NZ Native Flax (Harakeke.) 

I have no idea what would have made these tear shaped holes in this leaf. Flax is a tough, fiberous plant and not easy to put a hole through. It’s so tough that in early settler days it used to be farmed in certain swampy parts of NZ where it was than milled to be used for rope making. The photo below shows the ‘sheath’ that protects the flower as it forms. It’s a purple/grey coulour which turns brown when it dries off and reveals the hidden treasure it’s been protecting inside.
