Often described as plants with 'pillowy' leaves, these Columbian natives are low-maintenance and easy to grow. Give them bright light and allow the soil to approach dry between waterings. The average height of a mature plant is around 3 to 5 feet. Moreover, it spreads around 4 to 6 feet wide. These plants spread according to the space available. Thus, they get pretty immense in the wild. The plant has a rhizome, which grows horizontally along with the soil and produces foliage. The rhizome usually gets prominent and partially emerges out from the soil, after the plant gets about 1 meter tall.
