11 years ago we brought 25 Pohutukawa trees from a native tree wholesaler in Te Hana. They have never flowered. We live on a mountain range outside of Warkworth and we can see both coasts of NZ. Is there something wrong with the plants or does it take longer to flower?. We actually couldn't wait for the natives to flower and so purchased some hybrids they flowered the first year and nothing ever since.
