This season, you’ll feel extra good about your purchase of the new Invincibelle Spirit II Hydrangea for your garden or to give as a gift. That’s because $1 of every plant sold is donated to the Breast Cancer Research Foundation. More than $730,000 has been raised from the sale of its predecessor.
Invincibelle Spirit II is a notable improvement over the original Invincibelle Spirit. It is a much stronger grower, with sturdier stems, darker green foliage and brighter blooms. Rich pink flowers are produced on new growth from mid-summer until frost, maturing to an attractive shade of green. The dried blooms are lovely in long lasting bouquets. This selection of our native Hydrangea arborescens grows and blooms best in full sun, but will also grow in part shade at the expense of fewer flowers.
