taxonomic confusion w/less common brassicas
Territorial seed lists red Russian and dwarf Siberian kales as B. oleracea, but Southern Exposure lists them both as B. napus. Which are they (and are the two even the same species)?
And what about Mizuna? Southern Exposure lists it as B. rapa. Will it really cross with turnips but not with other mustards?
What about the kind of kale sold also as rape? Is it B. oleracea or B. napus?
And what kind of mustard do I want to grow to make a homemade version of regular, American-style mustard? I read somewhere on the internet that it was B. hirta, but Seed to Seed says it's not B. hirta but it's B. nigra. Why is it called black mustard? Will black mustard make a light colored mustard? In any case, can anyone recommend a seed source? Any chance I can buy whole culinary mustard and use it for seed and it germinate?
Is there a way I can personally identify species differences between brassicas? In other words, are there visible difference in the flowers or seed heads, etc. I can use to confirm what species a particular brassica is?
