If you love morning glories, try this low-growing cousin, which has even more gorgeous sky blue flowers. Like the morning glory that grows upward, this more earthbound beauty produces striking blue flowers all season long. And like its cousin, the flowers tend to close in the afternoon hours. In Zones 8-11, in the warmest part of the country, this tropical is a perennial; farther north, it's grown as an annual. Its spreading habit is perfect for spilling over baskets, window boxes, and other containers.
Plant established plants outdoors after all danger of frost has passed. Evolvulus likes rich, well-drained soil and needs just average water. It's somewhat drought-tolerant, so don't overwater.

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.
The adorable cup-shape flowers of nierembergia and its neat growth habit make it a useful annual flower for everything from containers to edging. Plant it in rows along the front of beds or borders for a crisp look (especially with the white types). Or use it in containers -- it's a great medium-height plant to visually tie together taller plants and cascading plants. Though it's usually grown as an annual, nierembergia is perennial in Zones 7-10.
If you love blue flowers, tweedia is for you. Tweedia produces beautiful turquoise blooms all season on grayish, felted foliage. The fragrant five-petal flowers make great cut flowers, complimenting any bouquet. A short vine growing 2 to 3 fall, tweedia will twine around short trellises or other supports. (Try a shrubby branch cutting, inserted into the soil for a naturalistic support.)
