英国大丽花协会 National Dahlia Society – 英国历史最久规模最大的大丽花专业团体

协会历史与宗旨

英国大丽花协会（National Dahlia Society, NDS）成立于 1881 年，是英国历史最久、规模最大的全大丽花专业团体。协会以注册慈善机构身份运作（Registered Charity No: 254049），长期通过花展、品种试验和会议推广大丽花栽培，每年固定在 RHS Wisley 花园与 Harrogate 大约克郡展览场举办主要展会，参会会员享有入场优惠。

会员服务与出版物

协会每年向会员发放两期主要出版物：冬季的 Winter Bulletin 与夏季刊 The Dahlia Annual，内容涵盖栽培、试验、品种选择与赛事报道。新会员入会即赠 Classified Directory（推荐品种分类目录）以及 Ted Collins 著《Dahlias for You》。协会另设专属信息咨询渠道，帮助会员解决栽种难题，并在威尔士、苏格兰、爱尔兰指定联络代表。

大丽花分类与品种研究

协会对大丽花品种的分类研究面向全球公开。单瓣、Anemone、Collerette、Waterlily、Decorative、Ball、Pompon、Cactus、Semi-cactus、Stellar 等十多个分组各有形态标准；花卉源自墨西哥，最初由 Dahlia pinnata、Dahlia rosea 与 Dahlia coccinea 三个原种引入欧洲，第一份双瓣品种在十九世纪中期由 Show 与 Fancy 两类定型，1872 年 Juarrezii 经乌得勒支传入后才逐步形成 Cactus 与 Decorative 两大现代分支。

全国展会与裁判体系

协会每年春季在全国各地举办日间会议，并组织裁判考试，2024 年度的裁判考试已于 RHS Wisley 举行。协会的国家大丽花展（Wisley）与北方大丽花展（Harrogate）面向所有下属团体及独立参展者开放，分类目录每年根据品种重新分类整理，是裁判评分与栽培选种的官方依据。

下属团体与对外联络

协会在英国及国际范围与多个大丽花团体保持联系，下属团体可冠名使用 NDS 奖牌，亦可在 NDS 出版物上刊登宣传材料。会员入会需通过协会官方主页的「How to Join」页面提交申请，并选定相应的个人或家庭会员方案。

History and Purpose

The National Dahlia Society (NDS) was formed in 1881, making it one of the longest-established all-dahlia societies in the world. Operating as a registered charity (Registered Charity No: 254049), the society promotes dahlia cultivation through exhibitions, trials and conferences, with its two main annual shows held at RHS Wisley and the Great Yorkshire Showground in Harrogate, both offering reduced admission for members.

Member Services and Publications

Members receive two publications each year: the Winter Bulletin and the summer Dahlia Annual, which cover cultivation, trials, shows and cultivar selection. New members are sent a complimentary Classified Directory of recommended cultivars together with a copy of Ted Collins’ book ‘Dahlias for You’. The society also runs an information service that puts members in touch with regional representatives in Wales, Scotland and Ireland.

Dahlia Classification and Cultivar Research

The society publishes a comprehensive classification of dahlia types covering Single, Anemone, Collerette, Waterlily, Decorative, Ball, Pompom, Cactus, Semi-cactus, Stellar and other groups, with each group defined by floret shape and arrangement. The flower originated in Mexico: Dahlia pinnata, Dahlia rosea and Dahlia coccinea were the first named species introduced to Europe, with double Show and Fancy forms appearing in the mid-1800s, followed by Anemone forms in 1829, Pompons in 1850, and the Cactus and Decorative types after the arrival of ‘Juarrezii’ in Holland in 1872.

National Shows and Judging System

Conferences are held annually around the country in March, and judging examinations are run by the society to maintain its list of qualified judges. The NDS National Show at Wisley and the Northern Show at Harrogate are open to affiliated societies and independent exhibitors, with the Classified Directory serving as the official reference for judging and cultivar registration.

Affiliated Societies and External Links

The NDS links with dahlia societies across the UK and abroad. Affiliated societies may enter inter-society classes at the National Shows and award NDS medals at their own events, and are listed in NDS publications. New members can apply through the ‘How to Join’ page on the official website and choose an individual or family membership plan.
