Perennials, including ornamental grasses, roses, and ferns, are often grown in quart, one-gallon, or two-gallon containers and set out for display and sale when they are in full bloom. Although spring and fall are the best planting times, container-grown plants can be planted safely even during the height of summer if they are kept watered. Gallon containers can be expensive, and they create just a single clump in the garden. Even though they are smaller, several quart-sized plants for about the price of a single large one make a better choice because you will be able to arrange them into an attractive drift. Always remember that once in the ground, plants will spread and grow much taller.
Shop wisely. Beware of poorly cared for plants - improperly trained or busy personnel in discount centers may neglect plants, allowing them to wilt repeatedly, thus stressing the plants. Look for plants with healthy, dark-green foliage, indicating that the plant has been properly watered and fed. A trail of roots hanging from the container warns of a root-bound plant that may not transplant well.
