No I posted it in the Houseplant forum. I have had it for over 20 yrs. If it is in the sun it gets purple streaks but it has never gotten totally purple.
It is in dark shade between a chair and table. We are thinking that maybe it is the chemicals in the pot. It is a cheap pot I picked up at CVS. But I have had it for 2 yrs and it has been planted with other annuals before and the plants that I planted in it last yr did not change colors.
It is used out doors. I would think if there was some chemical in the pot it would have washed out being in the elements for 2 years.
