Yellow Ribbed Melilot (Melilotus officinalis) is a native UK wildflower known for its tall, upright stems and bright yellow, fragrant flowers. This perennial species is well-suited to a variety of habitats, including meadows, grasslands, and roadsides. It thrives in fertile, well-drained soils and is particularly valued for its ability to improve soil health due to its nitrogen-fixing properties.
The plant’s yellow flowers, which bloom from mid-summer to autumn, are highly attractive to pollinators such as bees and butterflies, making it a beneficial addition to any wildflower mix. Yellow Ribbed Melilot is also a hardy, low-maintenance plant that supports biodiversity and provides a valuable resource for wildlife in both rural and urban landscapes.
