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

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

New England Aster (Symphyotrichum novae-belgii ‘Violetta’)

Aster flowers Oct 24 , Charlton House Old Pond Garden

‘Violetta’ is a spectacular New England aster, which for a couple of months from late summer, bears a prolific display of violet-purple daisies. A naturally tall plant, it provides a regal purple splash of colour – long after many other perennials have finished flowering. Our plants are originally a donation from CABAHS member Anne.

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.

Moth Night at the Old Pond Garden 18/19th September 2024

Jason Sylvan, Head Gardener at Charlton House, has designed the Old Pond Garden to be as attractive to wildlife as possible. Because we talk about monitoring moths, he asked if we could check how many moths are visiting the garden. We should have tried this in the warmer months when there are more plants in full flower but we had missed that for this year so we gave it a shot on a warmer dry night in September to test out a strategy.

As we wrote in an earlier post, we have been monitoring moths for the Garden Moth Scheme since 2013 in Newcastle-upon-Tyne and since 2019 in Blackheath. The moth trap is a box with a light (our type gives off no heat), and below the light are two panels of see-through Perspex, one each side and shallowly angled down, with a slot/gap between them. The moths ‘funnel’ into the box, and it’s difficult (but not impossible) to get out. Inside are egg-trays, which provide resting places.

Why do moths fly towards the light? Until recently, the correct answer has been that nobody knows, but researchers in Sweden found the answer: for aeons, light at night was above and dark was below, so moths orientated themselves to fly with their backs to the light above. In artificial light – fires, candles, street lamps – they still try to fly with their backs to the light, circling round and round, and sometimes become disorientated.

The trap is placed before sunset, and collected at sunrise the next day. So an early start.

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.

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!

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

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

Turkish sage (Phlomis russeliana)

A herbaceous perennial in the Mint family, native to Syria and Turkey. The name ‘Phlomis’ comes from the Greek word meaning ‘flame’. Heart shaped leaves of some species were used as lamp wicks in ancient times. The stiff upright stems carry yellow flowers, which look good as seed heads in winter and provide shelter in winter.

Woodland sage or Balkan Clary (Salvia nemorosa ‘Caradonna’)

A bee magnet because it offers both nectar and pollen, this a hardy herbaceous perennial with dazzling violet flowers. Susceptible to slugs and snails sadly, but luckily we don’t get too many of those in the Old Pond Garden.

Catchfly (Silene armeria ‘Electra’)

Silene armeria 'Electra' in the Old Pond Garden, Charlton House, June 2023

Blue-grey leaves and hot pink flowers for weeks on end. An annual which self-seeds prolifically. It is called catchfly because there is a sticky area on the stems just below the flowers, which greenfly and small insects get stuck to. Feel it gently with your fingers!

May Plant Sales 2024

May is the month for plant sales! We held two this year, our big annual one was held at Charlton House on Saturday May 18th, along with the Blackheath & Greenwich WI and a select group of other market stalls. The plants were all set out in the Peace Garden which is not only a lovely setting but also meant we didn’t have to carry them too far! Visitors started queueing outside the gates before we opened at 10, aiming for a bargain and a bit of horticultural conversation.

People buying plants — Peace Garden 10.05 am

Our plants had mostly sold out by 12.30, which was a bit sad for latecomers. But volunteers were on hand to chat about the gardens and Stella presented her findings about the history of the garden in the Old Library.

We also had a “Bugs in the Beds” trail for the little ones and Frilly’s was open all day.

Plant Sale, Cakes, Trails, Tours, Talks!

Date for your Diary: Saturday May 18th from 10am

Preparations for our annual Plant Sale are well under way and it’s shaping up to be a GOOD DAY! The Garden volunteers have been potting up for weeks and CABAHS members have been sowing, taking cuttings and splitting their prized perennials. We will have a lovely selection for sale. They are not garden-centre plants – they are better, because we know how well suited they are to our local conditions!

The WI bakers have also been busy, and promise their usual delectable display of cakes. There will be other market stalls too and Frilly’s will be open for drinks and snacks.

For the kids, we have a “Bugs in the Bed” discovery trail around the Old Pond Garden, with a prize if (when) they solve the puzzle.

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.

Bunnies in the Beds 2024

Our “Bunnies in the Beds” Easter Trail took place on Saturday (April 6th) for the fourth year running, it is becoming a fabulous fixture of the Garden Volunteers year. We start thinking up mad ideas in January during tea breaks, then gradually whittle them down to create an exciting but practical trail.

This year, the Bunnies went on an egg hunt with a difference! Having found all the eggs they then had to match them to their parent animal, in order to collect a prize. And by the end of the day, 175 children had achieved their goal. There were birds eggs to find of course, but also frogs, snakes, sand lizard, moths and even a dinosaurs egg!

Also on offer: Potting Up Table with free seeds, courtesy of RHS Britain in Bloom which is celebrating its 60th anniversary this year. We were not expecting this to be so popular and almost ran out of seeds! So many small gardeners-in-the-making came to this event, it was lovely. If you are growing your seeds on, you can keep track how others are doing on social media on @RHS GrassRoots and #RHSBloom60.
