One of the longest bloomers in the garden, hardy geranium bears little flowers for months at a time. It produces jewel-tone, saucer-shape flowers and mounds of handsome, lobed foliage. It needs full sun, but otherwise it is a tough and reliable plant, thriving in a wide assortment of soils. Many of the best are hybrids. Perennial geraniums may form large colonies.

Astilbe brings a graceful, feathering note to moist, shady landscapes. In cooler climates in the northern third or so of the country, it can tolerate full sun provided it has a constant supply of moisture. In drier sites, however, the leaves will scorch in full sun.Feathery plumes of white, pink, lavender, or red flowers rise above the finely divided foliage from early to late summer depending on the variety. It will spread slowly over time where well-situated. Most commercially available types are complex hybrids.
Daylilies are so easy to grow you'll often find them growing in ditches and fields, escapees from gardens. And yet they look so delicate, producing glorious trumpet-shape blooms in myriad colors. In fact, there are some 50,000 named hybrid cultivars in a range of flower sizes (the minis are very popular), forms, and plant heights. Some are fragrant.The flowers are borne on leafless stems. Although each bloom lasts but a single day, superior cultivars carry numerous buds on each scape so bloom time is long, especially if you deadhead daily. The strappy foliage may be evergreen or deciduous.Shown above: 'Little Grapette' daylily
Named for the Greek goddess of the rainbow, iris indeed comes in a rainbow of colors and in many heights. All have the classic, impossibly intricate flowers. The flowers are constructed with three upright "standard" petals and three drooping "fall" petals, which are often different colors. The falls may be "bearded" or not. Some cultivars bloom a second time in late summer. Some species prefer alkaline soil while others prefer acidic soil.Shown above: Immortality iris
Easy and undemanding, veronicas catch the eye in sunny gardens over many months. Some have mats with loose clusters of saucer-shaped flowers, while others group their star or tubular flowers into erect tight spikes. A few veronicas bring elusive blue to the garden, but more often the flowers are purplish or violet blue, rosy pink, or white. Provide full sun and average well-drained soil. Regular deadheading extends bloom time.
