Bambusa oldhamii --Oldham's Giant Green Timber Clumping Bamboo--

ENORMOUS grower up to 55 feet with 4 inch culms and is cold hardy to 20 degrees. Oldhamii makes a spectacular tall windbreak or a focal point specimen. It’s culms are very straight and erect and often used in furniture and construction. Branching behavior depends on environment - Florida plants rarely show branching, but in California are known to branch almost to the ground. The new shoots of Oldhamii are also edible!
Clumping bamboo is an underappreciated gem. It grows fast, looks great, and has endless uses—think strong building materials, eco-friendly fabrics, and more. It’s sustainable and tough, yet people still overlook it. Some fear the spreading kind, but clumping bamboo? It’s a different story—beautiful, manageable, and worth a second look.
To ensure maximum cold hardiness regularly (every couple of months or more) add a rich compost or mulch to the existing corms. This will also create rapid tight growth of the clump of canes. And though bamboos are very drought tolerant, keep in mind the more water, both through the root system as well as spraying the foliage will keep it looking lush, and tropical and helps to maintain a peaceful mind.
