The Development of the Royal Botanic Garden Edinburgh ‘Certificate in Practical Horticulture’
The Royal Botanic Garden Edinburgh (RBGE) has a long history of delivering high-quality practical horticultural training within the UK and abroad. In 2007 this training was formalised by the RBGE Education Department into the ‘RBGE Certificate in Practical Horticulture’ (CPH) programme. The vision for the CPH was to create an internationally recognised and standardised, yet flexible and practical horticultural qualification, predominantly, but not exclusively, for the botanic gardens sector. Providing a measurable educational outcome for international development projects is increasing the contribution that RBGE makes to target 15 of the Global Strategy for Plant Conservation. This paper reviews the development of the CPH programme, through its initial conception, the writing of the first course syllabus, the evolution of the course structure and content, up to the course now being offered today. The initial success of the CPH is discussed, detailing the different locations in which the course has been delivered to date and the other gardens that are now offering the CPH themselves. Recent developments are discussed, including the endorsement of the course by Botanic Gardens Conservation International (BGCI) and the funding awarded by the Stanley Smith (UK) Horticultural Trust in 2010 for course development. The paper ends by highlighting the future objectives for the CPH, including the development of new and improved tutor and learner support materials, the offering of ‘train the trainer’ programmes that will facilitate the wider uptake of these courses and the vision for the programme to become a benchmark for practical horticultural training worldwide
Diplycosia Blume: A Little-Known Genus of the Ericaceae from South-east Asia Cultivated Under Glass at the Royal Botanic Garden Edinburgh
The Royal Botanic Garden Edinburgh holds a number of small and understudied collections in the glasshouses at Edinburgh about which relatively little is known. This paper introduces one of these genera. A brief introduction and history is given of the genus Diplycosia Blume. An outline of the literature and a summary of their distribution, along with an overview and history of the collections held at Edinburgh, are also presented, as are cultivation notes. All plant names in this paper have been cross-referenced using the International Plant Names Index website (International Plant Names Index, 2010)
Data Capture and Taxonomic Determination of Cycadales at the Royal Botanic Garden Edinburgh
This paper discusses a curatorial review of the Cycadales in the Living Collection at the Royal Botanic Garden Edinburgh (RBGE) following the methodology described by Frachon et al. (2009). It provides an understanding of the cycads in the Living Collection and the diversity of the group represented at RBGE. The paper also describes the determination process and any changes in identification during the course of the project. This project was carried out as part of the second year project of the HND in Horticulture with Plantsmanship at RBGE
Meconopsis grandis: The True Himalayan Blue Poppy and the Cultivation of Meconopsis grandis
The history of Meconopsis grandis is described and the species analysed in the light of collections made since George Taylor’s monograph of the genus in 1934. Two new subspecies, subsp. orientalis Grey-Wilson and subsp. jumlaensis Grey-Wilson, are described based on both morphological and geographical separation. Hybrids between M. grandis and the allied M. baileyi are assessed. Techniques for the cultivation of M. grandis are also given
Prioritisation for the Conservation of Cultivated Plants: A new approach
In this paper, the case for the conservation of plants that have arisen in cultivation is provided and the mechanisms for extinction discussed, with examples. The approach to cultivated plant conservation over the past 30 years is reviewed and a basis for revising that approach explained. A new, far more comprehensive and rigorous method for prioritisation is proposed. This has been developed for the Plant Heritage Threatened Plants Project
Field Collecting Living Material in Papua, Indonesia
This paper sets out ‘best practice’ methods for field collecting wild material, based on experience gained during a two-month expedition to the Indonesian province of Papua. The horticultural team involved in the trip sought to keep cuttings, rhizomes, seedlings, whole plants, seeds and spores intact and healthy while in the field. With several obstacles including climate and lengthy delays in transportation to deal with, the high success rate of collected material is testament to the careful techniques employed in the processing of living plant material in the field
Raising the living dead: Ramosmania rodriguesii
‘Living dead’ is a term biologists have begun to use to describe those species that are not expected to escape extinction without significant human intervention (Janzen, 2001), such as captive breeding or cultivation. While the number of taxa that fall into this category continues to increase, this paper reports on a species that may beat the odds and escape its fate, after decades of cultivation at the Royal Botanic Gardens, Kew. An account of the historical facts that led to the recovery of the species in question, Ramosmania rodriguesii, and the latest update regarding its current situation are provided along with cultivation notes
