Plant of the Month: Iris (May 2024)

The show gardens at the Chelsea Flower Show each May just zing with the stunning colours of the irises in bloom and they really are one of the main attractions (apart from roses) that are on display. Being ‘show-stoppers’, their impact allows the designers to then infill and arrange around them the more delicate flowers and foliage to an harmonious effect. Visitors admire, with ‘oooh’s and aaah’s’ at the soft, subtle shades and again, of the deeply-rich and vibrant colours of each and every iris grouping.

The name Iris means rainbow and in Greek mythology ‘Goddess of the Rainbow’. The petals and roots of several species, including Iris germanica (bearded) and Iris pallida (Dalmatian/Orris root) are used in the beauty industry, in the manufacture of perfumes, lotions, in food such as spices and even added to gin. Seemingly, the dried root, after 3 years, has the aroma of violets. This industry goes back to the ancient Greeks, Romans and Egyptians and probably long before their time.

I have an Iris pallida flowering in my front garden, low-growing, which is highly fragrant. This was kindly given to me by Penny S some years ago. The flower is fading so unfortunately not worthy of a photograph but it certainly should be grown, as the variegated grey-foliage blends nicely with neighbouring plants. I wouldn’t be without it.

My number-one favourite, though, is Iris ‘Langport Wren’, a Kelways‘ introduction from 1973 and deservedly worthy of the RHS Award of Garden Merit. It was flowering in my front garden until a few days ago when the slugs/snails chomped its head off! The fragrance is reputedly of orange and chocolate – but I wouldn’t know as I haven’t had the chance to find out!!! The first photo below is of this delectable flower, a painterly amalgamation of browns, purples and russets, growing in Margaret T’s garden.

Spring in Cornwall

I have just spent a very happy week at Duloe Manor, a complex of self-catering holiday apartments and cottages near Looe in Cornwall. The main house was built in the 1690s for the Rectors of the local church. The whole complex is set in lush gardens of around three acres: a few mixed beds contained lovely combinations of saxifrages, irises and other familiar perennials while in less formal areas, swathes of wild garlic provided backdrops for beautiful pink campions as well as English bluebells in full bloom. In the car park several banks of pale yellow primroses remained stubbornly but delightfully in flower! Majestic rhododendrons provided splashes of magenta and purple.

Pat’s Jobs for May

1. It’s a good time to take softwood cuttings of both tender and hardy perennials such as pelargoniums, anthemis and penstemons. Place in a shady spot until roots begin to form.

2. Put plant supports in place to stop things flopping and make them yourself from shrubby prunings or just push prunings in the soil around the plant.

3. I’ve Chelsea chopped my phlox today and also done a few clematis as they are far too tall and leggy after all the rain we’ve had.

Centre for Wildlife Gardening

28 Marsden Road SE15 4EE, Open Sunday to Thursday inclusive, 10.30 to 16.30. No charge

We are members of the London Wildlife Trust, which runs the Centre for Wildlife Gardening (CWG), but it was word-of-mouth from a volunteer at Christchurch Community Garden that made us aware. We visited on London Marathon Day, passing through a crowded Blackheath Station on our way to Peckham Rye Station.

Marsden Road itself is remarkable: its houses all along have designer ironwork gates & railings on wildlife themes, and each lamppost has a ‘squirrel’ high above. These, and the wildlife-themed iron gates to CWG, were designed by Heather Burrell: bollards at the entrance and within were designed by Antony Gormley: a gable-end has a large mural of a Goshawk.

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.
