January 2026 talk: Clematis for every season

On Monday we welcomed Everett Leeds who gave us an amusing and highly informative talk about the prolific world of Clematis. He has been involved with Clematis for many years through growing, speaking and writing about them. He has been the Chairman of the British Clematis Society four times and is co-author of The Illustrated Encyclopaedia of Clematis . Everett’s enthusiasm for the genus was highlighted when he shared a photo of his former home with the front fence, hedges and trees completely swamped by a 120 foot long and 40 foot high ‘monstrous’ C. Montana. After cutting this completely away, he planted another!

January 2026 Meeting and Show Table

Our first meeting of 2026 welcomed Everett Leeds as our speaker. A Clematis expert, Everett gave an entertaining talk and also sold seeds of some of the Clematis he discussed.

As usual, members enjoyed refreshments, took part in the raffle, shared their garden-related resolutions for 2026 and, of course, there was the regular Show Table. Six members took part with a wide variety of entries. We hope that as Spring gets going more members will be keen to show off and share their plants that are looking good each month.

Pat’s 10 jobs for January 2026

1. If you can brave the cold and wet it’s time to winter prune that Wisteria by cutting back all long whippy branches to within two buds of the main framework, so you can shape the plant for flowering.
More information on Wisteria pruning, including a video, from the RHS.

2. Any form of mulch is good on the soil now, in the form of your own homemade or bought compost, or even leaf mould if you have it. If you can’t face lightly forking it in, the worms will do it for you.

New Year flowers in Members’ Gardens

Following on from the New Year’s Day Flower Count in Charlton House Gardens, several members did their own Flower Count, and reported some surprising (and not-so-surprising) discoveries.

New Year's Day flowers in Ali H's garden (Chaenomeles, Geum, Hebe, Primula) — Japanese quince, water avens, elephants’ ears, Geranium, winter jasmine, Mexican fleabane, Viburnum bodnantense, Hebe, primrose, Salvia ‘Amistad’, Cyclamen coum, rose, brown-eyed Susan, Mexican orange blossom and laurustinus in Ali H’s garden

New Year's Day flowers in Ali H's garden (Bergenia, Geranium, Salvia, Cyclamen) — Japanese quince, water avens, elephants’ ears, Geranium, winter jasmine, Mexican fleabane, Viburnum bodnantense, Hebe, primrose, Salvia ‘Amistad’, Cyclamen coum, rose, brown-eyed Susan, Mexican orange blossom and laurustinus in Ali H’s garden

The winter-flowering shrubs were of course out in force (Camellia, Jasminum nudiflorum – winter jasmine, Skimmia japonica, Viburnum – both V. bodnantense and V. tinus, Clematis ‘Freckles’ and Daphne odora), as were the hellebores (though mine have remained resolutely in bud with not a single one opening yet!). Mandy A’s Loropetalum (Chinese witchhazel) was in flower, as were several people’s Hebes. My Chaenomeles japonica (Japanese quince) was covered in fruits, but still producing the odd confused flower too, along with a nearby Geranium macrorrhizum and Geum rivale.

New Year 2026 Flower Count at Charlton House Gardens

On a perishingly cold day – encouraged by a wintry sun – the intrepid Garden Volunteers ventured out on their mission to spot which brave flowers are showing off in the gardens this new year, 2026.

Viburnum tinus at Charlton House — *Viburnum tinus*

This is the third year we have undertaken a flower count, so we should know roughly what to expect. UK weather data shows that 2025 was the sunniest on record, and probably the warmest too. Here in the depths of winter, it’s easy to forget the unprecedented spring sunshine and incredibly hot summer that we’ve had. This is bound to have disrupted plant lifecycles and confused some into flowering at the wrong time.

January 2025 Talk: Succession Planting for a Long Season

Our first meeting of 2025 was very well attended. The speaker and the topic obviously attracted a good audience. The Show Table received a good selection of displays, with Jean’s a worthy winner of Best on the Table.

Our speaker, Fergus Garrett, the highly influential plantsman and horticulturalist, has been Head Gardener at the internationally acclaimed Great Dixter Garden in Northiam, East Sussex since 1993 and is the CEO of the Great Dixter Charitable Trust. He gave an excellent, wide-ranging talk on how to keep our gardens looking vibrant and spectacular all the year round. He explained how to plant for a long flowering season with plants co-existing in one place, but performing at different times. He used photographs of the spectacular gardens at Great Dixter to illustrate his points. He said Great Dixter had the advantage of scale and greenhouses but it is possible to scale down what they do at Great Dixter and use their scheme in our own gardens with minimal labour.

He particularly used the magnificent long border at Great Dixter as an example of how to plan a long flowering season. How to use structural under-planting, interlaying and interplanting with bulbs, self-sowers, perennials, clumps of bedding plants and climbers.

Plant of the Month: Daphne (January 2025)

In the bleak midwinter, in amongst the primroses and snowdrops, the New Year brings excitement as the Daphne shrubs come into flower. For one member, several are looking looking extremely handsome and are, at present, the highlights in her garden.

Daphne odora 'Perfume Princess' behind Astellia — Daphne odora ‘Perfume Princess’ behind Astellia

Daphne odora ‘Perfume Princess’: This evergreen to semi-evergreen variety was bred in New Zealand and is considered the most perfumed of all the Daphnes. Between January and March, this shrub, which is regarded as hardy (although it suffered from the recent heavy frosts) will send out pale-pink blooms amongst its upright, handsome foliage, reaching a height of 1-1.5m over the years. Our CABAHS member says it has “wonderful scent and made a showy plant in just a few years.” I note that there is also a variety Daphne ‘Perfume Princess’ White on the market that would be a bonus to any garden.

Pat’s Jobs for January 2025

1. Prune Wisteria this month and next by taking all side shoots back to 2 or 3 buds. Very old plants may need severe pruning to show off the flowers.

Very tangled wisteria waiting to be pruned — Very tangled Wisteria in need of pruning!

2. Start pruning roses in earnest although some are still unbelievably flowering. Remove any foliage with blackspot and don’t compost. Old roses respond well to hard pruning so don’t be afraid, removing all dead and dying wood and cutting stems back to above a bud.

3. I had to remove dead Clematis shoots from a Daphne Jacqueline Postill and in doing so pulled off some of the flowers so take care and do it soon if you can. But leave the main prune until next month.

New Year Flower Count 2025 at Charlton House

Another cold start to a new year allowed the volunteers to take a step back from gardening and undertake a second survey of plants in flower at Charlton House. This had been done at the beginning of January 2024 and it was interesting to compare during a gentle walk round on 9th January 2025. At first glance there seemed to be little flowering. Making a thorough search with fifteen of us, along with Jason, we found many that were on last year’s list as well as some unexpected interlopers.

January 2024 Show Table

Well done to CABAHS members who managed to find something to display on the Show Table in the depths of freezing January, it was lovely to see. Congratulations to Sian for winning this month’s Best on the Table prize with her camellias.
