Best flowering tree / shrub for a small planter box?

Question

I have a small planter box that runs the length of my back yard. It is only about a foot to a foot and a half wide. I am trying to figure out what would be best to plant in there. I'd like to get some kind of a flowering bush or small tree to line the planter. It doesnt get alot of sun, mostly late afternoon and early evening sun. I just want to put some color in there but need something with a little bit of hieght to it...

Answer 1

There are a number of dwarf forms that would do well in containers. Phormiums from New Zealand like 'Platt's Black,' with narrow leaves and near-black spiky blades can add the height with a strong punctuation.
If you like hardy fushias, they can offer vivid color in a graceful flowing form.
Dwarf rhododendrons, often alpine species, are solid year round elements that offer color in spring.
Include a layer of small bulbs to start the growing seson then fill with annuals as needed.
A small trellis could support one of the smaller scrambling clematis vines. There are even miniature climbing roses that would do well in containers as well as the entire patio rose class. http://www.sequoianursery.biz/

I'm not sure what part of the country you live in, but Abutillon (flowering maple) are great. They come all colors (white, burgandy, orange, red, yellow, pink). They don't require a lot of sun or a lot of care and they can flower ALL YEAR LONG. The flowers are bell shaped lanterns. The shrubs will adapt to the size of their habitiat. I have some that are only 3-4 ft tall and some that are 10ft tall and 4 ft wide.
