Swamp Azalea (Rhododendron viscosum, formerly R. serrulatum) is very different among deciduous azaleas. Most rhododendrons (azaleas) do not care for soppy, poorly drained soils. This U.S. native is an exception, indigenous to swamps, bogs, stream edges and wet lowlands from southern Maine to northeastern Ohio south to Florida and […]

Many leaf spots are tan to dark brown in color and may be circular, angular or irregular in shape. Some of the common […]

Sweet alyssum (Lobularia maritima) is one of the easiest annuals to grow. A member of the mustard family (Brassicaeae), it is native in the Mediterranean region and the Canary and Azores Islands (AHS heat zones 3-8). Modern day cultivars possess exceptional heat, humidity, and drought tolerance in summer months once fully established. Alyssums may be utilized in mixed […]

Chinese fringetree (Chionanthus retusus) When in bloom in mid-spring (May), the fringetrees (Chionanthus spp.) definitely will catch your eye. Chinese fringetree (C. retusus), is one of the finest small to medium sized flowering trees, not to be confused with the U.S. native fringetree (C. virginicus) (USDA hardiness zones 5-9). Both produce spectacular white lacy flowers […]

Posted by Hugh on May 4th, 2015
Many areas in the mid-South and northeast U.S. (USDA hardiness zones 6 and 7a) learned a hard lesson in the harsh cold winter of 2013-14. Over the past decade gardeners had been lulled into zone bending, insisting on planting species from a warmer zone. One of them was pampas grass (Cortaderia selloana). Very few clumps survived here […]
