Annual Flowers
This is the starting point for describing how to grow annual flowers. And while all these plants listed here can all be grown from seed, there are some varieties that are only from cuttings. For example, in the impatiens page I mention New Guinea Impatiens and while there is a species, most of the plants you’ll find are only grown from cuttings.
Annual Plant Trials 2008
These are some of the best plants I saw at the Landscape Ontario plant trials in August of 2008. Note that all of these plants would be excellent in container baskets of some kind.
