What to look out for in the Old Pond Garden: March 2026

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

Daffodil (Narcissus ‘Elka’)

Narcissus 'Elke' in the Peace Garden at Charlton House

A fragrant, small and early-flowering daffodil, you can spot Narcissus ‘Elka’ spreading gently in the Peace Garden. It has pale petals and a creamy yellow trumpet. The name ‘Elka’ comes 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 irritation. 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!

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.
