Ageratum

Ageratum houstonianum

Ageratum is such a little workhorse that nearly every garden should have some. This annual is an easy-to-grow, old-fashioned favorite that produces a steady show of colorful powder-pufflike flowers from late spring through frost. It's also rarely bothered by pests, so you count on it to look good. Plus, it provides some of the truest blues you can find in flowers -- a rare thing.

Plant in spring after all danger of frost has passed. Plant in groups of a dozen or more for best show. Deadhead and fertilize regularly for best blooms.

Salvia
There are few gardens that don't have at least one salvia growing in them. Whether you have sun or shade, a dry garden or lots of rainfall, there's an annual salvia that you'll find indispensable. All attract hummingbirds, especially the red ones, and are great picks for hot, dry sites where you want tons of color all season. Most salvias don't like cool weather, so plant them outdoors after all danger of frost has passed.
French Marigold
Just as you'd expect from something called French, these marigolds are the fancy ones. French marigolds tend to be frilly and some boast a distinctive "crested eye." They grow roughly 8-12 inches high with a chic, neat, little growth habit and elegant dark green foliage.They do best in full sun with moist, well-drained soil and will flower all summer long. They may reseed, coming back year after year, in spots where they're happy.

Annual vinca
You've gotta love annual vinca -- it really delivers. It will tolerate a wide variety of conditions and still keep it up with almost unreal-looking, glossy green flowers and pretty pink, lavender, or red flowers that look like tiny parasols.Whether the summer is dry or wet, hot or cold, vinca plugs along unfazed. It makes a great container plant. Or plant it in a bed or border, grouping at least eight or more together for best effect.Plant established seedlings in spring after all danger of frost has passed. Vinca withstands drought but does best with moderate moisture. Fertilize occasionally. Like impatiens, this plant tends to be "self-cleaning" and needs little deadheading.Shown above: Pretty in Pink vinca
