Pleioblastus viridistriatus ( synonym : Arundinaria viridistriata ) is a low, woody bamboo - type that thrives in temperate climates. The country of origin is Japan, but it is also used as an ornamental plant in Central Europe.

description

Pleioblastus viridistriatus is perennial and forms leptomorphic rhizomes . The woody stalks grow upright, are 20 to 60 centimeters long and 1 to 2 millimeters in diameter. The internodes are round, hollow and hairy under the knot just like the stalk knot itself. No or only a few lateral branches are formed. The stem leaf sheaths are finely downy with hairs bent back. The blade blades are lanceolate, about 0.5 centimeters long and stand erect. The leaf sheaths are also finely hairy. The ligule is membranous and may be ciliate. The leaf blade is connected to the leaf sheath with a short, stem-like base. (Sweet grasses do not form petioles). The blade is lanceolate, 15 to 20 centimeters long and 15 to 25 millimeters wide, medium green to yellowish green and striped. Both spider sides are dense, hairy downy. The end of the spread is pointed. The species loses its leaves in winter.

The inflorescences consist of a few spikelets , one to three spikelets being fertile and stalked. The fertile spikelets have six to 8 florets with one not fully developed florets on top. The spikelets are linearly shaped, laterally flattened and 40 to 50 millimeters long. A permanent glume is formed. It is shorter than the spikelet, lanceolate, 10 to 23 millimeters long, membranous, not keeled, seven times veined and pointed. There may be another one below, but it is inconspicuous. Depending fertile floret is an elliptical, 13 to 15 millimeters long, formed sevenfold veined, membranous, tapered lemma without keel. The palea is about the same length as the lemma. The sterile florets growing at the tip resemble the fertile ones, but are not fully developed. Three cavernous bodies , three stamens and three stigmas are formed per flower . The fruits are caryopses with adherent pericarp and a tip without appendages.

distribution

The species is native to Japan and is also cultivated in the United States and New Zealand.

Systematics

Pleioblastus viridistriatus is a bamboo - type from the genus Pleioblastus that the tribe Arundinarieae is attributed to the woody bamboo species of the temperate climate zones. It was first described in 1866 by Eduard August von Regel as Bambusa viridistriata ( Basionym ) and placed in the genus Pleioblastus by Makino Tomitarō in 1926 . It is often assigned to the genus Arundinaria under the synonym Arundinaria viridistriata .

use

In Central Europe, Pleioblastus viridistriatus is used in beds, as border plantings or as a container plant. Its luminous foliage, which falls off in winter and is damaged in blazing sun, is striking. The species tolerates frost down to about −22 ° Celsius.
