Ballota flowers and Marrubium
UK Horehound flowers
There are two different kinds of Horehound in the UK – Black Horehound Ballota nigra and White Horehound Marrubium vulgare. Although the name sounds exotic, I found that it only refers to the plants downy (hoary) nature.
Black horehound – Ballota nigra
Black Horehound is common in South East England and I don’t have many photos of it as it is often a scruffy plant. It has purple flowers.
This plant seen on Seaford Head was definitely scruffy!
White horehound – Marrubium vulgare
I hadn’t heard of White Horehound until 2021 when it was pointed out to me by Chris at Seaford Natural History Society. I understand that it’s quite rare in the UK. However we were in Crowlink Sussex where there is a known colony.
White horehound – Marrubium vulgare has it’s own page.
