@digitalrn Thanks,Rickk. I thought it fascinating too. I have never noticed this from these plants before. I think I have always trimmed them back before they got to this point!
@grammyn Very! Wen we were in Vegas at end of summer break (boy I miss the free time I had then!) I went to Bodies exhibit. This pic looked like the exhibit of the blood vessels...they ran some fluid thought them and it hardened, then they took flesh off and had a system of arteries like this....
