National Garden Bureau’s members are pleased to bring many new combination ideas that you can use in your own gardens. These recommended recipes have been tested to balance habit, vigor, and form in one combination. This means one plant won’t completely take over or be taken over, by mid-summer. All plants will co-exist happily and will maintain the look and design from beginning to end. These consumer-ready solutions are available at many garden retailers; just ask for them by name. Or, buy the components by variety name and make your own! (Please note how we specify by variety because one petunia is not like another.)
