Landscape trials were conducted to evaluate 235 cultivars within 66 species in central Mississippi. All entries were grown from seed or vegetatively propagated material. Raised landscape beds were prepared using accepted regional methods. Planting into beds began on 4 April and was completed on 20 April. Plants were given an overall rating based on insect resistance, disease resistance, vigor, flowering, and foliage color. Each cultivar was rated bimonthly until early August when pruning or termination was necessary, depending on each cultivar, at which time rating frequency became once a month through the first freeze. The rating range was 0 to 5, where 5 is optimum and 0 is death. Height (cm) was measured for each cultivar at the same intervals as performance ratings. Heights were recorded to show the average height of each cultivar. No herbicides were applied; handweeding controlled weeds. No insecticides were applied to plants with the exception of the hibiscus where there was severe pressure from sawfly larva. In 2005 central Mississippi experienced a very hot and dry summer. Strong winds and heavy rains in late August and early September associated with Hurricanes Katrina and Rita took their toll on the trial, especially many of the taller cultivars. The top performing cultivars for 2005 were `Intensia Lilac Rose' phlox (Phlox ×), Proven Winners; `Intensia Neon Pink' phlox (Phlox ×), Proven Winners; `Elliottii Wind Dancer' grass (Eragrostis curvula), Pan American Seed; `Intensia Lavender Glow' phlox (Phlox ×), Proven Winners; `Dolce Licorice' heuchera (Heuchera ×), Proven Winners; `Diamond Frost' euphorbia (Euphorbia ×), Proven Winners; `Gold Flake' mecardonia (Mecardonia ×), Proven Winners; `Titan Polka Dot' annual vinca (Catharanthus roseus), Ball Seed; `Sun Fan' scaevola (Scaevola aemula), Proven Winners; `Golden Delicious' salvia (Salvia elegans), Proven Winners.
