Garden Plant Pots

There are many flowering shrubs that would add beauty to your new garden. Fall is also a good time to plant bare-root shrubs, but container-grown shrubs may be planted any time of the year, except when the ground is frozen.

Hydrangea are a popular shrub, and are available in many bright colors. The Golden Chain Tree, which flowers in the spring, is a unique and beautiful shrub, as is the Japanese Red Quince, that flowers and produces fruit in the fall. The Hardy Crape Myrtle is another colorful shrub that flowers in midsummer.
