Bill I think you live somewhere warm because you grow Malabar spinach. Not very nice tasting but very pretty.
English spinach likes cool weather. Silverbeet does not mind the heat, but there are different varieties in all sorts of colours.
The red stalled one does look good in the bed but awful once cookes. And there is a very thick stalked variety too I don't find it very yummy.
I prefer a thin stalked green variety call lucullus or so. You can cut it an it comes back several times.
There is NZ spinach which is
perennial, supereasy to grow but a bit more reluctant to germinate. However the leaves are as small as is lambs quarter.
It is a nice groundcover though.
