Persian shield, Bermuda conehead
Persian shield isn’t Persian. It’s from Myanmar (Burma). It is not found in the wild in North America. The genus Strobilanthes means “cone flower,” because the flowerheads are conical.
Identification: Persian shield is an evergreen, or more accurately, an “everpurple,” given that its leaves are a stunningly beautiful shade of purple, variously described as iridescent or metallic. It is a tropical shrub 3-4' (91-121 cm) tall and 24-36" (60-91 cm) around. Leaves are opposite, a combination of purple and green, and 4-7" (10-17 cm) long. Flowers are inconspicuous, pale violet, on short cone-shaped spikes.
