what is arugula
You won't believe these 10 facts about people. Arugula (Eruca vesicaria sativa) is a leafy green herb of the mustard family. Known also as rocket, Italian cress, roquette, and rucola, it has elongated dark green leaves that are lobed like the leaves of an oak.In the ground, the plant resembles a loose lettuce with long, slender leaves.s it's now August and the arugula is more bitter now than earlier in the season, I wonder if that has something to do with the reaction and potency of the plant chemistry. I was going to tear out the arugula and compost it, but think I'll just open the fence and leave it for the rabbits. Thanks for the postings.
