Arundo donax var. versicolor

Variegated Giant Reed

USDA Zone: 6-9

Plant number: 8.040.100

Very popular for use in large perennial beds, often seen grown as a large specimen or focal point in parks and botanical gardens. Plants form a tall upright clump of corn-like leaves, strongly striped with green and white or creamy-yellow. Spikes of pinkish flowers may appear in the autumn. Roots can become large and woody, so division of old clumps in spring can become quite a task. Where not hardy this may be grown in a container, cut back in late fall and wintered indoors.

Arundo donax, giant cane, is a tall perennial cane growing in damp soils, either fresh or moderately saline. It is one of the several species of the so-called reed. Other common names include Carrizo, Arundo, Spanish cane, Colorado river reed, wild cane, and giant reed.

Arundo donax is native to the Mediterranean Basin and middle east Asia, and probably also parts of Africa and southern Arabian Peninsula. It has been widely planted and naturalised in the mild temperate, subtropical and tropical regions of both hemispheres (Herrera & Dudley 2003), especially in the Mediterranean, California, the western Pacific and the Caribbean. It forms dense stands on disturbed sites, sand dunes, in wetlands and riparian habitats.

Arundo donax generally grows to 6 metres (20 ft), in ideal conditions it can exceed 10 metres (33 ft), with hollow stems 2 to 3 centimetres (0.79 to 1.18 in) diameter. The leaves are alternate, 30 to 60 centimetres (12 to 24 in) long and 2 to 6 centimetres (0.79 to 2.36 in) wide with a tapered tip, grey-green, and have a hairy tuft at the base. Overall, it resembles an outsize common reed (Phragmites australis) or a bamboo (subfamily Bambusoideae).

Arundo donax flowers in late summer, bearing upright, feathery plumes 40 to 60 centimetres (16 to 24 in) long, that are usually seedless or with seeds that are rarely fertile. Instead, it mostly reproduces vegetatively, by underground rhizomes. The rhizomes are tough and fibrous and form knotty, spreading mats that penetrate deep into the soil up to 1 metre (3.3 ft) deep (Alden et al., 1998; Mackenzie, 2004). Stem and rhizome pieces less than 5 centimetres (2.0 in) long and containing a single node readily sprouted under a variety of conditions (Boose and Holt, 1999). This vegetative growth appears to be well adapted to floods, which may break up individual A. donax clumps, spreading the pieces, which may sprout and colonise further downstream (Mackenzie 2004).
