Nursery contributed plant descriptions

You just can’t cook Thai food properly without this essential ingredient! This Basil has the anise undertones necessary to evoke authentic flavor in dishes and growing your own is really the best way to have it on hand in the fresh state, when all of the essential oils are most potent! The quintessence of Summer, I can't think of anyone who could object to fresh, home grown Basil. Rich Soil, regular water and full Sun are what basil requires. To 1’ or more in height and width, pinch tips back for bushier plants, with more fresh tips to harvest from. After you’re done with your culinary harvest, let the plants flower – they have some of the best flowers for bees!
Outstanding fragrance and flavor with larger leaves and thicker stems producing higher yields of greens. Can be harvested for 4 months..sunny, evenly moist, well drained soil...
