美国 Draycott 花园 – 获取西伯利亚鸢尾、日本鸢尾、拟鸢尾及稀有 Spec-X 鸢尾品种的主要来源之一

Draycott Gardens（Draycott 花园）是一家位于美国马里兰州巴尔的摩县北部 Upperco 镇的家庭式邮购苗圃，由 Carol Warner 单独经营，专精无髯鸢尾（beardless irises）多年，是北美爱好者和收藏家获取西伯利亚鸢尾、日本鸢尾、拟鸢尾及稀有 Spec-X 鸢尾品种的主要来源之一。

苗圃概况与所在地

Draycott Gardens 由 Carol Warner 在自家住宅经营，地址位于马里兰州 Upperco 的 Falls Road（MD 25 公路沿线），苗圃无店招、无固定营业时间，也不设现场零售，是纯粹的邮购型家庭苗圃。访客需提前电话预约方可参观苗圃内的展示花园与种苗区，参观季节依品种而异——西伯利亚鸢尾盛花期约在 5 月 18 日至 31 日，拟鸢尾与日本鸢尾则在 6 月 15 日至 7 月 1 日前后进入盛花期。苗圃同时承担鸢尾育种与新品种发布的功能，由 Carol Warner 本人及两位长期合作育种人共同推进。

主营鸢尾种类与目录规模

苗圃以无髯鸢尾为绝对核心，覆盖四大类群：西伯利亚鸢尾（Siberian irises）、日本鸢尾（Japanese irises）、拟鸢尾（Pseudatas，黄菖蒲与日本鸢尾的属间杂交）以及 Spec-X 系列（西伯利亚鸢尾血统的种间杂交）。此外目录还收录 Spuria 鸢尾、鸢尾（Iris tectorum，”日本屋顶鸢尾”）、Laevigata（喜湿水鸢尾）以及北美东部的 Versicolor/Virginica 系列。苗圃每年发布印刷版目录与可下载的 PDF 订货单，目录采用花园电子化形式运营，不接受网站在线下单或信用卡付款，是典型的”老派”专业鸢尾专类苗圃。

新品种与育种合作

Carol Warner 与两位外部育种人长期合作推出新品种。一是位于缅因州波特兰市的珠宝商 Dean Cole，他利用已故导师 Currier McEwen 培育的四倍体西伯利亚鸢尾亲本继续杂交，自 2021 年起陆续发布’Amethyst Frost’、’Ruby Peacock’、’Lemon Quartz’、’Topaz Ruffles’、’Beespeckled’ 及 2026 年的’Timeless Ruby’ 等四倍体西伯利亚鸢尾品种；二是日本育种家 Hiroshi Shimizu（清水），他专注于拟鸢尾与日本鸢尾的杂交，苗圃已陆续引进’Akimatsuri’、’Byakuya No Kuni’、’Benibutae’、’Chaki’、’Ause’、’Chastubo’ 及’Shimo Murasaki’（”紫里”，16 英寸矮生拟鸢尾）等多个特色品种。合作育种人均通过 Carol Warner 与北美爱好者建立联系。

栽培建议与订购政策

苗圃在网站专设 Culture 页面提供详尽的栽培指南：无髯鸢尾偏好富含有机质的微酸性土壤，喜湿但忌长期冰层覆盖；定植株距需保持”每 3–4 年分栽一次”的节奏；日本鸢尾尤其需要酸性土与额外水分；施肥推荐春秋两次平衡肥（如 10-10-10），不可在晚秋施肥以免刺激冬季徒长。订购政策方面，订单最低 15 美元，需以支票或汇票付款，9 月 10 日后停止接单；美国境内运费按密西西比河以东/以西分档收取，国际订单需另付 62 美元植物检疫证书费用；植株为裸根新鲜起苗，周一、周二通过美国邮政 Priority Mail 发货，并随单附栽培说明。

Draycott Gardens is a long-running home-based mail-order nursery in Upperco, Maryland, devoted exclusively to beardless irises. Run by Carol Warner from her residence, the nursery is one of North America’s principal sources for Siberian, Japanese, Pseudata, and Spec-X irises, and also publishes new cultivar introductions from external hybridizers Dean Cole and Hiroshi Shimizu.

Nursery Background and Location

Draycott Gardens is operated by Carol Warner as a one-person home-based nursery on Falls Road in Upperco, in northern Baltimore County, Maryland. The nursery operates strictly by mail order, with no on-site sales, no signs, and no regular business hours; visitors are welcomed to the display gardens and stock beds only by appointment. Peak bloom timing varies by iris type — Siberian irises peak around May 18–31, while Pseudatas and Japanese irises bloom roughly June 15 to July 1, with Pseudatas slightly earlier. The nursery combines retail mail-order with active hybridizing work, with Carol Warner handling day-to-day operations and customer orders personally.

Catalog Scope and Iris Groups

Beardless irises are the exclusive focus of the catalog. Four major groups anchor the listings: Siberian irises (Iris sibirica cultivars), Japanese irises (I. ensata), Pseudatas (intersectional hybrids of I. pseudacorus and I. ensata), and the Spec-X series of species-crosses involving Siberian parentage. Smaller sections cover Spuria irises, I. tectorum (the Japanese roof iris), moisture-loving Laevigata irises, and North American native Versicolor and Virginica irises and their hybrids. The nursery distributes its catalog electronically as a PDF order form and does not accept online ordering or credit card payments, in keeping with its traditional, mail-order-only character.

New Introductions and Hybridizers

Two external hybridizers supply most of Draycott’s recent introductions. Dean Cole, a jeweler based in Portland, Maine, continues the tetraploid Siberian line developed by his late mentor Currier McEwen and has released a steady stream of new cultivars through the nursery: ‘Amethyst Frost’, ‘Ruby Peacock’, ‘Beespeckled’ (2021), ‘Lemon Quartz’, ‘Topaz Ruffles’ (2022), and the 2026 release ‘Timeless Ruby’, a ruffled deep rose-red tetraploid Siberian with a gold edge and blue flash. Japanese breeder Hiroshi Shimizu contributes a parallel stream of Pseudata and Japanese iris introductions including ‘Akimatsuri’, ‘Byakuya No Kuni’ (the “land of the midnight sun”), ‘Benibutae’, ‘Chaki’, ‘Ause’, ‘Chastubo’, and the dwarf ‘Shimo Murasaki’ (16 inches). All new introductions are trialed and increased at Upperco before release.

Cultural Guidance and Ordering

The nursery publishes a thorough Culture page covering soil preparation, planting depth, watering, mulching, transplanting intervals, fertilizing, and pest control for beardless irises. Key recommendations include rich organic soils, acidic conditions for Japanese irises, regular division every three to four years, balanced spring and post-bloom feeding, and avoidance of late-fall fertilization that can force tender winter growth. Orders require a $15 minimum, payment by check or money order, and must be received by September 10; plants ship bare-root, freshly dug, via U.S. Priority Mail on Mondays and Tuesdays. Shipping is tiered east or west of the Mississippi; international orders pay a $62 phytosanitary certificate fee; a printed culture sheet accompanies every shipment.
