You'll be stung with a hefty fine if you get caught bringing seeds into New Zealand! I even had to remove flowers I had dried in my journal (but was spared the fine)
True - I think prison is also on the cards for more serious biosecurity breaches.
Whilst on one hand I love the idea, who knows what the potential consequences are? In NZ we suffer a lot from our ancestors decisions on imports, well intentioned as they were at the time.
Here in Germany, the local grass verges are rapidly becoming Rocket (peppery flavoured salad plant) in the summer. (And yet you can still buy the seed/ plants readily).
Of course, people still buy it in the supermarket, either a/ from ignorance; b/ laziness or c/ because the grass verge’s are also the local dog toilet’s!!
Either way, I’m pretty sure that’s a classic example of an unintended consequence. Not knocking you, appreciate why you would want to do it, just suggesting you make sure it doesn’t spread.
