Plant of the Month: Pittosporum tobira ‘Neige du Mont Ventoux’ (May 2025)

This variegated Japanese Pittosporum — P. tobira ‘Neige du Mont Ventoux’ — is a lovely addition to any garden, and particularly courtyard gardens, where space is at a premium, as it is the perfect specimen for growing in a container.

It was at a rare plant fair in Kent many years ago when I spotted this very appealing shrub. It was “twinkling” at me so, naturally, I found I just could not resist it and brought it home! Because of its branched structure, it was placed in a terracotta container and there it has remained, contented, to this day. I hadn’t realised at the time though, that this variety is very suitable for a container, as its height and width is generally no more than one metre at maturity.

May 2025 Meeting and Show Table

There was a great turnout for the CABAHS May meeting, even after the exertions of the previous day’s Plant Sale! A small but beautiful range of items on the Show Table, from a cornucopia of Spring flowers to a single rose and a cactus. Congratulations to Kathy for winning this month’s ‘Best on the Table’ prize with a vase of Salvia, Cerinthe, Teucrium, Hesperis, Centranthus, Luzula and chives.

Pat’s 10 jobs for May 2025

1. Border irises are really doing their thing now and the show can be brief but make sure to keep the soil around their roots free of weeds so their rhizomes can bake a bit in the sun.

2. Time to Chelsea chop your tall perennials to stop them flopping later or to extend flowering. Good candidates are Phlox, Penstemon, Helianthus, Sedum/Hylotelephium – and I include vigorous Clematis too. You can either do the whole plant at once or just some stems to extend flowering, although it may result in smaller flowers.

3. Deadhead displays of pot plants like Violas to keep them flowering and stop them going to seed. Remember to give them a feed to keep the display going.

Fantasy garden tables

Those of you who are regular viewers of BBC Gardeners’ World will most likely have noted Monty Don’s table of potted plants, which varies throughout the seasons and looks like something most of us can only dream of! In a recent article by Alice Vincent, she describes what she calls Monty Don’s ‘Fantasy table’. (My latest garden fantasy? An elegant table covered in flower pots)

The scale of Don’s table and the amount he has displayed is something many of us may aspire to, myself included! On a recent visit to Anna L’s garden, I was impressed by how she had similarly grouped a range of plants in pots, a mix of bulbs, a small Phlox stolonifera, Violas, a Clematis waiting to be planted and a miniature Hosta. Anna very kindly listed the plants for me and you can see from this that a display does not have to be carefully curated, but a selection of whatever takes your fancy!

Narcissus ‘Thalia’ and N. ‘Pipit’; Clematis ‘Rising Star’ and C. ‘Bees’ Jubilee’; Pelargonium australe; Phlox stolonifera ‘Fran’s Purple’; Anemone de Caen blue-flowered; Primula ‘Stella Neon Violet’; Phormium; purple Viola; Hosta ‘Lemon Stiletto’

Keukenhof, April 2025

I returned to Keukenhof for a brief visit again this year. Transport in the Netherlands makes this a very easy trip and it is well worth making a stopover in Haarlem, which is a lovely town. I have little to add to the descriptions of my previous visits (April 2022, April 2023) so have just included a selection of photos which lovers of colour and tulips might enjoy!

What to look out for in the Old Pond Garden May 2025

Geranium pyrenaicum ‘Bill Wallis’

A member of the hedgerow cranesbill family, seen commonly in roadside verges – but what a star! It was named after Mr Bill Wallis, a passionate plantsman, who chanced upon the original seedling sporting electric violet flowers instead of the common pink hue. It is a low sprawling perennial which shows its vivid purple flowers from late Spring until late Autumn. Lovely ground cover for sun or shade. Resistant to drought and avoided by snails – what’s not to like!

Tiarella ‘Spring Symphony’ – Foam Flower

Enjoy a symphony of colour with this extraordinary Tiarella! A charming, shade loving relative of the Heuchera. In spring, slender stems rise above the leaves and hold a mass of pink and white starry flowers, giving a frothy effect – hence the common name the Foam Flower.

This variety has an Award of Garden Merit from the RHS and it copes in the difficult dry shade conditions under the Lime trees in the Old Pond Garden.

Spring Show 2025

A good time was had by all at our 47th annual Spring Show on Monday 14 April. A great turn out of members and several entries for each class – including a magnificent 18 Narcissus ‘Pipit’ pots!

In total there were over 90 entries in 14 classes – well done everyone. Thanks is due to all those who organised, set up, judged, prepared the flags / certificates and did the raffle and refreshments.

We welcomed horticulturalist Joe Woodcock to judge the classes* and he was full of praise for each and every entry. Joe interspersed his judgments with interesting facts, tips and growing advice on everything from the merits of deadheading to an explanation of the source-sink theory.

Pat’s 10 jobs for April 2025

1. Pinch out sweet pea plants above the third leaf to make bushier plants and then, as the shoots grow, pinch out side shoots in the same way.

2. Sow hardy annuals now like Nigella, opium poppies and poached egg plants in any bit of empty ground you may have and mark them so you don’t forget where they are. Many of these are excellent for pollinators.

3. Prune hardy Fuchsias now to stimulate growth by cutting back to just above a healthy bud which will prevent them from getting too woody.

4. Check Dahlia tubers for any growth and make sure they’re getting enough light by turning them round regularly towards the light.

March 2025 Meeting and Show Table

A packed library for the March meeting, and the first Show Table of the year – congratulations to Kathy for winning this month’s Best on the Table prize with her Narcissus ‘St Patrick’s Day’.

There was also a Plant Sales table and the usual raffle with lots of lovely plant prizes. The main event was a talk by Fiona Davison, author of ‘An Almost Impossible Thing: The radical lives of Britain’s pioneering women gardeners‘.

Plant of the Month: Camellia (March 2025)

During March, when the changeable weather still surprises us, it is wonderful to see the Camellias in flower, as they provide the much-needed WOW factor during the colder days – their profusion of flowers, colours, shapes and patterns add an immediate vibrancy and character to any garden or parkland.

In my neighbour Linda B’s garden, there are three Camellias but one stands out. The flowers are smaller and single, white (blush-pink as they age), scented and beautiful. The leaves are also different: matt-green and elongated and the overall appearance of the shrub is more elegant. It has grown, albeit slowly, and is now approximately 2’ in height. A plant app identifies it as possibly Camellia sasanqua.
