Exotica Purple Waffle is a small perennial tropical plant with an unusual texture that is native to Asia and belongs to the Acanthaceae family. One of the main features of the plant is that it changes its color to a duller color when it needs watering, which makes it popular and desirable not only among beginners but also among experienced collectors.
Hemigraphis alternata 'Éxotica' is easily identified by its oblong-oval leaves that have a waffle texture and are dark green above and purple below. The leaves grow on long slender stems up to 24 in (60 cm) long, but the plant itself only grows to 8 in (20 cm) tall, making it quite compact.
The small flowers appear in early summer and are bright white in color, but they are not as showy as the colorful leaves and are not popular.
