I have not tried to grow Limas in many years and the one year I did I don't remember any great success. I just buy my shelling beans and grow the types you eat fresh. But I did try cowpeas last year, which are really a type of bean and not a pea. I found I didn't have enough room for a decent crop and my few plants didn't do much. So I will not be trying those again.
It was my opinion that the Black Seeded Blue Lake I tried last year had a stronger bean flavor than the traditional Blue Lakes which have a white seed.
The burgundy purple beans tasted good but if you cooked them in a mixed bean dish you would never know they came from peuple beans. They do turn green. Last year my favorites were the yellow varieties. To me these were the most tender and had a really nice taste.

Scroll down the page. To show you about taste differences in what people think, year before last I had grown the Spanish Musica because I had read people raving about it. I thought it was so bad that I only tried eating them once and pulled out the vines immediately after as I was not about to eat them again.
