NZ growing notes
Useful coastal and dry-edge green. Young leaves are preferred; older leaves can be high in oxalates — cook and do not overconsume.
In the food forest
NZ spinach covers sunny dry and coastal edges as an edible groundcover beside harakeke and feijoa. Keep tip-pruned for tender leaves.
Establishment
Sow or plant in spring into free-draining ground. Water to establish. Harvest young tips often. Allow some plants to seed if you want volunteers.
NZ honesty
Honest on coastal and mild temperate sites. Hard inland frost may kill tops — expect seasonal behaviour.
