Summertime is basil-time in the Old Pueblo. As the nights turn to their sultry summer phase, the sun provides light for hours on end, and the soil temperatures become toasty warm – in other words, we enter our tropical phase of the year – and basil is truly delighted. Originally native to India, basil is genetically a tropical plant, even though it is now grown around the globe wherever (and whenever) it is warm enough.

Basil is a real taste treat. It can be used in Italian cooking (like the pesto recipe below), fresh, in green salads, and it even has a reputation as a medicinal herb.

Basil does grow well in the Tucson area, but it isn’t the easiest herb to grow. It has some very specific preferences if it is to thrive. I will put growing tips up on my Gardening With Soule blog on June 4th. Why wait? Because the 4th of each month is national “You Can Grow That” Day.

I was in Philadelphia and spotted a bunch of basil growing in a raised bed. Ideally, you want to pinch the blooms off to encourage more leafy growth.

The National Institute of Health reports that Americans consume too much salt. Cooking with flavorful herbs like basil could help you reduce your salt use and stay heart healthy.  Here’s an easy to make pesto to get you started.

Basil Pesto

4 oz. fresh basil leaves (a generous double handful)
1/4 cup pine nuts
2 cloves garlic, peeled (double amount of onion may be substituted if garlic is an issue)
8 tablespoons olive oil
1/4 cup grated Romano cheese
1/4 cup grated Parmesan cheese

1. Rinse basil and pat dry.
2. Toast pine nuts in an ungreased skillet over medium heat until golden. Cool.
3. Place cooled pine nuts, basil, garlic and olive oil in a food processor or blender and puree until creamy.
4. Stir in the cheeses and serve over pasta or rice. Also excellent with quinnoa or toasted tofu. Vegans can omit the cheese or use shredded soy cheese.
