is open to anyone interested in learning about ferns, native plants, and gardens. Annual dues are $10 for an individual or $14 for a couple in one household. Members receive the society’s quarterly newsletter and may attend lectures, field trips, and Flower Show shifts. Officers include President Richard Reynolds, Vice President Leslie Morris-Smith, Membership chair Janet Whitefield, and Field Trip Coordinator David Lauer.
Resources and External Links
The society maintains links to allied organizations such as the American Fern Society and the Hardy Fern Foundation, as well as references including the Pteridologia 3 glossary for taxonomic pteridology. Public garden listings highlight tropical and hardy fern collections worth visiting, and a separate page indexes member gardens open to fellow enthusiasts.
