Arugula comes in 2 different species, common arugula and wild arugula aka perrennial wall rocket. They can not interbreed as far as i know. The former (2nd pic) is mild while the latter (1st pic) is more bold and peppery. common arugula has white to creamy yellow flowers while wild arugula has bright yellow flowers. Both attract loads of pollinators. Which is your fav??? #homesteading #seedsaving #arugula #garden #gardening
