Once a rare delicacy, Arugula is now part of the American dinner table. But for what it costs at the fresh market, growing your own is the only sane option! And it's a good thing it's so easy to grow!This plant reaches about 2 1/2 feet tall and 1 foot wide, with leaves best cut at 2 to 3 inches long. Cut just what you need for the next meal; each leaf that is severed stimulates production of more foliage, so a single plant can keep producing over a long season. And the flavor is so delectable when the leaves are young and tender -- peppery and mustardy, with a palate-cleansing zing! Great in pesto, too -- just don't let the leaves get too big, because they will lose their tender texture with maturity.
