Thanks for the compliment and the questions! Most plants, depending on their size and growth will out grow a container, it's just a matter of time. The fun is that it pushes you to try something new. This is a very summer loving container. Fall you'll see the Burning Bush turn to a brilliant red then drop its leaves. The Brunnera will fade away for the season as will the Bleeding Heart. The Long Leaf Mahonia will stick around and if you add in winter annuals you'll have something till the new flush of growth. Add spring bulbs and Hellebore for January/February Blooms. Have fun!
