I don't think the roots, even without soil, would make it through customs. MAYBE with enough prep before with phyto cert and import paperwork...would be interesting to see what hoops one would have to clear to make it happen. I'm pretty sure it's harder to get plants and animals into New Zealand (I KNOW it was for Australia) than it is to get them back to the states but still...
Seeing the pics on their website makes me curious about New Zealand and Australia propagators and the unique plants they've produced. Would love to see some documentation and pictures of the most distinctive.
I know here in the states that several propagators have some amazing plants in the works. The tour we did of Solaris Farms in June was truly eye opening! I took LOADS of pics, still have tons of work to do outside so just took a quick look and am posting a couple of TP seedlings that caught my eye. The last pic isn't a seedling but is named variety Angel Choir. I remember how excited I was when I saw the plant tag--I'd ordered it from Solaris for this fall but hadn't seen it live--was oh so happy that it was going to be added to my garden!
