This plant thrives by producing an abundance of side shoots, quickly forming a lush, bushy appearance.

Additionally, the trimmed shoots can be easily replanted, quickly developing new roots and flourishing. This plant is an ideal background plant and will fill out empty spaces in no time, making it a great choice for beginners.
