Rosemary

Rosemary, Ellen McHale/RBG Kew Salvia rosmarinus

The aromatic, sun-loving rosemary is a prized Mediterranean herb.

It is unsurprising that rosemary is otherwise known as the 'wonder-herb'; it has an array of uses from adding flavour to cooking and fragrance to perfumes, to decorating sunny garden borders and even improving memory.

Rosemary has been a symbol for memory for hundreds of years. In Shakespeare's Hamlet, Ophelia says: "There's rosemary, that's for remembrance".

Rosemary is a fragrant, evergreen shrub with needle-like leaves and two-lipped, purplish-blue and white flowers. New growth is soft and flexible but older stems become woody and form trunks with time.
