plants that repel unwanted insects

Repels mosquitoes. You’ve no doubt seen citronella candles in stores during the summer and read how citronella will keep mosquitoes away. Citronella is a natural oil found in lemongrass, an ornamental that can grow up to 4 feet tall and 3 feet wide in one season. This grass with wonderful culinary uses is hardy only in South Florida (Zone 10), so almost everyone will have to grow it as an annual. It does well in a pot or in the ground in a sunny, well-drained location. Use its fragrant, narrow leaves in chicken and pork dishes and to flavor soups and salad dressing. Many Asian recipes call for lemongrass.
