What to look out for in the Walled Gardens: September 2024

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

Night moth Salvia (Salvia nachtvlinder)

Salvia 'Nachtvlinder' in the Old Pond Garden, Charlton House, September 2023

With velvety plum-purple flowers, this Salvia is attractive to moths and other pollinating insects and flowers over a long period – well into late Autumn.
It has deliciously blackcurrant-scented leaves and is said to protect roses against black spot when it is planted under them. A large clump is now happy in the Peace Garden.

Michaelmas daisy (Aster x frikartii ‘Monch’)

Aster x frikartii 'Monch' in the Old Pond Garden, Charlton House, September 2023

A bushy perennial with clusters of yellow-centred, lavender-blue daisies that flower right through the Autumn, it is very attractive to pollinators. One of the most reliable and popular Michaelmas daisies (so called because they flower at the time of the feast of Michaelmas on 29 September), it was bred by a Swiss nurseryman called Frikart and named ‘Monch’ after a Swiss mountain.

August 2024: Gardeners Question Time

An entertaining and informative evening was had at this year’s Gardeners Question Time. As usual, it enabled members to get advice on their gardening problems, and to air their gardening frustrations. Chaired by Sir Nicolas Bevan, the CABAHS President, the panel also comprised Tom Brown, the Greenwich Park’s Head Gardener, and Pat Kane, a long standing CABAHS member.

Most of the questions were sent in by members beforehand. They covered a broad range of gardening areas and problems: growing hollyhocks; aphid control; tree size; cistus, salvia and sisyrinchium pruning; how to grow dahlias; what killed my rose; problems with apple trees and rambling roses; how to encourage children to get involved in gardening; recommending a fertiliser for yew hedges; the cause of curly cucumbers; dealing with self seeding; and problems with bamboo.

The Sunk Garden at Great Dixter House and Gardens, East Sussex

Christopher Lloyd loved colour, and as I stand on the upper pathway of the Sunk Garden, here at Great Dixter, I notice the pops of colour from the spires of pink-purple Lythrum and terracotta-orange Crocosmia all around me.

Designed by Nathaniel Lloyd, Christopher Lloyd’s father, after WW1, this south-facing and sheltered sunken garden is enclosed by two barns, a magnificent yew hedge and a wall on the southern boundary, thus creating its own micro-climate and the plants love it!

Plant of the Month: Agapanthus (August 2024)

One of the nicest aspects about walking around the streets in our neighbourhoods is being able to view the diverse range of flowering trees, shrubs, perennials and bulbs that enhance front gardens and, in early August, it’s the showiness of Agapanthus that makes one stop in one’s tracks in admiration.

And so, it was an added pleasure to be able to admire the magnificent evergreen Agapanthus praecox “Madeira Blue” and “Madeira White” in my neighbour’s rear garden. Linda tells me she purchased the bulbs in Madeira approximately ten years ago, where these perennials have become naturalised throughout the island.

Agapanthus 'Madeira Blue' and 'Madeira White'

The plants are extremely tall and vigorous and absolutely stunning, with additional flowering stems this year, having outgrown (and broken) previous terracotta pots. The bulbs have been in the existing plastic pots (sitting on feet) for the past three years, having been divided up – no easy task – and planted into several more containers. They have not been fed for a while and are not given protection in the winter (it’s a sheltered garden) with the flower heads left on until spring.

Pat’s Jobs for August 2024

1. It is especially important to keep Camellias and Rhododendrons damp at the roots this month as this is the time that the buds form for next Spring. Water well and mulch if you can.

2. Take Aeonium cuttings now by severing leggy leaf stems a couple of inches below a cluster. Leave the stem end to callous over, then push into gritty compost and keep in a shady spot until roots start to form.

Fans of Clivia miniata

Angela B wrote: “Clivia (or Natal lily, originally from South Africa) is one of my favourite plants. It comes in a variety of colours. I have been growing Clivia miniata, the orange-flower variety, for years. Its glossy leaves and bright orange trumpets are striking and decorative. It has flowered well this year and I thought members might like to see it, and I encourage those who have not grown one to do so.

It’s easy to grow. See the RHS website for detailed care instructions. It’s a woodland plant and likes indirect sunlight and regular watering from Spring to Autumn, but minimal watering over the winter.”

We asked a few other members about this unusual and lovely plant. Chris B is also a fan of them, she says hers has beautiful flowers in May and June and she puts it outside for a holiday in the Summer (although not in full sun). She brings it back inside for winter and reduces the watering.

July 2024 Meeting and Talk: The Savill and Valley Gardens, Windsor Great Park

John Anderson has a very distinguished horticultural career. Trained at Kew, he has been head gardener at a range of famous gardens, and his contribution to horticulture was recognised in the award of the RHS Veitch Memorial Medal. In 2016, he became Keeper of Windsor Great Park Gardens, part of the Royal Estate, and managed by the Crown Estate.

It was a particularly interesting and informative talk. The gardens are unusual, situated as they are in a Royal Estate of 8000 acres, and Windsor Castle being a world tourist attraction. Yet the gardens and their management are less well known to the public. John Anderson showed a range of photographs of the gardens, described their history and development over the decades, and the challenges they now present.

The challenges include managing people whether they are tourists, cyclists or picnickers; dealing with vandalism and littering; and protecting its historic landscapes. Also the problems of climate change: evidenced in its Long Walk tree avenue, at over two miles the longest in Britain, where elm and horse chestnut were succumbing to disease, to be replaced by more resistant species such as ginkgo (Maidenhair) trees.

Picnic in the Park: Teddy Bears Picnic 2024

If you went down to the park yesterday, we hope you had a big surprise, for all the ‘bears’ were gathering there together because.. of the Teddy Bear Hunt!

Thank you to all who came and donated or supported this fun event, and to all the (over 100) children who found the ten hidden Teddies and worked out the name of the Charlton House Teddy to get their treat. (It had to be Newton Bear of course, named after Sir Adam Newton, who built Charlton House). But what a huge range of ‘teddy’ soft toys came along for their photo-opportunity! (please post your pictures to #charltonhouseteddy).

And of course huge thanks to our volunteer/resident Artist who made the “Ted Head”, a brilliant attraction for both young and old!

The promised lovely weather was marred by a short rain-burst in the middle of the day to freshen everything up and make the picnic-ers dive for the Old Library, but it was only for 5 minutes and everyone came out again. We are so well used to it this year! The day was not only for the children, the gardens were looking particularly fine, with 35 different flowers in bloom.

A successful day and a lovely community event with collaboration between the Royal Greenwich Heritage Trust, the Garden Volunteers, Charlton Library, Charlton Toy Library and Frilly’s cafe. Thank you!

Teddy Bears 2024: If you go down to the Old Pond Garden, you’re sure of a big surprise..

If you go down to the Old Pond Garden this Saturday, you’re sure of a big surprise. For every teddy that ever there was, will gather there together because, today’s the biggest floral count ever!

If you have ever wondered which month is the most floriferous in the Old Pond Garden, I’m guessing it’s July. We are expecting lots of visitors this Saturday July 20th, 11-3, for the Teddy Bears Picnic, and they are in for a treat (as well as a picnic) as we have counted over 30 plants out in full flower. Can you spot them all? We will have an info board out so you can match names and flowers, while the kids are charging about finding the hidden Teddies. Works for all ages.

The Teddy Bear trail will be in the Old Pond Garden and there will be lots of photo-ops for you and your teddy with the lovely garden backdrop. See you there, better come in disguise!

White Garden, Sissinghurst Castle

In all the years I have been visiting Sissinghurst Castle, I have never seen the White Garden look so lush; it was a ‘sea of white fluffiness’ and its loveliness took one’s breath away.

The White Garden is an enclosed garden, laid out in a formal pattern, with clipped borders of box framing brick herringbone pathways, punctuated by box cubes. These features provide structure and act as a framework and a contrast to the white flowers and grey foliage within their boundaries.

The focal point is the central gazebo, which is covered by the highly fragrant white rambler rose (Rosa mulliganii) – now finished flowering but later in the year produces rose hips. Beneath sits a maroon-coloured waist-high urn (1930s), planted with Thumbergia alata (a cream-coloured Black-eyed Susan).
