Plant of the Month: Tree Peonies (April 2024)

One morning in mid-April – the warmest of the month so far, I had the pleasure of visiting our ex-chairman, Jillian S, to see the display of her stunningly beautiful tree peony flowers. These are well established shrubs with one or two still in bud and the rest nearly finished flowering, apart from the 2-metre species Paeonia delavayi, which is covered in red flowers and buds.

Every gardener should possess at least one tree peony – just to experience their few weeks of fleeting beauty – and, of course, their very handsome and large foliage, which is an added bonus to every garden for many months of the year.

I noticed that Jillian’s tree peonies have or had far more buds than mine, which is about 20 years old. Why is that? Jillian tells me that she has always had a strict policy upon purchasing any plant, including the tree peonies, and that is to immediately repot the plant with one-third multi-purpose and two-thirds of soil from her own garden. Only when the roots have established themselves in the new soil mix does Jillian then plant them in her borders. This method ensures there are fewer plant losses as the roots get the chance to adjust slowly to the change of soil, with the outcome being much stronger and robust root systems and, ultimately, stronger and healthier plants. And, that is the best gardening tip I have ever received!

Jillian tells me that all her peony varieties (Paeonia x suffruticosa) arrived as ‘freebies’ during 2009 and 2011, as special offers advertised in one of our major newspapers. They would arrive in good condition: an 18” stem with two or three branches and a sturdy root system of approximately 9” in length. These would, after potting on, be left for around 9 months to 1-year before being planted into a bed. In springtime, from then on, when the soil is still moist, a mulch of homegrown compost is added around the base of the plants to retain the health of these specimens.

Paeonia x suffruticosa possibly Huang Hu Huang Dao Jin

Paeonia x suffruticosa possibly Wu Long Peng Sheng

Over the years, Jillian has diligently and systematically recorded in notebooks all of her purchases. And in one of her notebooks she has found her notes on the exact dates the tree peonies arrived:
4th June 2009: Hai Huang Yao (yellow) and Huang Hu Huang Dao Jin (cerise with white splashes).
11th November 2009: Wu Long Peng Sheng (pink/red) and Honxia Hu Hong (pink).
23rd April 2011: Wedding Day.

Peonies prefer morning sun and dappled shade if possible and Jillian’s peonies are perfectly positioned, growing on the north side in the spring garden, some protected by the apple trees. Very little pruning is necessary but I notice that Jillian’s tree peonies are more elegant than my shrub, so a little judicious pruning on my part would not go amiss!

What to look out for in the Old Pond Garden April/May 2024

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.

The Woodlands Farm Cottage Garden

If RHS gold medals could be given to individual gardens, then The Woodlands Farm Cottage Garden deserves that honour. I am, at the moment of writing, sat on one of the many benches enjoying this charming garden.

Volunteers started working to create a cottage garden back in 1998 and now, 25 years on I am gazing at their ‘gold-medal’ creation. The garden has everything one would want: wide gravel paths edged with brick or logs meandering around several large informal flowering beds; a rose and clematis-framed timber pergola walkway; glasshouse; summerhouse; raised vegetable and fruit beds; propagation area; pond; a bug hotel; and, very importantly, tables and chairs for family snack times.

Beds in the Woodlands Farm Cottage Garden

A wren has announced its arrival on the beautifully pruned Exochorda and children and mothers are coming in to excitedly explore and admire the garden’s loveliness. From my bench are carefully pruned shrubs arising tall from the spring beds. This allows visitors to clearly view the purple honesty, inky-blue aquilegias, mauve vinca, forget-me-nots, narcissi, tulips, camassias, allium buds, geraniums, hellebores, wallflowers, bergenia, primulas, lamiums and more – all looking their very, early-spring best. Masses of tall cow-parsley are breaking into flower in front of the flowering choisya and viburnums, creating an harmonious effect. And I’ve spotted purple-stemmed cow parsley looking extremely healthy, as well (most envious!)

Seat in the Woodlands Farm Cottage Garden

This cottage garden is sheltered and faces south. It is surrounded by mature trees and many evergreen shrubs so it has its own little micro-climate.

Before I leave, I glance once again at the charming, delicately-pink blossom on the spreading branches of the old apple tree. With a table and chairs set beneath its canopy and spring flowers in the foreground, it is a really lovely vision. And it’s a gold-medal from me! The garden is open to the general public. More information about Woodlands Farm Trust here. Do visit before the spring flowers fade.

Spring Show 2024

Congratulations to all our entrants, spectators and winners at our 46th annual Spring Show! Despite lots of comments like ” I have nothing left, the snails have had everything” it’s clear CABAHS members rise to a challenge as we had 80 entries in total. Monday evening was a great opportunity to show off our collective gardening skills, as well as have another little trip down memory lane about Shows of the past.

Floral display — The Pipit competition – a definite challenge this year!

Birds-eye view of the show — The Pipit competition – a definite challenge this year!

Kathy covered the origin of the Spring Shows at last year’s meeting, with the first one held in 1978, and as a result of that research we resurrected two new classes – a Primulas & Auriculas class and a Baking class. They were well received, with 5 and 8 entries respectively.

Mention has to be made of Mandy’s wonderful shortbread shapes – the wheelbarrow filled with chocolate earth was apparently Brownie’s contribution!

Pat’s Jobs for April

1. Prune hardy fuchsias now both in pots and in the ground to promote new growth and to prevent the plants from becoming too woody.

2. Plant out pot grown sweet peas now making sure to pinch out the shoots to promote bushy plants. You can also sow directly in the ground now if you didn’t sow earlier but watch out for slugs munching new seedlings.

3. Someone said the other day that they hadn’t cut back their clematis but I don’t think its too late as the growth on them is phenomenal. It just means they will flower a bit later but then that extends the season.

The View from my Window

The small patio is shielded from the sun, in a south facing garden, by an Acer palmatum ‘Katsura’. The tree caught my eye while on a trip to Kent. Must have one of those I thought. The sapling was bought and is now well mature. Some of the limbs show signs of viral attack, but it soldiers on.

Early to leaf, in February, the leaves are green and red. It produces sap, which attracts the aphids. With the aphids, the small birds make regular visits to eat the goodies. The birds include Blue, Great and Coal Tits, Robin and Goldfinches. The Dunnocks also pay a visit, foraging in the growth below, together with a variety of bees including the distinctive yellow faced variety. Soon after, it will produce a vast amount of blossom, and after that very small sycamore-like seeds. In time and onto autumn, the leaves go from yellow to orange and then fall, covering all the surrounding ground.

What to look out for in the Old Pond Garden: March and April 2024

We hope you enjoy a spring walk around the walled gardens at Charlton House! Look out for:

Forsythia

Forsythia is in the olive family, renowned for its vibrant yellow flowers which appear in spring, long before the leaves unfurl. The one by the Charlton House stables is quite old and we are not sure of the exact variety. We pruned it back hard a year ago and it seems to have loved it!

Cherry laurel (Prunus laurocerasus)

Prunus laurocerasus (cherry laurel) in the Old Pond Garden, Charlton House, March 2024

A ‘background’ evergreen plant most of the year, but quite striking when the white candle flowers appear in Spring. Although we call it a laurel, it actually isn’t – it’s in the cherry family! We know that an early resident of Charlton House, Elizabeth Puckering, introduced cherry laurels to the gardens. She was friendly with the diarist John Evelyn, who lived in Deptford at the time, and exchanged cuttings with him in around 1654.

Daffodil (Narcissus ‘Thalia’)

A fragrant and vigorous trumpet daffodil which is now in it’s third year in the walled gardens, so has formed some nice big clumps. It starts off creamy yellow and fades to white, and is sometimes referred to as an orchid daffodil. For fans of BBC Gardener’s World on TV, you might recognise it from Monty Don’s writing garden!

Siberian bugloss (Brunnera macrophylla ‘Jack Frost‘)

Brunnera macrophylla 'Jack Frost' (Siberian bugloss) in the Old Pond Garden, Charlton House, March 2024

Brunnera has lovely heart-shaped, silvery-veined leaves that look as if frost has touched them. The leaves light up shady areas of the garden. It has long lasting, bright blue flowers that look very much like forget-me-nots, and which provide lots of nectar and pollen for visiting bees.

Wood spurge (Euphorbia amygdaloides var. robbiae)

Euphorbia amygdaloides var. robbiae (wood spurge / Mrs Robb's Bonnet) in the Old Pond Garden, Charlton House, March 2024

Wood spurge is in the Euphorbia family, so take care! If the stems are broken, they gush with a thick milky latex substance that can cause blisters on skin. They are handsome perennial plants, shade loving, with zingy lime-green flowers in late Spring and rosettes of glossy dark green leaves. Another name for this plant is ‘Mrs Robb’s Bonnet’ – we would like to see the hat that inspired that name!

Still going strong, winter into spring!

Lenten rose (Helleborus orientalis)

Helleborus orientalis (hellebore / Lenten rose) in the Old Pond Garden, Charlton House, February 2024

The Lenten Rose is a perennial flowering plant and is part of the Buttercup family, so not a rose at all! Its common name comes from the fact it usually flowers between Ash Wednesday and Easter – the period known as Lent. Hellebores (Lenten roses) can be white,

Primrose (Primula vulgaris)

Primula vulgaris (primrose) in the Old Pond Garden, Charlton House, February 2024

We grow the English or ‘common’ primrose in the walled gardens, which is the natural pale yellow one that gives its name to the colour Primrose. It is often one of the earliest plants to flower in Spring (the Latin word ‘prima’ means first). Early butterflies like the Brimstone benefit from its nectar. Plants will hybridise (cross) very easily with the garden bedding Primulas that come in lots of different bright colours, so seedlings can come up a surprising colour!

March flowers on display in Frilly's Tea Room

Pat’s Jobs for March

1. I sowed my sweet peas early in the month five seeds to a 3 inch pot and then placed them on a light window sill or greenhouse if you have one. They don’t need bottom heat and I don’t soak or nick the seeds but of course you can if you wish. Keep turning the pots so they don’t all lean towards the light.

2. Remove browning blooms from camellias to keep the display going especially the white ones which never seem to drop their spent blooms. I just wish I had room for more as they’re such a cheerful sight.

Batley Park, The Standard, London, SE3

The residents of London, SE3 and SE7 are treated to a two-month spectacle every year when the spring bulbs burst open beneath the London Plane trees in their local green space, called Batley Park.

Batley Park consists of a triangular space at the heart of the south-east London shopping centre, known as The Standard, surrounded by the busy, one-way B210 road.

During the winter, the park comes alive with the thousands of purple, mauve and white crocus sprinkled amongst the green sward, followed quickly by swathes and swathes of yellow daffodils, glowing like bright lanterns in the soft sunlight. It’s mother nature’s tapestry and a lovely sight to behold.

Crocus and daffodils among the trees in Batley Park

The park’s existence is all due to local campaigners, including The Rev John William Marshall, in the late 19th century, unhappy about the appearance of their village green. At that time it was known as Sheepgate Green, and due to their determination the space was transformed. Trees were planted and railings installed and thus renamed Batley Park, after the philanthropist, William Fox Batley, who contributed to the improvements. In 1889 a final touch was added – a Memorial Fountain was included on the south-west corner of the park. If you have not yet seen this year’s spectacle, do visit the park whilst visiting The Standard. At the time of writing I noticed that the daffodil clumps were still producing buds so that means local residents can enjoy this display for a few more weeks.

March flowers shared by Members

We are always keen to hear about how member’s gardens are growing or about what you can see from your window but occasionally we receive shorter messages. So here are a few we’ve had recently.

Angela thought members might like to see a photo of her Amaryllis lily. She says “Their sale in supermarkets at Christmas has rapidly become a tradition. Their very decorative, over the top flowers people either hate or love. I love them. They are easy to grow and spectacular. I planted mine after Christmas and it has now produced amazing flowers.”

Viv sent us a photo of the first tulips of the year in her garden with some other pots. Unsurprisingly, she is getting excited about spring…
