Melilotus officinalis (yellow melliot) 9 cm Pot

Growth habit & appearance: Melilotus officinalis forms upright stems clothed in fine, trifoliate leaves and long racemes of soft yellow blossoms with a characteristic sweet-hay aroma. In its second year the plant reaches full stature, producing generous flowering spikes rich in volatile coumarins. Its light, airy habit adds a vertical accent while retaining an unmistakably wild-meadow texture.

Growing conditions: This hardy biennial performs reliably in Irish conditions, especially in full sun and well-drained mineral soils. Although native to parts of Europe, it naturalises easily in temperate climates and tolerates the cool, damp variability typical of Ireland. Plants grown in our Co. Clare nursery transplant well when set out in spring or early summer. Once established, they show good resilience and require minimal intervention through both seasons of growth.

Traditional & herbal uses: Modern herbal literature highlights Melilotus officinalis for its coumarin-containing aerial parts, which are examined in peer-reviewed studies for their role in supporting venous tone, mild lymphatic congestion, and tissue comfort. Current use also includes interest in its soothing properties for haemorrhoids, minor swelling, and tension-related digestive discomfort. 

Maintenance & harvesting: This biennial’s first year focuses on root and basal growth; flowering begins in year two. Keep young plants weed-free to prevent competition and allow the stems to develop fully. Harvest the aerial parts during peak bloom on dry days, taking care not to bruise the tissue, as this accelerates coumarin release. Cut plants back after flowering if you wish to limit self-seeding. Dry material in thin layers with good airflow to prevent mould and excessive heating.
