Teucrium hyrcanicum (ht 70 cm) is an interesting perennial plant from Iran and countries nearby: it has a low basal clump of deep green textured foliage and long spires of purple spires during mid to late spring. It thrives in very dry conditions and enjoys sun: though I have one blooming quite well in a partly shaded spot. I enjoy seeing it partnered with plants that have leaves with a purplish tinge or underside, such as some of the Cape Angels Plectranthus cultivars and Tradescantia pallida 'Purpurea'. I cut it right back after flowering. It does self-seed quite determinedly but so far, I wouldn't call it a nuisance. It belongs to the Lamiaceae family of plants.
Flowers in October, November, December.
