Gem colored flowers that age to magical hues.

Hydrangea macrophylla Garnet™

Flowers emerge bright, reddish-pink or blue, depending on the soil acidity, fade to a deeper pink with green highlights, and then finally age to bright lime green with pink edges.

We know you will love our hydrangeas with their long lasting, strong flowers, their variety of colors, and handsome foliage. As the flowers age, they change from one exciting color to the next.  You will enjoy many colors at one time as each flower lasts for months.  Each stem is a bouquet; even a young plant will give you months of blooming enjoyment. Garnet™ is covered in saturated, gem-colored flowers on a compact and sturdy garden plant. Blooms are supported by thick, upright stems emerge bright, reddish-pink or blue, depending on the soil acidity, fade to a deeper pink with green highlights, and then finally age to bright lime green with pink edges. As the flowers age and change colors, they last for weeks on the plants, in the garden, and as a cut flower in a vase on your breakfast table.

Please note: We don't sell plants. Asking your local retailer or googling the plant name is the easiest way to find someone selling our plants.
