I purchased this strange looking bamboo plant solely because it looked so unique.
I am totally curious which species it could be, and why it grew a round ball shape on its stock.
The length of internodes is very small-maybe. 0.5 cm or smaller .
The leaves are and top stems are growing very quickly, and I'd love to see more of this neat, uneven growth pattern.
Can anyone help?
As mentioned in the comments, that's a Dracaena. Notice how the leaf scars are far closer spaced on the wide area. this is explained by a change in the growing environment during that time (likely increased light), causing closer leaf spacing and a more robust stem.
Not caused by the stem widening after hardening. To see more of this effect, try to move it to very bright light for a few months, then back to a lower light level for a while. When the leaves shed, you will notice patterns on the stem.
