Graines de Herbe de Zèbre (Miscanthus sinensis Zebrinus)

Graines de Herbe de Zèbre (Miscanthus sinensis Zebrinus)

10 graines par sachet.

Culture

Il est très facile à cultiver, il a besoin d'humidité moyenne, de sol bien fuyant en plein soleil ou à mi-ombre. Il tolère un large éventail de types de sols, du sol sableux fortement sec au sol argileux. Préfère un sol humide. Il a grandi mieux quand il a plein soleil. Moins se développe dans les conditions d'absence totale de lumière du soleil, ne fleurit pas assez et a tendance à sécher. Il est tolérant à la chaleur élevée et à l'humidité élevée. Les feuilles dans le sol doivent être coupées à la fin de l'hiver, juste avant l'apparition de nouvelles feuilles.

Caractéristiques significatives

Miscanthus sinensis, souvent connu comme l'herbe d'argent chinoise ou l'herbe argentée japonaise, pousse généralement de 150 cm à 210 cm. Il provient des régions inférieures du Japon, de la Corée et de la Chine. Il est maintenant représenté dans diverses régions et terres.

Cette herbe a groupé les feuilles et les tiges, qui lui donnent un aspect arrondi comme la fontaine. Les feuilles sont droites et ont des pointes pointues, blanchâtres ou argentées, avec des arêtes vives. Les feuilles sont d'une nuance attrayante de jaune à orange jusqu'à l'automne et ensuite progressivement pâle de couleur beige à l'hiver. Des fleurs roses ou rouges, en forme de plumes, fleurissent d'août à octobre. Les fleurs deviennent progressivement beige à la fin de l'automne à mesure que les graines mûrissent. Et la fleur et les feuilles conservent une belle forme décorative durant l'hiver, ce qui peut changer la neige qui tombe. Le zèbre est facilement distribué, souvent sur les bords de la route, du chemin de fer ou aux extrémités de la forêt.

Zebrinus est connu sous le nom de zèbre, formé en forme de groupe, connu pour les feuilles reliées horizontalement. Sa forme typique est constituée de feuilles dans le groupe et les tiges de fleurs s'élèvent au-dessus des feuilles jusqu'à 60 cm, ce qui fait que la hauteur totale de l'herbe peut atteindre 240 cm. Les caractéristiques des feuilles vert foncé sont des bandes jaunes dorées qui traversent horizontalement la feuille à intervalles irréguliers (bandes de Zebra). Les feuilles se fanent progressivement après le gel. Les fleurs sont roses et apparaissent à la fin de l'année, elles poussent au-dessus des feuilles, et à la fin de l'automne les couleurs changent en blanc argenté. La fleur survit bien pendant l'hiver de sorte que la plante entière a toujours un aspect beau et décoratif.

Il n'y a pas de problèmes communs avec les insectes et les maladies. En hiver, il peut être nécessaire de le protéger en cas de neige abondante car il a tendance à se plier au sol

ORIGINAL TEXT:

Culture

Easily grown in average, medium moisture, well-drained soil in full sun to part shade. Tolerant of a wide range of soils from well-drained sandy soils to the heavy clays present in much of the St. Louis area. Prefers moist soils. Best in full sun. Less vigorous with decreased flowering and tendency to flop in too much shade. Tolerant of summer heat and humidity. Clumps slowly expand in circumference by short rhizomes, but typically retain tight clump shape. Foliage should be left standing throughout the winter for visual interest and crown protection. Cut foliage close to the ground in late winter just before new shoots appear. Propagate by division of the crown. This grass will reseed to the point of being somewhat invasive in the milder parts of its growing range. Mulch helps prevent reseeding.

Noteworthy Characteristics

Miscanthus sinensis, commonly known as Chinese silver grass, Japanese silver grass or eulalia grass, is a clump-forming warm season grass that typically grows to 3-7’ tall. It is native to lowlands and lower alpine areas in Japan, Korea and China. It has escaped gardens and naturalized in over 25 states in the Central and Eastern U.S. east of the Mississippi River plus in several western States including Colorado and California.

This grass features a dense clump of upward-arching stems and leaves which give it a rounded, fountain-like appearance. Linear leaves (to 3-4’ long and 3/8” wide) have tapered tips, serrate margins and whitish to silvery midribs. Foliage often turns attractive shades of yellow to orange by mid-fall before gradually fading to beige-tan for winter. Pink to red flowers in feathery, whisk-like, loose terminal panicles (8-10” long) bloom above the foliage from late August to October. Flower panicles gradually turn beige by mid-fall as the seeds mature. Flower panicles and foliage both retain good arching shape, beige color and ornamental interest throughout winter, with enhanced attractiveness often coming from a covering of new fallen snow.

Miscanthus sinensis will spread somewhat invasively in the landscape, particularly in some of the milder areas of its growing range. It often initially spreads to disturbed sites such as roadsides, railroad right-of-ways or woodland margins. Invasive potential for the species is significant, but is of less concern for many of the numerous ornamental cultivars, some of which are sterile.

Genus name comes from the Greek words miskos meaning a stem and anthos meaning flower in reference to the stalked spikelets.

Specific epithet means Chinese.

This grass was once included in the genus Eulalia, but was subsequently reclassified to the genus Miscanthus with retention of its common name of Eulalia grass by many gardeners.

'Zebrinus', knows as zebra grass, is a clump-forming grass noted for its horizontally banded foliage which is reminiscent of both the popular M. s. 'Strictus' and M. s. 'Puenktchen'. However, 'Zebrinus' clumps are rounded, tend to flop and often need support, whereas 'Strictus' and 'Puenktchen' both feature spiky, upright leaf blades in narrower clumps which usually do not need staking. 'Zebrinus' typically forms a substantial foliage clump to 4-6' tall, however it sends up flower stalks to 2' above the foliage clump, thus bringing the total height of the grass to 6-8' tall when in flower. Features dark green leaves with zebra-striped, golden yellow bands extending horizontally across the leaves at irregular intervals. Foliage gradually fades to tan after frost. Tiny pink/copper-tinted flowers appear in tassel-like inflorescences above the foliage in late summer, gradually turning into silvery white plumes in fall. Flower plumes persist well into winter providing good winter interest.

Problems

No frequently occurring insect or disease problems. In some areas of the U.S., miscanthus mealybug and miscanthus blight are becoming significant problems. Miscanthus mealybug causes stunted growth and is difficult to eradicate because it lives inside the stems. Miscanthus blight is a fungal disease which attacks the blades and sheaths. Leaf rust may occur.

'Zebrinus' clumps may need staking and are susceptible to collapsing in winter from heavy snows.
