- A good choice for gardens in warmer areas with long growing seasons as this spinach substitute with a similar taste is slow to bolt and performs well through the summer.
Non-GMO New Zealand Spinach is an excellent option for warmer gardens because you get a longer growing season. Not spinach, but a more heat-tolerant substitute for spinach. Similar taste to spinach and they can be used in cooking the same way. As the spring spinach is bolting, New Zealand spinach hits its stride and continues through the summer and into the fall. The plants are larger than spinach.
