Alexanders

Smyrnium olusatrum, commonly known as Alexanders, is a robust biennial or short-lived perennial, often found in coastal areas and old gardens in the UK. It forms large clumps of glossy, dark green, celery-like leaves, typically reaching 60-120cm in height and spread. In spring, it produces large umbels of bright yellow-green flowers, followed by black seeds. Alexanders thrives in full sun to partial shade and moist, well-drained soil, often tolerating coastal conditions. Hardy to H7, it can self-seed freely. The young shoots, leaves, and flower buds are all edible, offering a rich, aromatic flavour, reminiscent of celery and parsley.
