or aquatic habitats. The symbols also indicate whether plants require winter protection, are used in window boxes, are medicinal or toxic, are used as cut flowers or fruit decoration, or are otherwise useful. There is even a symbol for fragrance. Even

into areas with more severe winter conditions, cultivars with increased winterhardiness and systems to protect blackberry plants from winter injury are needed. Improved trellis design and cane-training techniques along with enhanced winter protection

, and the necessity for increased precision in irrigation and fertilization practices all increase production costs over field-grown material. Other disadvantages of container growing include the need for winter protection, root mortality from lethal

plants were maintained in an isolated nursery area until they were covered with a polyethylene foam blanket (Hummert International, St. Louis, MO) and plastic sheeting for winter protection. On 20 Apr. 2014, sedge plants were uncovered. One-year-old ‘Bob

black plastic provided greater winter protection than a bare-soil production system with straw mulch applied in the spring, and directly led to greater marketable weights and bulb diameters. Two varieties, ‘Idaho Silverskin’ and ‘Persian Star’, were the

, ‘Félix Leclerc’ cultivar can survive in Canadian zone 3A with a small cover of snow or in zone 3B without winter protection. The use of this cultivar may to be marginal in zones 3A to 8B due to tip damage. The cultivar reached its full potential for

climatic zones 3A to 9B during 1999 to 2005 ( McKenney et al., 2001 ; Ouellet and Sherk, 1967 ). ‘Emily Carr’ can survive in Canadian zone 3A with a small cover of snow or in zone 3B without winter protection but is well adapted to zones 5B through 8B

the American origin grape cultivars, and winter protection is required in regions having a cold climate. ‘Sujeong’ vines have relatively high disease resistance to powdery mildew ( Erysiphe cichoracearum DC.) and gray mold ( Botrytis cinerea Per

previously described. Potted seedlings were grown outdoors under natural conditions with supplemental irrigation for anatomical and budding experiments. On 25 Nov. 2007, potted seedlings were covered with a polyethylene foam blanket for winter protection

winter provided satisfactory winter protection for trailing ‘Siskiyou’ blackberry to produce >12 lb/plant in Kearneysville, WV (USDA Plant Hardiness Zone 6b). Trailing ‘Siskiyou’ blackberry produced high-quality fruit in early summer. Information on the
