The Trader Joes Premium White & Blue Hydrangea are grown in the mountains of Medellin Colombia. The shade of blue varies depending on the acidity of the soil and the time of year. The color can range from light to a dark blue. The white can appear more creamy yellow when it’s cut tight. As the flower drinks water and opens the heads will grow in size and the Hydrangea will turn a more pure white. Hydrangeas make a beautiful base in an arrangements or can elegantly stand alone in a vase.
