Tell me what lighting you have it in.and have you had any drastic temp changes?This plant will show change at most changes in enviroments,but recovers most times.3-4 inch tips root easily just getsome thats just getting the woodyness to it.
Mines in bright light in the shade.it mostly gets summer rainfall& if seems dry I'll water it.I about cooked it in june the 1st two days we had temps in the 90s.I took a cutting and moved it in deep shade and watered& freshened soil and has perked back up.
I've let mine flower
once....cause read that it will.I don't care for the flower
and it started turning the leaves greener so like the purpleishness better.I sowed the seeds
and they grew,gave the pot away.I keep tips pinched for more bushyness and to keep vines off ground(water splashing turns foliage brown)
