Chances are, you've got mixed conditions in your garden. One area might be in full sun, while another spot a bit farther away is in full shade. Even beds that have the same exposure on paper may have larger plants that shade out the ground below. This presents a challenge for developing a cohesive look within a landscape. As gardeners, we've been taught that repetition is one of the tenets of good garden design. But how can one repeat groupings of a plant throughout a border that stretches from bright light to dappled shade? The answer is by utilizing plants that are highly adaptable and will thrive in both sun and shade. In today's episode we're singing the praises of these flexible species. They are invaluable assets to the landscape and, as a bonus, will hold their own when the light conditions of a garden inevitably change over time.
