Strobilanthes Explained

Strobilanthes is a genus of about 350 species[1] of flowering plants in the family Acanthaceae, mostly native to tropical Asia and Madagascar, but with a few species extending north into temperate regions of Asia. Many species are cultivated for their two-lipped, hooded flowers in shades of blue, pink, white and purple. Most are frost-tender and require protection in frost-prone areas.[2] The genus is most famed for its many (but not all) species which bloom on long cycles of several years, such as Strobilanthes wightii which blooms every thirteen years.[3]

Species

Strobilanthes atropurpurea is a temperate species, native to eastern Siberia; it is cultivated for its purple flowers.

Strobilanthes dyeriana (Persian shield) is a tropical plant native to Myanmar. It is grown for its dark green foliage with bright, metallic-purple stripes radiating outward from the central leaf vein. In proper conditions, it will also produce pale purple flowers. Persian Shield grows best outdoors in USDA zones 9 and 10, although it can survive in other zones as a houseplant given sufficient temperature, soil moisture and humidity. It has gained the Royal Horticultural Society's Award of Garden Merit.[4]
