美国 Edgewood 花园 – 宾州稀有植物专类园

位置与小生境

Edgewood 是一座私人花园, 位于美国宾夕法尼亚州东南部 Chester 县的 Exton, USDA 耐寒分区 7a, 由英国出生的植物学家 John Lonsdale 博士自 1995 年起持续维护. 园址坐落在大山谷 (Great Valley) 北侧山脊线下方, 海拔约 600 英尺, 较谷底高约 300 英尺, 朝南的避风地形和较好的排水条件让多种原本难以在当地存活的植物顺利越冬.

地形与土壤

花园占地约 1.6 英亩, 自北向南延伸 400 英尺, 坡度接近 40°, 顶部保留约一英亩的本地落叶林. 土壤呈微酸性, 富含碎石, 除车道和房前的抬升苗床 (raised beds) 外基本保留原生状态. 这些小生境为高山植物、旱生植物和球根植物提供了与原生高地相近的排水与越夏条件.

植物收藏方向

园内栽植数千种耐寒植物、乔木与灌木, 重点收藏稀有高山植物、林地植物和旱生植物, 以及各类球根. 物种涵盖 Galanthus (雪滴花) 各品种、Cyclamen (仙客来) 多种、Trillium (延龄草) 本地与外州种群、Helleborus (嚏根草) 杂交系列、稀有 Colchicum 与 Eranthis, 以及 Adonis、Spigelia、Iris dabashanensis 等区域性新引种. 收藏方向以分布在五种主要小生境——抬升苗床、旱生苗床、沼泽苗床、林地与冷凉温室——中的植物为主.

摄影存档与对外活动

过去二十多年间, 园主累积了超过 20000 张数字照片记录花园与植物变化, 影像资料在 Edgewood 主站 Image Galleries 板块按属与季节分组, 兼具史料与教学用途. 不接受一般访客到访, 但植物可通过在线订购或在春秋两季的特邀销售 (plant sales) 与公开演讲 (presentations) 现场购买, 演讲活动地点遍及宾州、北卡罗来纳州、特拉华州、罗德岛州等多地.

Location & Microhabitats

Edgewood is a private garden situated in Exton, Chester County, southeastern Pennsylvania (USDA Zone 7a), continuously developed since 1995 by British-born botanist Dr. John Lonsdale. The property sits just below the ridge-line on the northern side of the Great Valley, 600 feet above sea level and roughly 300 feet above the valley floor. Its sheltered, south-facing aspect and excellent drainage allow many plants that would not normally survive in this region to thrive.

Terrain & Soil

The garden covers about 1.6 acres, extending 400 feet with a nearly 40° slope. About one acre of native deciduous woodland occupies the upper portion, while the soil is slightly acidic and rocky across the rest of the site. Only the raised beds along the driveway and the house are improved; the remainder is left in its natural state. These conditions mimic upland habitats, favouring alpines, xeric plants, and bulbs.

Plant Collections

Several thousand hardy plants, trees and shrubs are cultivated here, with a focus on rare alpines, woodland species, xeric plants, and specialty bulbs. Noted genera include Galanthus (snowdrops) in many cultivars, Cyclamen, Trillium (local and out-of-state forms), Helleborus hybrids, uncommon Colchicum and Eranthis, plus regional novelties such as Adonis, Spigelia marilandica, and Iris dabashanensis. Collections are grouped across five principal microhabitats: raised beds, xeric beds, bog gardens, woodlands, and cold greenhouses.

Photography & Public Activities

Over more than twenty years, the gardener has assembled a photographic archive exceeding 20,000 images documenting the garden and its plants. The archive is published online on the Edgewood main site under Image Galleries, organized by genus and season, serving both as a visual record and an educational resource. The garden is not open for visits, but plants can be ordered online or purchased at seasonal plant sales and lecture events, with appearances scheduled in Pennsylvania, North Carolina, Delaware, Rhode Island and beyond.

Contact & Visiting Policy

Edgewood is not currently open to the public. Inquiries about plant availability, existing orders, upcoming sales, or speaking invitations can be sent via the Contact Us form on the main site. Because the garden is maintained by one person, most visitation requests cannot be accommodated; plant-related correspondence is answered first.
