美国鸢尾城市花园 Iris City Gardens – 田纳西州 32 年家族经营的鸢尾专业苗圃

Iris City Gardens（鸢尾城市花园）是一家位于美国田纳西州的家族式鸢尾专业苗圃，由 Macey 与 Greg McCullough 夫妇共同经营，自 1994 年起持续运营至今，2026 年迎来第 32 个栽培年度。

苗圃历史与所在地区

苗圃位于田纳西州 Primm Springs 小镇，毗邻纳什维尔（Nashville）西南约 40 英里处的乡间，靠近 840 号州际公路 7 号出口，海拔约 200 米，处于 USDA 6b-7a 园艺带，夏季湿热、冬季温和，恰好适合路易斯安那鸢尾喜湿热土壤的习性，也是中南部有髯鸢尾传统种植带之一。Macey McCullough 长期负责栽培与杂交育种，Greg McCullough 负责园务与访客接待，夫妇两人把一片乡间田地建设成兼具苗圃、展示园与家庭工作室功能的复合型花园。32 年的连续运营使苗圃积累了稳定的有髯鸢尾、路易斯安那鸢尾、芍药与萱草品系，并多次入选美国鸢尾协会（American Iris Society）地区展示名单。

主营品种与花期节奏

苗圃主营四大类多年生草本：路易斯安那鸢尾、有髯鸢尾、芍药与萱草，并辅以其他多年生盆栽植物。路易斯安那鸢尾是核心品类之一，包含 ‘Rings of Romeo’、’Reverchon Snowfall’、’Eyes Wide Open’、’Oriental Parasol’ 等已注册品种，强调湿地适应性与六月初的晚花期。有髯鸢尾分为高大型（TB）与多次开花（rebloomer）两类，rebloomer 自春季首花后可在 6 月至 11 月持续开放，依天气条件再开 2 至 3 次。苗圃年度花期节奏为：有髯鸢尾 4 月底至 5 月中、路易斯安那鸢尾 5 月中至 6 月初、芍药 5 月中前后、萱草 6 月中，是中南部少有的把四大类多年生草本按时间序列串成完整花期带的私人苗圃。

Iris City Gardens is a family-owned iris nursery located in Primm Springs, Tennessee, USA, run by Macey and Greg McCullough. Founded in 1994, the garden is now in its 32nd growing year as of 2026. Set about 40 miles southwest of Nashville just off Interstate 840 Exit 7, the property combines a working iris nursery, display beds, and a visitor-friendly country garden where guests are invited to bring a picnic and stay for the day.

Nursery History and Location

Founded in 1994 on what began as a family garden, Iris City Gardens has grown over three decades into a small specialty nursery open to the public during bloom season. Macey McCullough oversees the iris beds and hybridizing work, while Greg McCullough manages grounds and visitor hospitality, and together they have turned a stretch of rural Tennessee farmland into a combined nursery, display garden, and family studio. Primm Springs sits at the border of Hickman and Williamson counties at roughly 200 m elevation, within USDA hardiness zones 6b to 7a, where hot humid summers and mild winters suit Louisiana iris perfectly while still supporting bearded iris, peonies, and daylilies. Thirty-two continuous years of operation have given the McCulloughs a stable breeding pool across bearded iris, Louisiana iris, peonies, and daylilies, and the garden has been listed in American Iris Society regional display schedules for many seasons.

Plant Collection and Bloom Calendar

The nursery carries four main perennial groups: Louisiana iris, bearded iris, peonies, and daylilies, plus a rotating selection of other potted perennials. Louisiana iris is the second pillar of the catalog alongside bearded iris and includes named cultivars such as ‘Rings of Romeo’, ‘Reverchon Snowfall’, ‘Eyes Wide Open’, and ‘Oriental Parasol’, all bred for wetland tolerance and early-June bloom. Bearded iris is divided into tall bearded (TB) and reblooming types; the rebloomers flower in spring and then again from June through November, producing two to three cycles depending on weather. The annual bloom sequence runs tall bearded from late April to mid-May, Louisiana iris from mid-May to early June, peonies peaking around mid-May, and daylilies in mid-June, making Iris City Gardens one of the few small private nurseries in the mid-South that strings these four perennial groups into a single continuous bloom season.

Visiting Hours and Pot-Only Sales

The nursery opens to the public from April 15 through June 28 each year, Wednesday through Sunday from 9 am to 4 pm Central time, and is closed Monday and Tuesday for grounds work; visits outside that window are by appointment. Picnic tables are provided on site, and visitors are encouraged to bring a lunch, family, and pets and spend the day, with the McCulloughs typically checking in to update guests on current bloom progress and recommending a phone call close to the planned visit date to confirm weather-driven schedule changes. Sales are strictly potted, on-site only: the nursery no longer takes mail orders, does not ship in spring, and does not export internationally. Louisiana iris orders are accepted only through September 1 and ship in September; there is no online ordering system, and customers place orders by downloading and printing the order form, then mailing, faxing, emailing, or phoning it in.

Website and Ordering

The official Iris City Gardens website hosts the current catalog in PDF form, printable order form, general cultural and shipping notes, and a visitor preview gallery titled At The Farm, plus driving directions from I-40/West Nashville, I-65/South Nashville/Franklin, Columbia, and Dickson. Customers who cannot visit during bloom season are advised to download the PDF catalog, print the order form, complete it at home, and mail or fax it back; credit card and check payments are both accepted. The McCulloughs encourage visitors to flag any broken links, misspelled words, or misidentified plants they encounter on the site.
