Our Experience

Experience at Great Hill

We feature spiraea underneath the Great Hill sign, welcoming guests to the estate. As the sign area is a walk from any other maintained location on the estate, spiraea is the perfect shrub to feature there. It is relatively a no maintenance shrub, being drought and heat tolerant and having no disease or insect issues. Our spiraea flowers heavily each season late in the spring and then sporadically as the season progresses. It’s a wonderful shrub if you’re looking for a low maintenance option, with many cultivars to choose from.
