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.
