When watching this video, you will realize why Lamb's Ear, or stachys byzantin, may be a perfect choice of plant to set in front of your other plants. With a sea green color and low profile, it will set the rest of the garden off beautifully. Place it along borders of the garden or even along your driveway. Lamb's Ear is a hardy, drought resistant plant that is easy to care for and will do well in sunny areas. It does shoot up and grow a large flower later in the season. This would be your option. If you wish to cut the tops, it won't damage the plants to do so.
