In the garden
Veronica teucrium 'Royal Blue' is a perennial member of the Plantaginaceae, native to the Grand Duchy of Luxembourg, valued for its summer display that runs from June to September. As a cultivar of Veronica, it suits temperate conditions and is mapped to H5 hardiness, meaning it is hardy in most parts of the UK. Place the plant in full sun or partial shade and avoid poorly drained sites; it needs well-drained soil with a moderate, steady moisture level rather than waterlogging. Positioning in free-draining soil improves flowering and reduces the risk of winter root problems. Routine watering while establishing is sensible, but heavy, constant wet soils should be avoided. Use Veronica teucrium 'Royal Blue' towards the front of a sunny border, in mixed perennial beds or gravelled areas where summer blooms are easily seen. Its June–September flowering period makes it useful for maintaining continuity of colour through the summer months; site it where that seasonal display can be enjoyed from paths or seating areas.
