Cordyline plants - Hawaiian Ti plant

I have 3 Cordyline plants in the front garden, two green cordylines and one "Red star" and they was growing lovely until last years winter hit them hard and with this summers heat the Red star leaves went dry and then new shootings was coming off each one and they never flowered although they reached 6ft in height, so I had my hubby cut the stems across, knifed out some of shoots from the stem and then left so many to each stem for good maturity and they're coming on great.

My back garden green cordyline is now doing a new shooting also but that's still nice and healthy.
