    In North Island, Tim Vallings at Forest Floor Nursery Maungatapere has been growing various Gahnia for years … 09 4347216 and office@forestfloor.co.nz or you can successfully transplant small seedlings … we transplanted seedlings by hand using spades in ‘in tact’ sods of clay about 20 by 20 by 20 cm … directly from cutover pine forest in north auckland to roadsides – or intermediate planting into plastic bags … both reasonable survival. Also transplanted mature Gahnia with diggers using c. 1 by 1 by 0.5m deep sods … they usually die back for 12-24 months then resprout… but that’s in a pretty wet environment of West Coast…

    Tim will tell you how to propagate by seed (lots of patience). We found scarification helpful
    Let me know if photos of transplants would help.

    Chionochloa rubra and C. australis are much easier to transplant if soils are suitable and moisture stress managed …they also divide. Success on Gondola Project in Christchurch, mining in North Otago and West Coast, ski field roads and hydro developments…
    Suppliers include Southern Woods and Wairere Nursery (C flavicans is easiest) but I think also Kauri Park
