Cosmos? New Guinea Impatiens - or 'ordinary' Impatiens single or double? Swiss chard with coloured stems? Coleus? Radiccio? Purple Sedum or broccoli? Bedding dahlias - if you can catch the red or pink streak of the tropicanna? Pink sage? Lantana? Dark basil?

Mine are interplanted with Eucomis "Sparkling Burgundy", which echo the canna's dark foliage (propagated via leaf cuttings) and Sinningia selloviae, with red spikes of bloom all summer. Both of these are reasonably hardy here and like the same conditions as the cannas - lots of water and warmth in summer, drier with a deep mulch in the winter. There's kind of a cool contrast among the colors and shapes of the blooms as well.

I have some daylillys,salvia& red castor beans,amaryllis,glads& yes basil /ruby something it has purple leafs& does better than purple ruffles.If i don't let it flower it keeps the dark coloring& gets bushier then in oct I'll let it flower....it gets the greenish cast just like purple ruffles then.The 1st year I grew them.I planted blackie sweet potato vine& had yellow mums near them also.but was mad the cannas didn't bloom.They get full blasted sun now.I might move some mums back by them.A good vine would be black eyed susan vine.
