Plant(s) of the Month: December flowers

What a mild 2025 December we are having! So mild, the weather is confusing some plants, such as lavender, Calendula and yellow-flowered Phlomis, out in flower at present.

One of the joys of winter is admiring all the window boxes, the wide variety of beautiful Christmas door-wreaths and observing what’s flowering in front gardens whilst out strolling.

What to look out for in the Old Pond Garden July 2025

Penstemon ‘Garnet’ – Beardtongue

Although at its peak in July, this has been out since May and is one of the longest-flowering plants in the Old Pond Garden. At the moment we really love it for it’s drought tolerance – no need to water this one! It has dainty, tubular flowers which insects with long tongues like bumblebees can enjoy, and it provides both pollen and nectar for visiting insects. Prefers a sunny spot but will do well in part shade too, so you can spot it in several of the beds. It is a semi-evergreen, only losing it’s leaves in the very depths of winter.

Dianthus carthusianorum – Carthusian Pink

Another lovely drought-tolerant plant that we don’t have to water! It must be in full sun to flower well, so it just loves the gravel garden in the central bed of the Old Pond Garden. It’s a perennial, forming bigger clumps each year and giving that great “pop” of colour. A gentle self-seeder and long season in flower.

What to look out for in the Old Pond Garden June 2025

Phlomis italica – Balearic sage

This is an evergreen shrub in the mint & sage family, native to Spain, which has lovely woolly grey-green leaves (touch them!). The hooded pale lilac flowers are beloved of pollinators, especially bumble bees. The ones in the front beds at Charlton House are humming with buff tailed bumble bees.

Phlomis russeliana – Turkish sage

Phlomis russeliana

Another one in the mint & sage family, but this is not a shrub, it is a herbaceous perennial (so it drops it’s leaves in Autumn but comes back the next year). 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 and provide shelter for insects in winter. It gently self-seeds – we have been potting them up so look out for them in a future plant sale!

What to look out for in the Old Pond Garden May 2025

Geranium pyrenaicum ‘Bill Wallis’

Geranium Bill Wallis purple flowers

A member of the hedgerow cranesbill family, seen commonly in roadside verges – but what a star! It was named after Mr Bill Wallis, a passionate plantsman, who chanced upon the original seedling sporting electric violet flowers instead of the common pink hue. It is a low sprawling perennial which shows its vivid purple flowers from late Spring until late Autumn. Lovely ground cover for sun or shade. Resistant to drought and avoided by snails – what’s not to like!

Tiarella ‘Spring Symphony’ – Foam Flower

Tiarella

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.

What to look out for in the Old Pond Garden: March 2025

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

Daffodil (Narcissus ‘Elke’)

Narcissus 'Elke' in the Old Pond Garden at Charlton House

A fragrant, small and early-flowering daffodil, you can spot Narcissis ‘Elke’ in the Peace Garden. It has pale petals and a creamy yellow trumpet. The name ‘Elka’ is apparently from a combination of the names of two ‘lady daffodil growers’: Elizabeth and Kate.

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!

New Year Flower Count 2025 at Charlton House

Another cold start to a new year allowed the volunteers to take a step back from gardening and undertake a second survey of plants in flower at Charlton House. This had been done at the beginning of January 2024 and it was interesting to compare during a gentle walk round on 9th January 2025. At first glance there seemed to be little flowering. Making a thorough search with fifteen of us, along with Jason, we found many that were on last year’s list as well as some unexpected interlopers.

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.

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

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)

Phlomis, or turkish sage

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’)

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!
