Ballota nigra (Black Horehound) Herb Plant


Some Herbs may be too tall for our standard packaging and will be trimmed to fit. This will not be detrimental to the plant but will mean that these herbs will flower later in the year.

The Blister packs used to protect our beautiful herbs during transit are made from 100% recycled plastic and can be recycled kerbside.

Black Horehound (Ballota nigra) Herb in 1 Litre Pot 

Black Horehound is not very often grown these days but it is useful if you have an area that is particularly impoverished. It will flourish in poor dry, soil for example along the edge of driveways and other neglected areas. The only threat to horehound is to sit in very wet conditions over winter. Horehound is a hardy perennial of the mint family — with its telltale square stem — and, like most mints, can become invasive if not controlled.

This hardy perennial can grow to 60cm - 1m tall, producing wrinkled green leaves adorned with small hairs, this is a bushy plant and it will produce rings of small purple flowers from June to September in the second year of growth. It is native to the UK and as such is bee and butterfly friendly.

The leaves may be cut for use or drying in the first year. 

Herb Usage

Ancient herbalists prescribed Black horehound for a number of conditions, though is not widely used in modern herbalism because of its unpleasant flavour. It is reputed to be  an antiemetic, and was also often used for treating problems connected with the respiratory system, convulsions and  low spirits. The fresh herb is sometimes used to make a syrup. We would recommend this plant for use in a wildlife garden particularly if you have an impoverished poor dry area you wish to fill.
