If you need help with plant disease identification and control, check out Plant Disease Facts from Pennsylvania State University, a very useful site for home gardeners. It provides a wealth of information on diseases of garden and landscape plants, referenced by the disease as well as the plant species.

When summer heat arrives, most of our flower palate is concentrated in hues of yellow, orange, and red. Blue flowers are the exception, but one exceptional blue- blooming perennial is bluebeard (Caryopteris X clandonensis). Several varieties are available, offering varying shades of blooms and foliage. Bluebeard grows best in full sun and good drainage. Once established, it's fairly drought tolerant and blooms best with little to no added fertilizer. As an added bonus, the blooms attract swallowtail, monarch, and viceroy butterflies.
