Why grow spinach?
Would you believe that English spinach doesn’t grow that well here? It’s not cold enough! Not to worry, there are plenty of plants that could be substituted for spinach that do grow themselves in this area. Winter greens that aren’t spinach – longevity spinach, okinawa spinach (both subtropical perennials), dandelion, flatweed/cat’s ear, nasturtium, sweet potato leaves, chickweed, buckwheat leaves, broadbean leaves (young), snowpea leaves, comfrey (young leaves, cooked only), all the asian greens, tatsoi, rocket & mizuna, collards, brassica leaves (cabbage, broccoli, cauliflower), kale, rainbow chard & silverbeet.
These might not be as well known or known as greens, which is perhaps why people persist against the odds in trying to grow spinach. However any of these will be easier to grow here and used in similar ways depending on your tastebuds.
