    Uses Notes: 

    Excellent for mixed borders and cutting gardens.

    Maintenance Notes: 

    Prune to shape after flowering. Flowers set on previous season's growth, so do not prune severely. Protect overwinter in harsh climates. Grows best in moist, well drained soil. Supplemental water may be needed in very hot weather. Apply a controlled release fertilizer in spring. Add aluminum sulfate to the soil to encourage blue flower color.

    Distinctive variegated blooms.

    Large intense blooms with dark, pinkish-red flowers accented by a thin white line along the margin. This small to medium sized plant has strong stems and glossy foliage, and the flowers are good for cutting. Flower color can be pushed to blue with the addition of aluminum sulfate to the soil.

    • This is the 3rd summer for the plant which I planted 2 years ago in the spring. Only a few flowers the first 2 years. Late frost last year may have killed the buds. This year it looks spectacular. 24" in height width and covered in flowers that look exactly like the pictures shown. I have 3 shrubs planted on the north side of our attached garage along the walkway to our front door. The best looking hydrangea in my garden as I have 2 other Endless Summer hydrangeas

      Above Average Superior performance, among my favorites, would recommend to others.
    • I have had this for at least 5 years. Not once has it bloomed. The top part dies off in the cold. I have had it in the ground as well as a pot. No luck either way. Top kill occurred even when the plant was placed in the garage! Overrated humbug.

    • Sorry to report that I paid full price two years ago for this hydrangea, and it has never thrived. I should have known better because it did not look robust at purchase. I have about 80 hydrangeas, and this is the first I have not had success with. Now it is in its third spot for a third try before I discard it.
