Alecost

Alecost, also known as Costmary, is a traditional 'heritage' herb that was once a staple of the English garden but is now less commonly seen. It is a hardy perennial that forms a spreading clump of large, oblong, serrated leaves with a unique fragrance—a mixture of mint and balsamic sweetness. Historically, it was used to flavour ale (hence the name) and as a 'Bible leaf' bookmark, as its scent was said to keep people awake during long sermons. In late summer, it produces small, inconspicuous button-like yellow flowers on tall stems. It is very hardy (H7) and will grow in most UK garden soils, provided they are not overly wet. It can be quite vigorous and may need a bit of space or regular division to keep it in check. The leaves can be used sparingly in salads or for infusing teas. It is a wonderful plant for those interested in historical gardens or looking for a tough, unusual groundcover with a nostalgic scent.
