Large pots, urns and planter boxes filled with ridiculously colorful blooming annuals are certainly nothing new. However, more small perennials and even a few small shrubs and trees are being planted along with the annuals, and allowed to stay indefinitely as fewer annuals get replaced around them as the seasons change.
These plants only need to be tolerant of confinement, regular watering and the comings and goings of the annuals around them. Upright plants should go in back, behind the lower annuals. Cascading and ground cover type plants should go in front.
Small forms of New Zealand flax and trunkless dracaena palms (Cordyline spp.) add texture, form and motion to large planters, but may eventually get too big if not properly pruned. Larger shoots can be pruned out to allow smaller shoots to take over. Alternatively, overgrown plants can be removed and put out in the landscape when they get too big.
Hollywood and Rocky Mountain junipers have striking form if pruned to show it off, and are easier to contain with selective pruning than reputed. Even without the interesting branch structure of junipers, arborvitaes are appreciated for their similar finely textured foliage and their rich green or yellow color. ‘Blue Rug’ juniper, a grayish ground cover juniper, cascades nicely from large planters.
Large succulents that tolerate water, such as good old fashioned jade plant and various aeoniums, offer bold texture and form in the background. They are easy to prune as they grow, and do not have aggressive roots. Low clumping aloes do the same in front.
Euonymus fortunei, English ivy, various iceplants and other ground cover plants do well cascading over the edges of large planters.
There really is not much limit to the variety of perennials and small shrubs and even trees that play well with others in planters of blooming annuals, and do not mind the confinement and regular watering. Annuals are still the best for flashy floral colors. Yet, the other plants excel in form, texture, foliar color and motion in the breeze.

Annuals are great in pots.

Yes, and even if they are not the primary occupants of the pots, they provide the most color, and occupy space that weeds might otherwise want to inhabit.
