Plant of the Month: Bergenia emeiensis

I have a choice plant in my garden which, amazingly, I have managed to keep alive all these years and it’s all thanks to Margaret T, who kindly gave me an off-shoot such a long time ago.

To make sure it was protected, I planted this bergenia in a pot on the shady side of the steps, so that the plant would stand out and not get damaged. It flowers every winter and has been flowering all through February this year and the elegant white, nodding flowers are still hanging on, fading to a shade of blush-pink. The rhizomes have outgrown the pot now so I will be thrilled if I can return the favour and offer Margaret T an off-shoot of this beautiful plant. Plants are difficult to obtain but I understand seed might be available on the market.

The botanists and growers regard this species as the most elegant of all the Bergenias and I can see why, as this compact plant with its rosette of neat, oval, apple-green, shiny leaves enhances the dainty flowers, which are held aloft on elegant, often blush-pink stems.

Seed was first collected from the limestone cliffs in Sichuan in the Himalayan mountains in 1935 and again in 1982 by Roy Lancaster who introduced the species to the UK. Cambridge Botanic Garden website mentions that Bergenia emeiensis can be seen growing in their Alpine House and that they are also trialling the species in their woodland area. The plant used to be regarded as tender but I regard it as a hardy perennial in my small courtyard garden which, like many London gardens, has its own micro-climate. Even so, I do, unfortunately, sometimes lose plants during colder winters but this species has not yet been damaged and so it’s a great treat to be able to admire this handsome specimen from my kitchen window.

The View from my Window

A piece inspired by Kathy’s entertaining post.

I, too, have a comfy seat looking out on my garden where I spend many happy hours deciding what changes need to be made in my garden (there is always something).

I am currently enjoying watching my pots of bulbs grow and begin to flower. I posted a photo on Facebook of my Harmony irises and my friend in Norfolk (who I think was rather envious) suggested I had a microclimate in my garden. It is very sheltered and faces west so maybe I do.

I have just decided to empty my rather unsightly compost bin and replace it with a smaller, more discreet one. I therefore have a large pile of compost which I am in the process of shovelling around the garden. I am expecting a spectacular display later in the year!

My Clematis Armandii under the tree is budding nicely. I planted it some years ago and was disappointed last year that I had so few flowers on it. That was until I looked out from the upstairs window and discovered that my neighbours were enjoying a beautiful display! It had put all its energy into growing to a lighter spot in the garden next door!

I find this time of year quite difficult garden-wise, especially when the weather is mild, as it is at the moment. I am having to restrain myself from going wild with the secateurs and cutting everything back. I shall wait another month before giving my clematis, roses and salvia a good hair cut. I think it is also time to give the Hibiscus Syriacus Woodbridge a trim as it has grown rather tall and thin.

I hope other people will write about their views, as Kathy suggested.

Anna’s Visit to the Tibetan Peace Garden, Geraldine Mary Harmsworth Park, Lambeth

After the busyness of a visit during half-term to the Imperial War Museum, it was relaxing to visit the adjacent Tibetan Peace Garden on an amazingly warm and sunny, winter’s day in February.

This is a lovely, partially enclosed garden which was opened by the Dalal Lama in 1999 and it was named ‘Samten Kyil’, meaning the Garden of Contemplation and this is exactly what the designers have achieved.

The garden is made up of two parts: an outer garden of trees and lawn sweeping around and enclosing the inner circular garden, the whole bordered by a circular pathway in which to enjoy the views. White-barked Himalayan Birches, making a striking contrast against the green and blue of the grass and the sky, are interspersed with Weeping Cherries and Prunus serrula (Tibetan Cherry) with polished, red-purple bark.

Pat’s 10 Jobs for February…

1. Prune Group 3 clematis (late flowering viticella types) now by cutting all stems back just above a leaf node starting from the ground up. Don’t be timid as they respond well. Then feed around the plant base with an organic feed making sure to avoid emerging shoots and mulch with compost.

2. If you have some, mulch your beds with homemade compost or leafmould. If you don’t have enough just mulch around your favourite plants.

Plant Of the Month: Lonicera fragrantissima (Winter Flowering Honeysuckle)

If you want to lift your spirits on a cold, grey, winter’s day, then this is the plant for you!

At the Tibetan Peace Garden, adjacent to the Imperial War Museum, on an amazingly warm and sunny February afternoon, I was greeted at the entrance by the beauty and fragrant flowers of an often underrated winter flowering shrub.

The creamy-white-pale yellow, tubular flowers with protruding stamens often appear on bare or semi-evergreen stems and in my garden they literally flower for months, from November-December through to March-April. I can view the masses of flowers from my kitchen windows which is a visual treat but really, it’s my neighbours who benefit from the spectacle and fragrance as the shrub is situated on the boundary wall.

At the Tibetan Peace Garden, the shrubs are situated in full sun and their 2×3 metre spread on either side of the entrance pillars acts as a welcome into the garden enclosure and also indicates they are absolutely loving their perfect, sun-soaked, location.

What to look out for in the Old Pond Garden: February 2024

We hope you enjoy a Winter walk around the walled gardens at Charlton House! This month, look out for:

Snowdrop (Galanthus nivalis)

Galanthus nivalis (snowdrop) in the Old Pond Garden, Charlton House, February 2024

The Latin name for snowdrop is Galanthus, meaning ‘milk flower’. They hang their heads to keep their pollen dry for the winter insects they are adapted to attract. When temperatures reach 10C the outer petals open up and this is the temperature at which winter pollinators like bumble bees can fly! Snowdrop sap contains natural antifreeze which allows them to recover quickly after a frosty night. People who collect snowdrops are called Galanthophiles and they pay huge prices for rare varieties.

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, pink, purple and green and they cross with each other very easily so all sorts of colours can result. We are trying to keep to the pink ones in the Old Pond Garden and the white ones will go in the Glade.

Silk tassel bush (Garrya elliptica)

Garrya elliptica (silk tassel bush) in the Old Pond Garden, Charlton House, February 2024

This is a vigorous bushy evergreen shrub with silvery-grey leathery leaves, originally from California USA. It is hardy but grows best in a sheltered spot so it loves the Walled Gardens. The male plant has wonderful catkins in Winter/Spring that look like tassels – look closely at the tassels, they have an amazing structure. The female plant is less commonly seen (we don’t have one here) but produces purple/brown fruits in summer.

The View from my Window

Vija and Anna started these great posts about the view from their windows, and I thought I would add my bit. Really, in these cold, grey days of winter, it’s a bit odd that I should find the view from my window at all exciting. We have big patio windows which are unforgiving at this time of year and expose everything in the garden: the ragged border edges, uneven lawn, leaning obelisk (Storm Henk!) etc. But I can sit in my comfy chair looking out and now the leaves are all gone I can see all the way to the end fence..

…and I can Plan.

When I say I can see the end fence, this is because we took out a row of 20 ft high Leylandii trees last October. (Did we buy the house with them, I hear you ask? No, I actually planted them, one of those teeny gardening mistakes surely anyone can make..?) The idea behind getting rid of them is that it will let lots of light in, when next we have any. The stumps have been left, as I couldn’t face a stump grinder trolling through the house, so I need to Plan some sort of feature around them. (Maybe a birdbath on top of one..!)

A bonus is that for years and years I had been piling leaves and cuttings out of the way under the trees – so I am now left with some truly gorgeous compost! A little silver lining.

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.

Pat’s 10 jobs for January…

To be honest it has been so wet and now so cold that the ground is frozen but if conditions return to normal maybe you can try some of the following…..we live in hope!

1. Today according to the RHS is National Houseplant Appreciation Day so try giving those houseplants some attention and if they’re not looking good, treat yourself to a new one checking you have the right conditions for it.

2. Remove old hellebore leaves right back to the base to show off their flowers and to stop any leaf spot or other diseases from spreading.

3. All my violas in my front window box have died and a good gardening friend reminded me it could be vine weevil larvae chewing the roots which I haven’t had for ages so turn out the window box and check for those grubs and replace with fresh compost.

4. Start pruning roses cutting back with a slanting cut to above a bud and use the resulting prunings for cuttings 6 to 12 inches long and insert into either a pot or the ground so that 2/3 of the cutting are below the soil. They take a good while to root but its worth the free plants if they root.

5. Winter prune wisteria by cutting back shoots to 3 or 4 buds from the main stem.

6. Cut back really tatty herbaceous plants but leave anything with hollow stems or stems and foliage that may harbour overwintering insects. I started cutting back a bay tree until I saw the ladybirds amongst the stems.

7. Seed potatoes can be chitted from now on by placing them so they don’t touch in boxes, egg cartons are ideal, and placing in a light frost free place. Don’t forget to label the variety.

8. Prune established soft fruit bushes such as gooseberries, red and white currants removing any dead wood and cutting back main shoots by a quarter. If grown as a bush aim for a goblet shape with an open centre to aid air circulation.

9. Look at your seed catalogues and order anything you especially want before they run out.

10. Make sure to have some scented flowering shrubs either in the garden or in pots for pollinators to include winter honeysuckle, sarcococca, daphne and viburnham and aim to plant some by your door so you can catch the scent.

Happy gardening all!

Plant of the Month: Iris unguicularis (Algerian Winter Iris)

As much as I love this perennial and have planted many clumps over the years, I find it struggles in my clay soil. My now, one-and-only plant, obviously needs more sun and perhaps lighter soil, as it has flowered perhaps only once this winter and that was on 23rd November, when I took the photograph below. But Margaret T’s winter irises have been really putting on a display, with her two clumps producing 2-3 flowers at a time, on and off since December. And these will carry on flowering well into March. I’ve seen them flowering profusely when nestled against sunny, front elevations, in poor soil. But in Margaret T’s garden, the soil is rich from regular additions of compost and manure and you can see by her photograph that she has healthy, plump plants.
