Little Lamb Panicle Hydrangea. 'Little Lamb' is larger than 'Dharuma' but not as large as 'Limelight'. Flowers early in the season. The "Peegee" type Hydrangea do best in full sun. So this is a welcome trait for those who don't have enough shade to grow the "macrophylla" types. Another note is that they flower on current seasons wood, so one can prune them back heavily each spring to induce more succulent growth which results in larger flower heads.
