In the garden

Veronica teucrium 'Crater Lake Blue' is a perennial member of the Plantaginaceae, introduced from the Grand Duchy of Luxembourg. It produces its main display through the summer months, flowering from June to September, so it should be considered where a reliable summer presence is wanted. Give it a position in full sun to partial shade with well-drained soil and a moderate, even level of moisture; avoid sites prone to waterlogging. If your soil is heavy, improve drainage with sharp grit or by planting into a raised bed. Mulch lightly in spring to conserve moisture, but keep the root collar clear of deep mulch to maintain free drainage. In a UK garden it sits well in sunny mixed borders, gravel or scree areas and in containers placed on a sunny patio. Because its main season runs from June to September, use it to link early-summer and late-summer flowering perennials in the border so the bed retains continuous interest through the peak months of bloom.
