Some type of sinuosus?
This plant has finger-sized plump green stalks with no spikes.
There are clusters of green leaves at the top of each stalk and some brown hairs on its sides. The guy who sold it to me at the market said it was a sinuosus, but this doesn't really look like the pictures I'm finding online of phyllobolus sinuosus.
Could it be something else?
Thanks for your help!
Wow, Vanessa - that is one crazy looking character! I almost said it's celery.
I do believe that this guy is Senecio, which can be grown as bonsai, which makes sense from the thick stems.
Here's some more on this page; Senecio so maybe check through the entries there.
You can see more about a similar plant here on Daves Garden Website.
Hope that helps!
