美国旱地温室苗圃 Arid Lands Greenhouses – 长期保持三千余种多肉与仙人掌活体收藏

苗圃沿革与亚利桑那州沙漠温室

美国旱地温室苗圃 Arid Lands Greenhouses 位于亚利桑那州图森市西南郊的索诺兰沙漠边缘，是当地少数同时面向零售商与终端收藏爱好者、经营多肉与仙人掌批发兼零售业务的家族苗圃。苗圃现任主理人 Bob Webb 与 Toni Yocum 从事多肉与仙人掌栽培超过三十五年，其中 Toni 是土生土长的图森本地人；两人在多次前往非洲与阿拉伯半岛进行田野考察之后，于二十一世纪初接手经营这家温室苗圃。温室群常年保持冬季不低于华氏 42 度的最低温度，地址位于亚利桑那州图森市比尔比路西段，是亚利桑那州索诺兰沙漠中规模最大的多肉与仙人掌生产温室之一。

主营品类与批发零售双轨运营

苗圃长期保持三千余种多肉与仙人掌活体收藏，主要品类涵盖龙舌兰、芦荟、瓦苇、鲨鱼掌、回欢草、银蚕、裂榄、没药、福桂花科、大戟、棒锤树、天竺葵、虎尾兰与 Uncarina 等属，以及地下芽植物、瓜类蔬菜、萝藦科、粗壮木本植物、球兰、pachyforms、陆生凤梨与兰花、mesembs 番杏科以及各类球茎植物。除常规品种外，苗圃还经营大量通过野外考察收集的稀有与新近发表的物种，例如原产阿曼、也门、索科特拉、肯尼亚、坦桑尼亚、乌干达、马拉维、纳米比亚、博茨瓦纳与南非的狭域分布物种。

植物来源、田野考察与稀有品种引进

在经营层面，苗圃采取批发与零售并行的双轨模式。批发客户须提交亚利桑那州 5000 税表，最低起订量为批发清单中六株以上的两百美元植物，达到起订量后其余品种按七折供货，发往外地订单按实际运费结算并加收百分之十的装卸费。零售客户则可通过在线目录直接下单，苗圃全年发货并提供华氏 42 度以下的保温包选配，植物以裸根方式出货以确保根系健康并节省运费。营业时间为夏秋两季早七点至下午三点、冬春两季早八点至下午四点，周日至周一闭店。

出版物、教育资源与种植指南

苗圃不仅是商业机构，也是多肉与仙人掌学术交流的重要平台。主理人 Bob Webb 长期为多家学会与俱乐部做专题演讲，并与分类学家合作发表了多个龙舌兰属与虎尾兰属新种；苗圃还设立了自有出版品牌 Arid Lands Press，出版涵盖虎尾兰属物种图鉴以及未来计划中的大戟属、纳米比沙漠植物志等专著。网站另设分类学变更页面、资源推荐页面与初学者入门页面，介绍拉丁学名体系、土壤配比（浮石与有机质加粗砂各约一半）、盆栽选择、光照与通风、水肥管理以及冬季保温等栽培要点，为初学者与进阶收藏者提供系统的种植知识。

Nursery History and Arizona Desert Greenhouses

Arid Lands Greenhouses is a family-run succulent and cactus nursery located on the southwestern edge of Tucson, Arizona, in the Sonoran Desert, serving both wholesale buyers and retail collectors. The nursery is operated by Bob Webb and Toni Yocum, who have cultivated succulent plants for more than thirty-five years; Toni is a Tucson native, and the couple took over the greenhouse operation in the early 2000s after extensive botanical travels across Africa and the Arabian Peninsula. The greenhouse complex maintains winter minimum temperatures above 42 degrees Fahrenheit and houses one of the largest production collections of succulents and cacti in the Arizona Sonoran Desert.

Core Inventory and Wholesale-Retail Operations

The nursery maintains a living inventory of more than three thousand succulent and cactus species. Core genera include Agave, Aloe, Haworthia, Gasteria, Anacampseros, Avonia, Bursera, Commiphora, Fouquieria, Euphorbia, Pachypodium, Pelargonium, Sansevieria and Uncarina, together with geophytes, cucurbits, asclepiads, pachycaul trees, hoyas, pachyforms, terrestrial bromeliads and orchids, mesembs and bulbs. In addition to widely cultivated taxa, the nursery offers many rare and recently described species collected during field expeditions to Oman, Yemen, Socotra, Kenya, Tanzania, Uganda, Malawi, Namibia, Botswana and South Africa.

Plant Sourcing, Field Expeditions and Rare Taxa

The business operates a dual wholesale and retail model. Wholesale customers must supply an Arizona Form 5000 resale license; the minimum order is two hundred dollars of plants on the wholesale list with at least six individuals per species, and additional species are then priced at thirty percent off. Out-of-state wholesale shipments are billed exact shipping plus a ten percent handling fee. Retail customers order through the online catalog year-round, with plants shipped bare-root for plant health and reduced freight, and optional forty-two-degree heat packs offered in cold weather. Summer hours run from seven AM to three PM, fall-winter-spring hours from eight AM to four PM, with the nursery closed on Sundays and Mondays.

Publications, Educational Resources and Cultivation Guides

Beyond commerce, the nursery functions as a hub for succulent and cactus scholarship. Bob Webb frequently presents to cactus and succulent societies and has co-described new species in Agave and Sansevieria. The nursery runs its own publishing imprint, Arid Lands Press, whose first title is a pictorial guide to the genus Sansevieria, with future volumes planned on Euphorbia and the succulent flora of Namaqualand. The website maintains a taxonomic changes page, a beginner’s guide and a resources page covering Latin naming conventions, soil mixes of approximately fifty percent pumice, twenty-five percent organic matter and twenty-five percent coarse sand, container selection, light, airflow, watering, fertilization and winter protection, providing systematic cultivation knowledge for both newcomers and advanced collectors.
