Euphrasia officinalis subsp. pratensis, commonly known as Meadow Eyebright, Eyebright, Large-Flowered Sticky Eyebright, or Common Eyebright, is an annual herb native to grasslands, meadows, and pastures across Europe. It typically grows to a height of 0.1-1 feet (0.03-0.3 meters) and features small, lanceolate leaves. The flowers are white or purple with yellow variegations and a prominent lower lip, blooming from late spring to early autumn. The flowers are modest in size but can be quite showy due to their abundance and attractive coloration.

Meadow Eyebright is valued for its traditional use in herbal medicine, particularly for eye-related conditions, hence the name "Eyebright." It is also appreciated for its delicate flowers and ability to attract pollinators such as bees. In cultivation, it prefers full sun to part shade and thrives in a range of soil types, including clay, loam, and sandy soils, provided they have medium drainage. While it requires medium amounts of water, it can tolerate periods of dryness once established. Meadow Eyebright is not commonly used in large-scale horticulture but can be found in wildflower mixes and naturalistic plantings. It is relatively low-maintenance but can be susceptible to powdery mildew and rust.CC BY-SA 4.0
