How to plant arugula
Purchase common arugula seeds.
There are two main types of arugula seeds that you can buy, common and wild italian. Wild italian arugula has more flavor but it's difficult to cook with because it's stemmy and it bolts quickly, which causes it to taste bitter.
Make sure to get common arugula packets if you want lush leaves that are easy to cook with. Start the seeds during early spring or fall.
