Last year, I attempted to grow Tragopogon porrifolius (salsify) 'Mammoth Sandwich Island' (I think). It didn't go well. I tried planing salsify and parsnips in the same bed and both failed. It may have been uneven moisture levels at the start.
So, I want to try again. I would like to try regular and Scorzonera hispanica (black or Spanish salsify) together. I'd also like to try parsnips again.
Anyway, are there any gastrointestinal issues with either salsify? I love Jerusalem artichokes but just can't bring myself to eat them any more as they tend to give me extreme GI upset to the point of pain. I also don't grow them as I need the space for other vegetables that may more easily fit into dietary needs.
Any tips to growing salsify? Comparison between the two plants mentioned above?
