网络上的铁线莲 Clematis on the Web – 欧洲铁线莲品种数据库

数据库概况

网络上的铁线莲（Clematis on the Web）是一个面向全球铁线莲爱好者的线上资料库，1999 年由英国人 Richard Green 与 Ian Lang 共同创建，2023 年 1 月起由国际铁线莲协会（International Clematis Society）接手维护与开发。站点长期收集来自多方的铁线莲资料，配合英国皇家园艺学会（RHS）建议的命名规则——RHS 也是目前铁线莲品种的国际登录机构——让数据在植物分类与商用园艺两个层面都对得上号。

收录规模与数据来源

目前数据库收录超过 4000 个铁线莲品种，并配了 4000 多张照片，覆盖其中一半多的品种。网站内容最初靠创始人数十年的手工录入与对照而来，文字资料主要取自：国际铁线莲协会会刊《Clematis International》、英国铁线莲协会会刊《The Clematis》、Magnus Johnson 的两本专著《Slaktet Klematis》与《The genus Clematis》、Christopher Grey-Wilson 的《Clematis, the Genus》、Timber Press 出版的《An Illustrated Encyclopedia of Clematis》、RHS 在 2002 年出版的《International Clematis Register and Checklist》及后续补充本、RHS Plant Finder 1999-2000 年版。

检索与浏览功能

网站提供几种互补的检索入口：按品种名或关键词做文字检索（Text search）、按花型花色做图片检索（Picture search）、按字母顺序浏览全库的 A–Z 目录，以及单独的「Clematis people」人物志，列出历史上的育种家、摄影作者、研究者与各时期协会的活跃成员。「Pruning」与「Diseases」两个专题页是铁线莲栽培养护的常用工具，分别按修剪组（Group 1/2/3）和常见病害讲解，把品种数据与栽培知识串成一套完整的使用手册。

照片与维护团队

数据库里的大量照片出自固定合作的铁线莲苗圃与个人爱好者。贡献者名单很长，包括 J van Zoest（荷兰 Boskoop 铁线莲专业苗圃）、Kivistik 家族（爱沙尼亚 Roogoja 农场）、Thorncroft Clematis Nursery、Silver Star Vinery、Raymond Evison、Bremer Clematis Gardens、Ton Hannink 等机构与育种者，他们长期向数据库输送品种照片与新条目；国际铁线莲登记员（Duncan Donald、Victoria Matthews）也协助审核名称与登录信息。2023 年起，主编改由 Agnes Kwan 等协会志愿者接手，原创办人继续保留顾问身份。

与其他网站的区别

与其他商业苗圃网站不同，Clematis on the Web 不卖苗、不代为鉴定照片来源，也不提供园艺建议；导航条上的「Contact Us」主要是供使用者提交勘误、新条目与新照片。站点本身是英文为主，但品种名称按 RHS 国际登录的拉丁学名书写，世界各地的铁线莲爱好者都能检索。整站自 1999 年上线以来一直免费开放，版权声明 1999–2026 表明它是个长期持续更新的资源库。

About the Database

Clematis on the Web is an online reference database aimed at clematis enthusiasts worldwide. It was set up in 1999 by Richard Green and Ian Lang in the UK, and from January 2023 has been maintained and developed under the umbrella of the International Clematis Society. The site follows the naming conventions recommended by the Royal Horticultural Society, the present International Cultivar Registration Authority for clematis, so the cultivar names you find here align with those used in horticultural trade and in formal registration.

Scope and Sources

The database currently covers more than four thousand clematis cultivars, illustrated by over four thousand photographs that depict well over half of the entries. The text content was assembled over many years from a wide range of sources, the most important of which are: the journal Clematis International of the International Clematis Society; the journal The Clematis of the British Clematis Society; Magnus Johnson’s Slaktet Klematis and The Genus Clematis; Christopher Grey-Wilson’s monograph Clematis, the Genus; Toomey and Leeds’s An Illustrated Encyclopedia of Clematis; the RHS publication International Clematis Register and Checklist 2002 and its periodic supplements; and the RHS Plant Finder 1999–2000 edition.

Search and Browse Features

The site offers several complementary ways in. There is a full-text search by cultivar name or keyword, a picture search that lets you narrow down by flower shape and colour, an A–Z index of the whole collection, and a separate “Clematis people” section listing breeders, photographers, researchers and active members of the various societies through the years. The “Pruning” and “Diseases” pages turn the variety database into a working handbook: pruning is explained by clematis pruning group (Group 1 / 2 / 3), while the diseases pages cover the most common ailments you are likely to encounter in cultivation.

Photographs and the People Behind the Site

A large share of the photographs in the database comes from a fairly fixed circle of contributing nurseries and individuals. The acknowledgements list runs to several dozen names and includes major clematis breeders and collectors — J van Zoest in Boskoop, the Kivistik family at Roogoja in Estonia, Thorncroft Clematis Nursery, Silver Star Vinery, Raymond Evison, Bremer Clematis Gardens, Ton Hannink and many others — who have fed the database with new cultivars and new pictures over the years. The International Clematis Registrars (Duncan Donald, Victoria Matthews) have also helped review names and registration details. Since 2023 the editorship has been carried by Agnes Kwan and other ICS volunteers, while the original founders retain an advisory role.

What the Site Is Not

Unlike a commercial clematis nursery, Clematis on the Web does not sell plants, does not identify unnamed photographs from emails, and does not offer general gardening advice: the “Contact Us” link in the top menu exists mainly to collect corrections, new entries and new photographs from contributors. The site itself is in English, but the cultivar names follow the Latin nomenclature registered with the RHS, which means anyone in the world who knows the official spelling can find a particular plant. The site has been freely available online since 1999, and the copyright notice 1999–2026 reflects the long-running nature of the project.
