The Q&A Archives: Tall Blue And Purple Flowers

Question: I have seen the most beautiful blue and purple flowers while vacationing on the west coast of Michigan. Would you be able to help me identify them. I think they were perennials but can not be sure. The were about 3 feet tall, and came in different shades of blue and purple, from light to dark. The leaves were medium to dark green. The flower itself was about 6 inches in diameter and was shaped almost like a ball. I have seen these in white flowers only but i dont even know the name of them, the white ones i have seen are more like a bush, so i dont even know if it is the same plant. I live in southeastern Michigan and would love to have these in my yard, would they grow here?

Answer: I think you may have seen the big leafed type of hydrangea, Hydrangea macrophylla. These plants will produce blue flowers in acid soil and pink flowers in neutral to alkaline soil. They might grow for you in a very sheltered and protected location out of winter wind. In too cold a location they may survive but will not bloom if they are killed back by winter cold. They need a rich, evenly moist yet well drained soil (meaning not soggy) and full to partial sun.
