|2009||20 May: Centenary of the foundation of Hampstead Garden Suburb Horticultural Society by Dame Henrietta Barnett and early residents.
With no special anniversaries this year, the society enjoys its usual lectures, a Winter supper quiz evening, coach trips, the Plant Sale, Summer and Autumn Flower Shows, the Suburb in Bloom competition and the Scarecrow competition at the June show, judged as usual by Jonathan Ross and Jane Goldman.
In January, the Society hosts a lecture jointly with Hampstead Authors Society for a talk on the history of the rose by local author, Jennifer Potter. In February, a packed Fellowship House sees another innovation - the Society's first ever 'Seed Swap', backed up by a lecture and workshop on growing seeds. From now on a seed swap will be held every other year. A donation is made to Abbeyfield Residential Home in Erskine Hill and committee members' assistance is given to improve the main flowerbed there. Many members open their gardens on 19 June in aid of the North London Hospice and the Society. This event is combined with a small rose festival and teas in Fellowship House. There are several enjoyable outings and more lectures, as well as two successful flower shows, with Grimsdyke Brass paying a return visit to the September show.
Apart from all the usual annual activities, outings, etc., the Society organised its first-ever three-day excursion from 8-10 July - to six beautiful gardens in Norfolk and Suffolk. At the June Show, Hon President Jonathan Ross judged a highly suggesful children's fancy dress competition (with the children dressed as flowers, fruit or vegetables), and an adults' fancy hats competition on the same theme. At the September show, Grimsdyke Brass from Harrow paid a return visit to play in the garden of the Free Church Hall.
A year with both historical highs and lows. On 11 June, three members, Diane Berger, Marjorie Harris and Yvonne Oliver, were honoured by a highly-successful and enjoyable visit to their gardens by HRH Prince Edward, Earl of Wessex, in his capacity as Patron of the London Gardens Society. Due to the terrible winter and late spring, the Summer Show in June was lacking in many of its usual entries, ie, very unusually, there was no soft fruit at all on display. However, by contrast, the Autumn Show in September had one of the best and largest displays ever, due to the warm summer, including five trugs full of beautiful vegetables and salads, which is a higher number than anyone can remember. As usual, Jonathan Ross judged the fancy dress and fancy hats competitions in June and Grimsdyke Brass entertained the crowd at the September Show. At the AGM held in November, Yvonne Oliver was elected as the society's first Vice-Chairman, and was also very successful in the London Gardens Society small front and back gardens competitions.
The Society maintained its membership levels at approximately 400, and had a good year, with a varied programme of events and good weather for gardening and growing. This meant that more people were able to enter all the classes in the shows, which were both successful in terms of numbers of entries and visitors. Jonathan Ross opened the show and judged the children's fancy dress and adults' fancy hats in June and Grimsdyke Brass paid another return visit to the September show. During the summer, children created miniature gardens and planted flowers at an event held at the Garden Suburb Community Library for the first time. The Society also welcomed Jim Buttress and friends for a well-attended Gardeners' Question Time. This year, the majority of meetings were held in the small hall of the Free Church Hall in Northway during the period of refurbishment at its normal meeting place – Fellowship House. As in 2013, several members who were also members of the London Gardens Society did well in LGS competitions, with Diane Berger coming first and winning a cup in the best large back garden class.
2015 was a busy year, with a Seed Swap, a trip to Wisley, a talk by Dennis Lynch from Sunshine Garden Centre, and a trip to Borde Hill and High Beeches. The very popular Plant Sale was followed by the June Show, the Suburb in Bloom Garden Competition and Suburb Open Gardens. July began with a three-day visit to the gardens of Shropshire and Cheshire, followed in August by a trip to Capel Manor and Daisy Roots Nursery. The September Show was followed by a talk on Biddulph Grange the following month by Russell Bowes. Between all these events Committee members found time to encourage future gardeners in local schools to grow flowers and vegetables in their school gardens. Bulb-planting and miniature garden workshops were held in Garden Suburb Community Library in the Market Place for enthusiastic primary school-aged children. Other activities included helping with the planning and planting in the new Fellowship House garden and the contribution of floral displays to the St Edwards’s Church Flower Festival. Membership again stood at approximately 400.
In 2017 the National Gardens Scheme celebrated 90 years of opening private gardens across England & Wales for charity, and as part of the celebrations, Hampstead Garden Suburb Horticultural Society opened some of its most beautiful gardens for the NGS as a group for the first time on Sunday 25th June. As well as opening the garden gates of nine private gardens and one of the numerous allotment sites, there were home-made teas at Fellowship House and two professional nurseries sold seasonal plants in the garden. There was a treasure trail for children, and a raffle for the grown-ups! Maps were provided to guide visitors to the Open Gardens via the Suburb’s roads, twittens and woods. £5585 was raised for the NGS, the highest total for a London group opening in 2017.
