网站与两家合作苗圃
repo-pflanzen.de 是两家德国宿根植物苗圃合办的供货网站，站内自报的身份是复垦植物供应方。一家是哈默尔恩的 Stauden Junge，由 Matthias Großmann 经营，1896 年起做宿根苗圃，1970 年迁到城郊；另一家是 Petrowsky 苗圃，Jörg Petrowsky 于 1985 年建场，场址在吕讷堡石楠草原的南边，专做沼泽植物、水生植物和睡莲。供货量大小都做：住宅用的澄清池只收小批量，市政项目则供大批量，例如污水厂末级的那一段澄清池。两家苗圃都做湿地生境的复垦与再自然化，这是它们和普通观赏苗圃的区别所在。同一站点也以 schilfpflanzen.de 对外开放，内容完全一致。
复垦植物是什么
德语里的 Repositionspflanzen 指的是用于复垦和再自然化的宿根植物与木本植物，词源是拉丁语 reponere，意思是重新安放、恢复。这批植物是原产中欧、在野外自然状态下生长的野生宿根，没有经过杂交或选育来改变性状。网站把苗木品质当成成败的关键：露天栽植面对的是土壤状况、水位高低、栽植时间和日后能不能养护这些条件，货不对板会直接反映在成活率上，所以品质是否稳定是这类供货里最难的一环。
芦苇与净化用途
芦苇 Phragmites australis 是这个网站的主角，站内专门为它做了一页。它从周期性干涸的岸边一直到 1 米水深都能扎根，耐得住养分、pH 值和盐分的起伏，适合湿生裸地的先锋定居，株高可达 3 米，靠根茎和种子扩散；同属的 subsp. pseudodonax 更壮，能长到 7 到 10 米。芦苇秆自古就是建筑材料，可做保温层和遮挡墙，作燃料时每公斤 6000 千卡，是褐煤的两倍；波罗的海沿岸、匈牙利、波兰、奥地利和乌克兰都有采收传统，一公顷年产可达 17 吨，刈割还能抑制底泥堆积。在植物净化厂里，芦苇占种植量的八到九成，余下份额由香蒲、黄菖蒲、灯心草和薹草分担。
品种表与供货方式
网站的品种表列出 57 种植物，逐条标注主导植物、供氧、净化作用、物种保护、固岸功能、适宜水位和株高等项目，涵盖菖蒲、水薄荷、黄菖蒲、薹草、睡莲、荸荠、香蒲这一类沼泽与水生植物。供货上有两点值得留意：常年备有 8 厘米和 9 厘米两种盆径的复垦植物苗，随时可发；也可以按项目签订合同种植，绕开库存按栽植时间安排生产，球根体积和栽培基质都能另行商定。
质量标准与应用清单
质量方面，两家园艺场按德国 DIN 的宿根植物质量规范作自愿检查，并把这一条写进各自的介绍；两家也都是 ZVG 园艺业联合会、德国宿根园艺师协会 BdS 和国际宿根植物联盟 ISU 的成员。应用清单同样具体：复垦植物可用于植物净化厂、传统污水厂的深度净化、污泥堆肥、雨水与地表水的下渗、封闭系统的植物过滤回用、生态泳池、渗水沟和护岸，也能让砾石坑、河道、静水、露天矿坑和废石堆重新长出自然植被。网站另备有 5 厘米和 8/9 厘米规格芦苇草束的产品说明与招标用清单文本，可直接取用。
The Site and Its Two Partner Nurseries
repo-pflanzen.de is a supply site run jointly by two German perennial nurseries, and the site names its own role plainly: it supplies reposition plants. One is Stauden Junge in Hameln, run by Matthias Großmann, a perennial nursery since 1896 that moved out to the edge of town in 1970. The other is the Petrowsky nursery, founded by Jörg Petrowsky in 1985 and set in the southern Lüneburg Heath, where it specialises in marsh plants, water plants and water lilies. Both quantities are handled: settling tanks at private houses need only small amounts, while municipal works such as the final clarification stage of a sewage treatment plant take large deliveries. Re-cultivating and renaturing wet habitats is the work that sets the two nurseries apart from ordinary ornamental nurseries. The same site is also served at schilfpflanzen.de, with identical content.
What Reposition Plants Are
In German, Repositionspflanzen are the perennials and woody plants used for recultivation and renaturation, and the word comes from the Latin reponere, to put in place again, to restore. These are wild perennials native to Central Europe that grow in open country under natural conditions, and they have not been altered by crossing or by selection. The site treats plant quality as the decisive factor: open planting has to cope with soil, water level, planting date and how much care is possible afterwards, so a delivery that does not match the site shows up directly in the survival rate. Keeping quality steady from one batch to the next is the hardest part of this kind of supply.
Reed and Its Use in Water Treatment
Phragmites australis, the common reed, is the plant this site is built around, and it has a page of its own. It takes hold anywhere from a bank that dries out periodically down to a metre of water depth, tolerates swings in nutrients, pH and salt, and suits the first colonisation of wet raw soils. It grows to three metres and spreads by rhizome and by seed, while the subspecies pseudodonax is more vigorous still and reaches seven to ten metres. Reed stems have long been a building material, used for insulation and as screening, and as fuel they carry 6000 kilocalories per kilogram, twice the figure for lignite. The Baltic coast, Hungary, Poland, Austria and Ukraine all have a tradition of harvesting it, a hectare can yield seventeen tonnes, and mowing holds back the sludge that builds up. In a planted treatment plant reed takes up eighty to ninety per cent of the planting, the balance being made up of bulrush, yellow iris, rush and sedge.
The Plant List and How Supply Works
The plant table lists 57 species, each marked for its leading role, oxygen contribution, cleansing effect, nature conservation value, securing function, suitable water depth and height, covering plants such as sweet flag, water mint, yellow iris, sedge, water lily, spike rush and bulrush. Two aspects of supply are worth noting. There is always stock of reposition plants in 8 and 9 cm pots, ready to go out at short notice. And for larger projects the nurseries work to contract, growing to order around the planting date rather than from stock, with the volume of the root balls and the growing substrate settled separately in advance.
Quality Standards and the List of Uses
On quality, both nurseries carry out voluntary checks against the German DIN standard for perennial quality, and both say so in their own introductions. Both are also members of the ZVG gardening federation, the BdS association of German perennial growers and the ISU international perennial union. The list of uses is equally concrete: reposition plants for planted sewage treatment plants, for final clarification after conventional treatment, for sewage sludge composting, for the infiltration of rain and surface water, for water recycling through plant filters in closed systems, for natural swimming ponds, for infiltration basins and for bank protection, and for bringing plant cover back to gravel pits, streams, still waters, open-cast mines and spoil heaps. The site also offers product descriptions and specification texts for tender documents, in reed bundles of 5 cm and of 8/9 cm, ready for use.

The two nurseries behind the site are Stauden Junge, a perennial nursery in Hameln, and the Petrowsky nursery for marsh and water plants in Eschede, whose own site is seerosensorten.de.
