加拿大 Chapman 鸢尾苗圃 – 加拿大历史最悠久、规模最大的有髯鸢尾专业苗圃之一

加拿大 Chapman 鸢尾苗圃 (Chapman Iris) 由 Chuck Chapman 于 1991 年在安大略省 Guelph 东北郊创立，是加拿大历史最悠久、规模最大的有髯鸢尾专业苗圃之一。苗圃以有髯鸢尾的育种、栽培与销售为主业，兼营西伯利亚鸢尾与 Spur 鸢尾等无髯品种，凭借三十余年的杂交选育经验，在北美寒地园艺圈享有盛誉。

苗圃概况

苗圃占地约 11 英亩，其中约 4 英亩用于成株与苗圃栽培，约半数面积留作实生苗选育圃，地处加拿大农业带 5b 区（对应美国农业部约 4b 区），土壤为沙壤土并富含石灰岩，自然缓冲至 pH 7.0。这一碱性土条件使 Chapman 难以兼顾路易斯安那鸢尾与日本鸢尾等酸性土偏好种，因此专注有髯鸢尾及其近缘类群。冬季最低温常低于 -36 °C，偶有 -40 °C 极寒且无稳定雪盖，苗圃通过栽植深度增加半英寸至一英寸、春季补植冻拔苗与灼烧老叶防蛀等方式应对寒害。

鸢尾品类与花期

苗圃主营有髯鸢尾全谱系七个类群：微型矮生有髯鸢尾 (MDB)、标准矮生有髯鸢尾 (SDB)、中间型有髯鸢尾 (IB)、微型高生有髯鸢尾 (MTB)、边缘有髯鸢尾 (BB)、高生有髯鸢尾 (TB) 以及有髯鸢尾原种 (Bearded Species)，并兼种西伯利亚鸢尾与 Spur 鸢尾。花期由五月中旬起、延续至七月中旬，依序为 MDB 约 5 月 15–19 日、SDB 约 5 月 22–29 日、IB 约 5 月 25–30 日、TB 约 6 月 9–19 日、西伯利亚鸢尾 6 月 12–20 日、Spur 鸢尾 7 月 1–15 日，构成完整的春末至盛夏观赏序列。

育种与新品种

Chuck Chapman 长期致力于抗寒有髯鸢尾杂交选育，2025 年正式推出塔利拜尔德 (TB) 新品种 ROSEMARY’S CENTURY（以 103 岁仍坚持园艺的岳母 Rosemary Brown 命名），并发布 7 个待命名实生苗，承诺采纳命名建议者将获赠该苗分株。历年来代表性品种包括 1999 年育成的 MDB BANTAM PRINCE、2009 年育成的 SDB BLACK LIGHTNING（耐寒黑花系列）、2021 年育成的 SDB BASS NOTE（luminata-plicata 复合斑纹），展现出从微型到高生的完整育种线。苗圃遵循美国鸢尾学会 (AIS) 评价体系，参照荣誉奖 (HM)、优异奖 (AM) 及 Dykes Medal 等奖项评定品种表现，Chapman 本人长期参与 AIS 认证展会与种子苗评估，其选育的品种多次获 EC（展示证书）与 HC（高度认可）等级评定。

订购与开放参观

苗圃采用纯网络订购方式，无印刷目录。最小起订金额 30 加元（不含包装运费），截单日为 7 月 24 日，订单自 7 月下旬起至 8 月底分批发货；3 区及更寒冷地区客户须提前至 7 月 16 日下单以获得越冬成活保证，美国客户以美元结算并从纽约州 Lewiston 中转发货。开放参观采取预约制，参观者可通过电邮联系 Chuck 安排到访时段，园区工作日 8 时至 20 时开放，建议访客准备合适户外鞋具，雨季泥泞尤需注意。

Overview

Chapman Iris is a Canadian bearded iris specialty nursery founded in 1991 by hybridizer Chuck Chapman on roughly 11 acres of sandy-loam farmland northeast of Guelph, Ontario. It is among the oldest and largest bearded iris growers in Canada, breeding and selling tall, standard dwarf, intermediate, miniature tall, border, miniature dwarf and species bearded iris adapted to cold-climate Canadian gardens, with supplementary collections of Siberian and Spuria iris.

The Nursery

The property lies in Canadian plant hardiness zone 5b (approximately USDA zone 4b) on naturally buffered limestone soil at pH 7.0, which has shaped the collection’s focus on bearded iris over acid-loving Louisiana and Japanese iris. About 4 of the 11 acres are planted to bearded iris and seedling beds, with winter temperatures regularly falling below -36 °C and occasionally to -40 °C under inconsistent snow cover; the nursery responds with deeper planting, spring replacement of frost-heaved plants, controlled spring rot treatment and a burn-and-spray regime against iris borer.

Iris Classes and Bloom Season

Chapman Iris maintains the full bearded iris spectrum — Miniature Dwarf (MDB), Standard Dwarf (SDB), Intermediate (IB), Miniature Tall (MTB), Border (BB), Tall Bearded (TB) and Bearded Species — alongside Siberian and Spuria iris. Peak bloom moves through the garden from mid-May into mid-July: MDB around May 15–19, SDB around May 22–29, IB around May 25–30, TB around June 9–19, Siberian iris June 12–20 and Spuria iris July 1–15, giving visitors a sequential six-week display.

Hybridizing and New Introductions

Chuck Chapman focuses on cold-hardy bearded iris lines, releasing the 2025 Tall Bearded introduction ROSEMARY’S CENTURY — a hardy garden performer named for his 103-year-old mother-in-law Rosemary Brown — together with seven unnamed seedling selections whose adopters may suggest cultivar names. Earlier releases include the 1999 MDB BANTAM PRINCE, the 2009 SDB BLACK LIGHTNING (a ruffled near-black with violet beard) and the 2021 luminata-plicata SDB BASS NOTE, documenting a continuous hybridizing program from miniature dwarfs through tall beardeds. Cultivars are evaluated against the American Iris Society (AIS) framework — Honourable Mention (HM), Award of Merit (AM) and the annual Dykes Medal — and Chapman seedlings have received Exhibition Certificate (EC) and High Commendation (HC) recognition in AIS-accredited shows.

Ordering and Visits

The nursery sells exclusively through its website, with no printed catalogue. Minimum order is 30 dollars before packing and shipping, the order cutoff is July 24 and bearded iris ship from late July through the end of August; customers in zone 3 and colder must order by July 16 for an over-winter survival guarantee, and USA orders are paid in US dollars and consolidated through Lewiston, New York. Garden visits are by appointment; the property is generally open daily 8 a.m. to 8 p.m. during the growing season, and visitors should bring suitable footwear for muddy rows after rain.
