Red Hot Pokers

I have about 6 Red Hot Pokers in the back yard...one is about 6 years old the others are about 2 to 3 years old. They get sun in the morning and filtered sun for half the day, only one flowered (the eldest) Is the position wrong do you think? Do they need more sun to flower? They are very healthy, the rest being much bigger than the mother plant. Oh, I did move them to different parts of the garden.

 

Shaz, if they are healthy then they are doing fine. To encourage flowering next year , start feeding with a high potash fertiliser now.:thumb:

 

Thanks again David. Will do
