About the Group

The Hardy Geranium Group was formed in 1974 when interest in the plants was booming. There are now approx. 110 species and 600 cultivars in British gardens. They range in height from a few cm. to 1m. and in colour from white through pink, mauve and pale blue to deep magenta, violet and blue. There is a geranium for every site in the garden: hot and sunny or dry shade. Margery Fish famously said “When in doubt, plant a geranium.”

We are still the only association dedicated solely to this large family of garden-worthy plants, which have been voted the Hardy Plant Society’s favourite flowers. Our members provide advice and information about the plants to gardeners, nurserymen and journalists in the UK and abroad. Membership is open to all members of the HPS and we welcome those who are not specialists but would like to know more. 

We produce two newsletters a year in Spring and Autumn, host an annual AGM and Geranium Day at different venues around the UK, and organise a geranium and erodium seed exchange each year (free to members).  The seed list is usually sent out in November. You can find full information below on how to join at the beginning of the 'Further Information' section.


The Hardy Geranium Group has two zoom talks up and coming.

Geranium Day 2021

Geranium Day 2021 will be held on Saturday 26th June at Wrest Park, Silsoe, Bedfordshire in the morning, then at Trevor Hards’ beautiful garden in Clophill in the afternoon.  The event is fully booked.  We will provide a full report of what we’re sure will be a very enjoyable day.

Geranium Day 2020 - please note this has been cancelled. 

A message from our Chairman, Tricia Newton:

I am very sorry to advise you but Hardy Geranium Day is being cancelled this year.

Having taken advice the committee has decided that the uncertainty of the current Coronavirus situation, we have to put the welfare of our members first.

It is very disappointing and I expect that, like me, you were looking forward to Julie Richie’s talk and seeing two lovely gardens. I hope we will get the opportunity to visit Sue Clarke at some point in the future.


We have now arranged for Julie Ritchie of Hoo House Nursery to give a talk using Zoom on Thursday  29th April at 7pm . 
The title is 'Geraniums and Friends'

2019 Geranium Day Report - South Petherton and East Lambrook Manor Gardens, Somerset

On a bright sunny June day Tricia Newton, our chairman, welcomed HGG members and friends to our 45th anniversary celebrations at South Petherton and East Lambrook Manor.  There were lots of plants for sale, especially geraniums; we enjoyed excellent presentations from Andrew Norton and Mike Werkmeister; and our visit to East Lambrook Manor gardens in the afternoon certainly lived up to expectations.  A good time was had by all!

Jan Vaughan, chairman of the Hardy Plant Society and an HGG member, gave a warm speech about the HGG, and quoted memorably from Beverley Nichols' book 'Merry Hall': "Well I love geraniums, and anybody who does not love geraniums must obviously be a depraved and loathsome person."  And so say all of us!

Andrew Norton owned East Lambrook Manor for 14 years from 1985, Mike Werkmeister is the current owner.  Their talks were fascinating.  Andrew's main themes were the history of the garden, the previous owners and East Lambrook's plants both before and during his time there.  Mike focussed more on Margery Fish.  When Margery and her husband decided to move from London to the countryside, East Lambrook was one of the first properties they saw.  It was not love at first sight but, luckily for us, they eventually returned and bought it.

East Lambrook's beautiful garden owes much to Mark Stainer, the current head gardener.  He started work at East Lambrook in 1985 at the age of 14 and has been there ever since – a successful career many would envy.

2018 Geranium Day Report - Great Kingshill, Buckinghamshire

Members arriving at our 2018 geranium day were greeted by a long table full of hardy geraniums on sale, many of which are hard to find. Our members often keep the less common cultivars going when nurseries give up on them and there was a brisk trade at the sales table during the day.

Margaret Stone, our chairman for 10 years, stood down at the AGM and Tricia Newton, a former committee member, volunteered to take over the reins. Margaret was presented with a watercolour of Geranium macrorrhizum ‘Bevan’s Variety’ as a token of the group’s appreciation for her hard work in running the group and organizing many of our geranium days. Hardy geraniums seem to be less fashionable now than they used to be but this group is still the main source of information on Hardy Geraniums in the UK and is uniquely able to educate and inform the general public, and probably able to answer questions better than any other similar group. Margaret also gave a talk on “Garden Worthy Geraniums”, giving us lots of ideas and recommendations about which varieties are likely to do well, based on her many years’ experience of growing them in  Worcestershire.

The garden visits were to Barry Street's garden and allotment, followed by a visit to the Plant Specialist nursery in Great Missenden.  Barry has a typical-sized suburban garden which is packed with plants including many interesting geraniums, peonies and hostas. The Plant Specialist nursery was also excellent with a garden area at the top of the nursery (all plants being well labelled) and a large well-stocked nursery area, providing more buying opportunities.

As one member said “An excellent day, in the true tradition of HPS, returning home fired with ideas and enthusiasm, and knowing a lot more than when you set out in the morning.”
