Often overlooked as container plants, shrubs offer seasonal interest, structure and fun in planters of all sizes. There are just a few simple rules to follow. To start with, grow them in weatherproof fiberglass, concrete or plastic containers with drainage holes. It’s also important to select container shrubs one or two zones hardier than usual to help them overwinter in colder climates. Finally, don’t be afraid to grow them in the company of annuals, perennials or even other shrubs. Ready to try it yourself? These 10 shrubs will not only perk up your small space garden, they’ll also help you attract birds and butterflies!
