'Gollum' has a stout succulent, segmented, branching trunk, it can be shaped to create spectacular bonsai forms. Leaves are tubular, trumpet shaped, each of them tipped with a "suction cup", 4-ranked (decussate), smooth, deep glossy green in color with very light spotting usually with bright red leaf margins; the new growth is red. Blooming in mid-winter through spring, the flowers are clustered, small, star-like, white or pinkish-white, with pink stamens.
Succulents require porous soil with adequate drainage, and bright light with ample airflow. Water thoroughly when soil is dry to the touch. Protect from frost.
