Avoid too many brightly colored hostas
Gold works best when clustered into drifts that draw the eye from plant to plant. When gold hostas are sprinkled throughout a border, they make the composition look spotty.
One common mistake gardeners make when designing with hostas is to try to create interest with a heavy use of showy gold or variegated hostas. Because these plants pop out at you, too many of them make a garden seem chaotic rather than harmonious. To balance your design, use mainly green, blue, or subtly variegated hostas. It’s easy to balance these hostas because they are unlikely to clash with other plants around them or clamor for attention. You can use green, blue, and lightly variegated hostas almost anywhere to support other plants, add structure, and make the garden lush. These hostas have a quiet presence. The more of them you have, the more restful your garden will be.
Another reason strongly variegated or yellow hostas can be hard to design with is because they catch and hold the eye. Most hostas with white variegation make great focal points, but not all gold hostas do. The brightness of their leaves depends greatly on how much sun they get. In full shade, gold hostas tend to turn chartreuse. They are at their best when grown in morning sun because it provides enough light for their gold color to develop without scorching their leaves.
