The JC Raulston Arboretum Lath House is home to a wealth of interesting plants many of which are too new to have actual cultivar names yet. This hydrangea hails we assume from one of our favorite nurseries (Chicory Nursery) in Japan where rows and rows of interesting plants line shelves. We received it from another source and think this plant is hard to beat. It is a small Hydrangea serrata with leaves heavily speckled with white. Dainty lacecap flowers which vary from pink to blue depending on soil alkalinity and availability of aluminum in the soil (blue if aluminum is available and the soil is acidic enough for it to be in solution). Even non-variegated plant lovers can appreciate the subtlety of this plant. Grow in some shade in a moist, well-drained soil.
