Decorate your porches and patios with this 1.5 Gal. hydrangea blue flower in a finished white pot from METROLINA GREENHOUSES. Hydrangeas are shrubs with large blooms that are easy to care for. You can even change the colors of the blooms. Soil with an alkaline level of 6 or more will produce pink blooms, while levels below 5.5 will produce blue blooms. You can change the color of your blooms with a hydrangea fertilizer. Place your hydrangeas in part sun, preferably morning sun, and water when dry. At the end of the season, remove your hydrangeas from the decorative pot and plant in-ground to enjoy year after year. Plants ship pre-bloom and slightly smaller than images shown.
