Friday 8th
Afternoon Tour/Garden visit to Dalemain mansion (Penrith)
This is a plantsman’s garden with an extraordinary breadth and depth of plant varieties. There are over 200 old-fashioned roses (June to July), a timeline of apple trees, nooks and crannies galore. The magnificent Silver Fir (Abies Cephalonica) which has the largest girth in the UK was a gift from Joseph Banks , the botanist, in the 1840s; and the Hymalayan blue poppies Mecanopsis grandis Dalemain were propagated by Sylvia Hasell. In the Spring carpets of snow drops, aconites and later daffodils splash colour over the still sleepy earth. Different fashions in horticulture echo around the space from the formality of the Elizabethan Knot Garden; the surrounding Romantic, landscaped parkland with glorious views out to the High Fells; the herbaceous terrace; and the wild garden drawing from the work of William Robinson. The garden is well known having won the Historic Houses Garden of the Year Award, sponsored by Christies in 2013 and is a Royal Horticultural Society Partner Garden

Past Events
January Online Talks




This event was organised by Tim Keyworth, SRS Tours & Events Manager.
SRS/RSCG Joint Autumn Conference
Benmore 11th Oct 2025 – Glenbranter 12th Oct
The conference began with a focus on rhododendron identification. The first two speakers gave an introduction to classification and also shared their knowledge on how to find the subsection, or even better, the name of a rhododendron species.

John Roy shows the distribution of species in the wild. R. barbatum, R. argipeplum and R. erosum spread from west to east. Matt Heasman explains the differences in flowers, leaves and other key markers.

Tim Keyworth then gave a talk updating us on the special rhododendron collections at some of the NTS gardens. Brodick has a very special R. magnificum originally collected by Frank Kingdon Ward. We were then told about the problems faced with maintaining the collections such as invasive species, plant diseases and erosion. Pathways at Crarae have been lost due to heavy erosion.

Before heading out for a guide tour round Benmore gardens, we were given demonstrations on how to propagate rhododendrons. Katrina Clow showed us how anyone can grow rhododendron from seed using a simple punnet on a windowsill and seed from the SRS seed exchange. John Nichols from Brodick showed us how they are preserving rhododendron species using an air-layering technique. Air-layering can have a very high success rate but does require a lot of patience.



Glenbranter
On Sunday we met up for a visit to the managed landscape of Glenbranter. With a mix of original plantings and more recent introductions, Glenbranter offers as naturalistic a setting as one can expect to find anywhere. The sheltered gully and high rainfall is the perfect environment for a collection of large leafed rhododendron species.



SRS members will be able to read more details of this event in ‘The World of the Rhododendron’.

Tayside Gardens Tour summery
2nd-4th May 2025
Day 1
The weekend tour starts off with a Friday afternoon tour round Braco Castle Gardens. Jodi Simpson was kind enough to share his knowledge while guiding us round the gardens. The woodlands, terraces, pond area and house surrounds hold an extensive range of rhododendrons and other hardy plants. The sunny weather enticed many of us to stay behind after the tour to soak in the atmosphere.

Day 2
The second day begins with a visit to the treasure trove that is Branklyn Gardens NTS. This compact garden is an outstanding setting which is an absolute must for any plant enthusiast. The famous rock garden is packed full of gems and the woodland area has many Rhododendrons in full flower. Plants are all well labelled and the grounds very well maintained by a dedicated team.




After mid-day refreshments, we then met up for a look round Dundee Botanic Gardens. A large arboretum provides a sanctuary to a wide range of trees and shrubs from around the world. The collection includes a well labelled rhododendron area. The well tended greenhouses with two different climatic zones are also a great asset to the gardens.
