Veronica chamaedrys aka Germander Speedwell

Veronica chamaedrys, or germander speedwell, is a low, creeping perennial. It belongs to the plantain family, Plantaginaceae. Its native range runs from Europe to Siberia and Central Asia. It is native to Britain and Ireland. This temperate plant grows in grassland, woods, and hedgerows. Other names include bird's eyes, blue stars, and angels' eyes.

The plant forms mats and roots where stem nodes touch soil. Its garden height ranges from 0.3–1.6 feet [0.1–0.5 metres]. Its spread falls within the same range. Plants reach full size in one to two years. The leaves are oval, with pointed tips and toothed edges. Hairs cover the leaves, and the foliage dies back each year. Two lines of hairs run along each flowering stem. These stem hairs help distinguish the plant.

Bright blue flowers rise in spires in spring and early summer. Each flower has a white centre and four lobes. The blooms measure up to 0.03 feet [0.01 metres] across. They bring small patches of blue to mixed lawns. The flowers also draw pollinators to these spaces. This makes the plant useful in wildlife gardens and wildflower meadows. Woodland edges and hedgerows also suit its natural style.

Grow it in sun or light shade, in moist soil that drains well. RHS lists clay and loam as suitable soil types. It accepts acid or neutral soil. Plants can grow in exposed sites or sheltered spots. Although it prefers moisture, RHS also records drought resistance. Its RHS hardiness rating is H7, the coldest category listed. Plants For A Future gives USDA zones 3–7. Growers can raise new plants from seed. The plant needs no pruning.

Aphids may attack the plant. Possible diseases include downy mildew, fungal leaf spots, and fungal rot. Phytophthora and, at times, honey fungus may also cause trouble. Plants For A Future does not flag it as weedy. That source gives its food value a low rating. The leaves have served as a substitute for tea. It records no known hazards, rather than proof of safety. It also records past use for skin complaints and wounds. Leaf infusions once had a role in treating coughs and asthma. These are reports of traditional use, not evidence that such treatments work.
