Prefers moist, well-drained soil but will tolerate some drought once established. Will often rebloom. The first pink-flowered 'Annabelle' hydrangea. $1.00 from each plant sale is donated to the Breast Cancer Research Foundation.

This is a smaller hydrangea, reaching about 3-4 feet tall and wide at maturity. This one benefits from some deliberate pinching back of the growth tips of each branch the first few years, as it tends to grow very leggy and flop onto the ground otherwise. Some careful shaping when immature will help develop strong "bones" to shape the plant. Mine blooms throughout the summer, aging from pale pink to a dark rose color. Mine is in nearly full shade, and is thriving.

Hydrangea arborescent 'NCHA1' was developed by Thomas G. Ranney as a collaborative project between NC State University and Spring Meadow Nursery at the Mountain Crop Improvement Lab™. It is marketed as 'Invincibelle® Spirit' and is one of the first pink flowering smooth hydrangeas (PP20765, ~2010). It is commonly referred to as a pink version of 'Annabelle.' Cultivars Invincibelle® Spirit II and Invincibelle® Ruby followed in 2017.
