This giant catmint from Spain and Portugal is perfect in our dry summer areas where it will thrive with little attention. Large fleshy spikes of mauve-blue flowers are held above the clumps of soft felty leaves. Great to colour a dry garden and simply stunning when mass planted below old roses. Adored by bees.
Plant in full sun in an enriched, free-draining soil. Tolerates dry periods once established. Avoid waterlogged or wet soils.
