An Herb Garden
What to Plant: A gallon-size rosemary plant and a quart-size sage plant form the foundation of this 4 1/2-by-3-foot herb garden. Oregano, thyme, parsley, and basil add visual contrast.
Other Options: Anything goes, depending on your palate. Consider a themed garden, such as one planted with lemon thyme, lemon basil, lemongrass, and lemon balm.
How to Maintain: Herbs are relatively self-sufficient, so water about once a week more often during dry spells and less during rainy periods. Make sure to direct the water gently toward the base of the plants, which prevents runoff and allows the moisture to percolate down to the roots.
