I have several Malabar plants growing, all the red/purple stem variety. Plants look great and healthy. In south Texas, so very hot in June. Plants are in containers so I water twice a day on average. They are only about 2 months old, but are already producing the little (flower?) pods that will become seeds. I fear the leaves may become bitter, like lettuce and regular spinach that has gone to bolt. Is this normal for Malabar?
