Today’s illustration is a detail of another volunteer from last year’s salad garden: an arugula flower. The simple little bloom is actually smaller across than a dime.
Also known as roquette, arugula has long been used as a slightly bitter green in salads and sandwiches. It grows well in shallow soil and is best grown in cool weather and harvested young. Seeds are available from many sources so you can start some now in the open ground or in a container garden. A Smartpot and Formula 707 potting soil suit it very well.
