It is wonderful to see how Treborth has inspired these talented writers. Dan Brown, Nigel’s son, was also inspired by Treborth as a young boy, and was taken out by his father on local botanising trips. Here he learnt about moonwort and he writes about this little treasure. Nigel also has written for us - his observations of wildlife in his garden on Anglesey. An unwelcome plant in the countryside is Himalayan balsam, which can carpet damp areas in the late summer, as Julian Brandram reports. We have several articles about developments at Treborth. Natalie Chivers reports on several of these and she includes some photographs of the many pots of bulbs there were planted up last year and are now providing a superb show. Pat Denne writes about the 30 years of moth and weather records that she has painstakingly entered on to a database – and appeals for someone to come forward to analyse them. Erle Randall tells you about an important but less public area of the Garden – the bonfire and compost site; this has been landscaped and now provides an essential service in dealing with the bulk of the waste vegetation we produce. There is also a report by Ann Illsley on a donation of books by Edyth Harrison, and an article by John Gorham on an intriguing little plant in the Tropical House. A new species was found in our wildlife pond, a saucer bug, and Matthew Hamer writes about this discovery. Treborth depends on the contribution of volunteers, and we like our readers to meet them through these pages: Marion Gash is profiled in this newsletter. Tomos Jones came up with an interesting idea at the Committee last year. We have a wealth of academic expertise among our contacts, so why don’t we call on these experts to give a series of botanical seminars for students and members? Good idea we said, and Tomos volunteered to organise it – and he writes about the very successful start of this new venture. And finally we have several articles about far flung places: Shaun Russell writes about plants in Chile and Richard Birch has been botanising in Crete, and I report on my recent trip to Central America. I hope you agree that yet again Angela has put together a fascinating collection of varied and interesting articles for this newsletter. From the responses we get after each newsletter is published, we know there is an appetite for thoughtful, knowledgeable and amusing writing about Treborth and the wider natural world. It was therefore with some sadness that I attended an event in March to mark the closure of another magazine, Natur Cymru – Nature in Wales. I know many of you were subscribers. This excellent magazine has been published four times a year since 2001, but could not continue after external funding sources 3 were withdrawn. While I acknowledge that public bodies are facing financial constraints, it is a great pity that a relatively small amount of money could not be found to keep Natur Cymru in publication. Sarah Edgar News in Brief · Erratum In the recent Newsletter No.58 Jan 2017, Fig 9 on page 25 was unfortunately incorrectly captioned: ‘Cattleya lodigesii’ should be 'Cattleya (Guarianthe) bowringiana'. Thanks go to Simon Retallick for pointing out the mistake. · Donations We should like to thank the following people who have kindly donated funds to the Friends: Joy Scott, Raj Jones, Greenwood Forest Park, Elizabeth McLelland, and Jane Smith and Brenda Haselgrove. Angela Thompson Curator’s Report, January – April 2017 As I sit writing my report, my peripheral vision is filled with the butter-yellow heads of the Narcissus flowering in the Welsh Fruit Orchard outside my office window. Spring has finally sprung and it is welcomed by the beautiful variety of spring flowering bulbs here at Treborth. All the hard work of the Friends over the winter months has paid off, and we have been treated to an explosion of flowers around the main buildings and across the lawns. I don’t think I can decide my favourite, although I am particularly drawn to the Eremurus × isabellinus 'Cleopatra' (foxtail lily). If you have these too then like ours the foliage is likely to just start peeping through the surface of the pot now, and soon they will produce tall spikes of burnt- orange flowers towards the end of May through June and July if the pot is placed in full sun. 4 So far this year we have been busy planning another spectacular herbaceous display - including sowing seeds and repotting for plant sales, courtyard pot preparations and tending to the Butterfly Border. We are continuing to develop the Chinese Garden, focussing on hardy medicinal ferns, peonies, and dwarf Rhododendrons as well as grasses and ground cover. The Friends and STAG have been hard at work clearing some of the rogue bamboo clumps from the woodland edge and meadow plots, and we plan to dig trenches around several of the clumps to restrict rhizomatous growth. The Long Borders have had a thorough prune and are now being colonised with some attractive ground cover as we develop a planting plan for the new open spaces. Our endemic Island flora bed shelter is now finished and Rosie is working with the Friends to establish a plant list encompassing the Canary Islands, Madagascar, St Helena and the Japanese Islands. We are also working closely with other botanic gardens, as plant material is not usually commercially accessible. Our efforts continue with the GLASTIR work schedule, including widening the path down past the Bog Garden onto the Welsh Coast Path. This will allow us to drive our all-terrain vehicle in a loop around the site, making surveying and maintenance more efficient. Strimming and clearing invasives has been on the agenda for the Arboretum, in preparation for new planting and to display engraved labels that not only identify each specimen tree, but introduce visitors through a ‘time-line’ to show the changing tree-scape of Wales. We are very fortunate to have been awarded three more internship opportunities in collaboration with the Bangor Employability Award. Sarah-Louise Ellis, Jemima Letts and Tom Morrissey who are Bangor University students, join the garden team to assist with the day-to-day gardening, as well as woodland management and working with GIS to create garden management maps. This is an excellent achievement of all who have been involved and I hope our students enjoy their time at the garden. STAG continue their commitment and endurance here at the garden, with two brilliant work parties achieving seed sowing, tree planting, bamboo clearing, and giving the Grevillea juniperina x rosmarinifolia 'Canberra Gem' a good prune on the Rock Garden. Cuttings have been taken and we hope to plant the boundary of the Rhizotron with seedlings to establish an attractive hedge. STAG finished for their Easter break with a brilliant botanising trip to Aberffraw led by Nigel Brown. Among many, the highlights of the trip were viewing Mibora minima (Early Sand- grass - the world’s smallest grass, confined, as a native, to coastal dune systems in Wales) and Tulostoma brumale (Winter Stalkball - a rare stalked puffball found in autumn and winter among moss or short grass mainly on sandy, alkaline soil).
