收藏者与站点
baumpfingstrosen.de 是德国北莱茵-威斯特法伦州杜塞尔多夫市(邮编 40468)Gerhard Kleinhans 私人维护的紫斑牡丹专题站点,Kleinhans 同时在该市 Ulanenstraße 17 留有通信地址,联系邮箱为 info@baumpfingstrosen.de。站点自述主页陈列了十余张 Rockii 牡丹花卉摄影照片,水印统一标注 baumpfingstrosen.de,首页顶部 Joomla! 版权信息亦指向 Kleinhans。该站非商业苗圃,而是个人长期收集、繁殖与品种交换记录。
收藏对象与品种范围
站点收藏对象为 Rockii 系牡丹(Paeonia rockii / Paeonia suffruticosa Rockii 亚组),也就是德国园艺界所称的 Strauch- 或 Baumpfingstrosen。这一类群以花瓣基部带深紫黑色斑块为主要识别特征,植株木质化、耐寒且少病害,在德国干旱夏季与零下冬季均能稳定生长。主页内容明确提到,因 Rockii 牡丹数量众多而场地有限,Kleinhans 同时也栽培 Lutea 牡丹与较新的 Itoh 杂交牡丹,以丰富其木本牡丹谱系。
繁殖与交换方式
主页信息显示,多余的 Rockii 牡丹以「嫁接苗加邮资」的低价出让,品种为重复或相近者。Kleinhans 同时欢迎与其他 Rockii、Lutea、Itoh 系列做植株交换,八月底起的嫁接窗口可用带芽枝条进行靠接,嫁接操作通常只在特殊情况下进行。此外若有空间充足的爱好者,Kleinhans 也愿意把收藏中部分植株整批出让,前提是对方能提供安置场地。
气候适应与日常管理
Rockii 牡丹在德国环境下表现稳定,与一般草本芍药相比,夏季耐旱、冬季耐寒,日常管理以低维护为主。站点表述指出这类植株比很多其他牡丹需要更少的照看,Kleinhans 也以此作为长期持有大型收藏的可行性基础。站点的图文记录显示 Rockii 牡丹从早春抽叶、暮春开花,到夏秋木质化枝条增粗,整个物候进程在德国西部温带海洋性气候下节奏平稳。
站点现状与联系方式
主页结尾声明,网站有相当部分内容因一次黑客攻击(Hackerangriff)暂时无法访问,Joomla! 框架恢复工作尚在进行中,只余下 Rockii 牡丹主题的核心页与花卉图集仍在公开可访问的状态。Kleinhans 留下 E-Mail 与邮政地址两条联系渠道,以便其他收藏者就品种交换、嫁接枝条或整株出让事宜直接取得联系,无需通过中间商。
Collector and Site
baumpfingstrosen.de is a personal Rockii tree-peony site maintained by Gerhard Kleinhans in Düsseldorf (postal code 40468), North Rhine-Westphalia, Germany. The postal contact is Ulanenstraße 17, with email at info@baumpfingstrosen.de. The site header carries Kleinhans’ name in the Joomla! metadata, and the homepage gallery watermarks every photograph with the baumpfingstrosen.de domain. It is not a commercial nursery but a private long-term collection, propagation and plant-exchange log.
Collection Scope
The focus is the Rockii group (Paeonia rockii / Paeonia suffruticosa Rockii subgroup), referred to in German horticultural usage as Strauch- or Baumpfingstrosen. Plants are identified by the dark purple-black blotch at the base of each petal. The shrubs are woody-stemmed, cold-hardy and largely disease-free, holding up through dry German summers and freezing winters alike. The homepage also notes that Kleinhans grows Lutea tree peonies and newer Itoh intersectional hybrids alongside the Rockii material to broaden the woody peony range.
Propagation and Exchange
Surplus Rockii plants are released at low prices (grafted plant plus postage), with duplicates and near-duplicates offered first. Kleinhans also accepts exchanges with other Rockii, Lutea and Itoh lines, and runs a budding window from late August when scion cuttings with buds are usable for grafting. Grafting itself is only done on request in exceptional cases. If a grower has the space, parts of the collection can be passed on in larger batches, provided the recipient can house the plants.
Climate Adaptation and Care
Rockii peonies are notably stable under German conditions. Compared with many herbaceous peonies they need little routine care, which is what allows a single grower to hold a large collection. The site records the full phenological cycle in the temperate-oceanic climate of western Germany: spring leaf-out, late-spring bloom, and summer-to-autumn woody-stem thickening on the same plant. Hardiness and drought tolerance are the practical reasons the collection has stayed in place for years.
Site Status and Contact
The homepage closes by noting that a large part of the website has been offline since a hacker attack, with the Joomla! framework still being restored. Only the core Rockii pages and the flower gallery are currently reachable. Kleinhans lists both email and postal address as direct contact channels for exchange partners, scion requests or whole-plant transfer, with no intermediary or sales platform involved.
