Teucrium hyrcanicum - IRANIAN GERMANDER ("PURPLE TAILS")

Perennial  with long purple-red spikes. Reminds of Veronica, but is more heat and humidity tolerant. Slightly aromatic leaves deter deer and rabbits.

Medicinal used in the past -  respiratory troubles,digestion, and an anti-inflammatory use. Essential oil offers antimicrobial properties.

Usually not super long-lived (all depends on the drainage), but will persists by moderate self-seeding.

Best in sunny garden and drained soils.

Blooming Time: usually July/August to early September, with the peak in full summer
Size: 1.5-2' tall tall x 0.75-1' wide, stays in clumps. Partially evergreen, depending on your zone.
USDA Zones: 5-9, but hardiness is influenced by the drainage, with sharp drainage probably hardy to zone 4/5
Culture: sun, half shade, prefers drained to well drained soil with average moisture (medium) to medium-dry. Established plants are drought tolerant. Average, sandy, rocky, gritty soils. Avoid waterlogged soils! 
Moisture Needs: medium (average), medium-dry to dry. We do grow it quite successfully on a bit heavier soils, that were amended with coarse sand.
Origin: Iran, Caucasus
Deer/Rabbit Resistant: yes / yes
Attracts Butterflies or Pollinators: we haven't fully trialed it here in Indiana, but since it is Mint family plant, flowers should attract bees (native and honeybees) and possibly some butterflies. Definitely pollinator friendly plant.
Attracts Hummingbirds: possibly yes , we need to verify this summer
