Buck's-Horn Plantain

Buck's-horn plantain (Plantago coronopus), sold under the variety names Herba Stella and Minutina, is an annual-to-perennial cool-season leaf vegetable in the family Plantaginaceae. Its deeply toothed, antler-like leaves form a flat rosette with a tender, mildly nutty flavour prized in Italian cuisine. It tolerates light frost and poor soils, making it exceptionally easy to grow in Nordic gardens. The plant self-seeds freely once established, returning year after year with minimal intervention.

Growing

Direct-sow once soil reaches 5 °C, pressing seeds lightly into the surface and covering no deeper than 0.5 cm — light aids germination. Space plants 15 cm apart; thin gradually as leaves develop. Successive sowings every three to four weeks extend harvest. Seeds can also be broadcast in a cold frame or unheated greenhouse for very early crops.

Care

Water regularly during dry spells, but avoid waterlogging — the plant is tolerant of dry, sandy or poor soils. No feeding is required in reasonably fertile soil; on very poor ground a single application of balanced liquid fertiliser after thinning is sufficient. Remove any flowering stems promptly to keep the rosette productive; allow a few plants to bolt if self-seeding is desired.

Harvest

Begin harvesting outer leaves individually once the rosette reaches 8–10 cm across. Cut the whole rosette 2 cm above the crown and it will resprout for multiple cuts. Leaves are ready when they are a deep green and still tender; avoid harvesting yellowed or very large leaves as they turn bitter. The plant remains harvestable until it bolts or hard frost kills the crown.

In the kitchen

Use raw leaves in salads and grain bowls where their mildly bitter, slightly nutty flavour contrasts well with sweet dressings. Wilted briefly in olive oil they work as a side vegetable in the Italian tradition. Chop finely into herb butters, risottos or omelettes, or use whole small leaves as a garnish.

Storing

Wrap unwashed leaves in a damp cloth or place in a closed container lined with paper towel and refrigerate for up to five days. For longer preservation, blanch briefly, dry thoroughly and freeze in portions. Leaves do not pickle well but can be blended into frozen herb oils.
