You should grow white mustard if your planning to make the condiment. Other varieties are grown more for leaf.

It says 35-60 cm apart. I would suggest plants 40-50 cm between them and rows 40-50cm apart.

Please advise where in Adelaide SA I can buy leaf mustard (aka mustard greens) seeds. Every time I think I’ve found somewhere the seeds turnout to be the variety that you cook with not the ones I want to plant in my garden. Thank you to anyone that can help me.

This Autumn and Winter I scattered mustard seeds around the place - a biodynamic book said to do that. When I'm weeding I see a nice mustard green I just eat it on the spot. Leave some patches to grow bigger and eat them chopped up in your dal/lentils - stem & all. Keep sowing them all the year.
