Propagating from Cuttings
Another way to propagate Asystasia coleae Rolfe is through stem cuttings. Take a stem cutting, around 4-6 inches long, from a mature and healthy plant. Remove the lower leaves and dip the end of the stem in rooting hormone. Plant the cutting in well-draining soil and keep it moist. Place the cutting in a warm, bright, and humid environment till new growth develops.
Propagating from Division
Asystasia coleae Rolfe can also be propagated through division. During the growing season, carefully lift the plant from the soil, and separate the root ball into smaller sections with a sharp, sterile knife. Each section should have a healthy root system and some stems and leaves. Immediately replant the new divisions in a well-draining soil mix and keep it moist until new growth is established.
Propagation of Asystasia coleae Rolfe is relatively straightforward, and with proper care, this plant can be grown easily in a tropical or subtropical garden.
