Climbing Hydrangea – Decumaria Barbara – 3 Gallon Pot

Spacing:  4′ or more against a fence or wall

---

One of the few North American native vines that flowers in shade, Decumaria barbara is a hardy, easy-to-grow climbing hydrangea that produces lots of ethereal flat clusters or unique, honey scented creamy white flowers. Flowers appear in May and June against a dark green background of shiny oval leaves. Unlike some woodland vines the climbing hydrangea maintains full leaf coverage from the ground to the very top of the vine. In fall, the leaves turn a pleasing soft yellow before dropping for the winter. 

Fast growing, this beautiful vine climbs up to 5 feet a year to 30 or more feet in height attaching by rootlets to wood, brick and other surfaces. Great for climbing tree trunks! 

Decumaria won’t bloom unless it’s climbing, but its foliage makes a lovely and lush groundcover all on its own. Though it tolerates dry periods it’s great for moist Southern gardens with seasonal flooding.

Decumaria barbara is a North American native Climbing Hydrangea that provides wonderful texture and color as a vertical accent in home foundation plantings, on trellises, arbors, pergolas, mailboxes, and up tree trunks.

The vines will trail over the pot and climb the structure creating a unique and interesting feature.
