I have been growing some okinawan sweet potatoes in tropical greenhouse conditions all winter.
Its a root crop not actually related to the potato or to the yam.

After 6 months the plant is still healthy and a few feet tall.
I want to harvest some potatoes, and ill cut off some root nodes from the current plant and replant the current plant...
But should i also sprout one of the sweet potatoes to get me plants that are "new" and not "old"? Or will the plant basically keep propagating forever from its root nodes and slips?
As a perennial i assume it can go for several years, but i dont know if it has an age limit to be aware of.
