Ballota pseudodictamnus (2 litre pot)

Great for a sunny, well-drained gravel garden. Position: full sun Soil: poor, well-drained soil Rate of growth: average Flowering period: May and June Hardiness: fully hardy (borderline) Whorls of white or pink-tinted flowers appear in May and June on woolly stems above the mounds of yellow-flushed grey-green leaves. This upright, woolly-stemmed subshrub looks great in a sunny, well-drained gravel garden, surrounded by other drought-loving plants. Closely related to the 'false dittany' traditionally used for lighting oil-lamps in Crete, it may not survive in areas with cold, wet winters. Garden care: Cut back in early spring to retain a neat, compact shape. Avoid overwatering, particularly in winter.
