If you are looking for a shrub that can provide a colorful accent or screen, oleander (Nerium oleander) may be the answer. Oleander plants have thick, bright green, 4- to 10-inch long leaves and bloom in a wide range of colors, including white and salmon.nsects. Oleander insect pests include tiny aphids and scales, which feed on leaves and shoots. A yellow oleander aphid infestation can cause yellow or curled leaves, leaf drop and plant death. False oleander scale insects, which look like white specks on the leaf surfaces, cause yellow leaf spots and leaf drop.
