Semi di Erba di Zebra (Miscanthus sinensis Zebrinus)

Prezzo per Confezione da 10 semi.

Cultura

È molto facile da coltivare, ha bisogno di umidità media, terreno che perde molto in pieno sole o in ombra parziale. È tollerante su una vasta gamma di tipi di terreno, dal terreno sabbioso altamente essiccato al terreno argilloso. Preferisce terreno umido. Cresce meglio quando ha la piena luce del sole. Meno si sviluppa nelle condizioni di totale assenza di luce solare, non fiorisce abbastanza e ha la tendenza ad asciugare. Tollera calore elevato e alta umidità. Le foglie nel terreno dovrebbero essere tagliate nel tardo inverno, poco prima della comparsa di nuovi fogli.

Caratteristiche significative

Il miscanthus sinensis, spesso noto come erba d'argento cinese o erba d'argento giapponese, di solito cresce da 150 cm a 210 cm. Proviene dalle regioni inferiori del Giappone, della Corea e della Cina. Ora è rappresentato in varie aree e terreni.

Quest'erba ha foglie e gambi densamente raggruppati, che gli conferiscono un aspetto arrotondato come la fontana. Le foglie sono dritte e hanno punte appuntite, biancastre o argentate, spigoli vivi. Le foglie sono attraenti sfumature dal giallo all'arancio fino all'autunno e poi gradualmente sfumano di colore beige fino all'inverno. Fiori rosa o rossi, forma di piume, fioriscono da agosto ad ottobre. I fiori diventano gradualmente beige alla fine dell'autunno quando i semi maturano. E il fiore e le foglie mantengono una bella forma decorativa durante l'inverno, che può cambiare la neve che cade. L'erba di zebra è facilmente distribuita, spesso trovata lungo i bordi della strada, della ferrovia o alle estremità della foresta.

Zebrinus è noto come erba di zebra, formata in una forma di gruppo, nota per le foglie collegate orizzontalmente. La sua forma tipica è costituita dalle foglie del gruppo e gli steli dei fiori si innalzano sopra le foglie fino a 60 cm, determinando l'altezza complessiva dell'erba in fiore fino a 240 cm. Le caratteristiche delle foglie verde scuro sono strisce giallo dorato che si incrociano orizzontalmente lungo il foglio a intervalli irregolari (strisce di Zebra). Le foglie svaniscono gradualmente dopo il gelo. I fiori sono sfumature rosa e compaiono alla fine dell'anno, crescono sopra le foglie, e alla fine dell'autunno i colori cambiano in bianco argenteo. Il fiore sopravvive bene durante l'inverno in modo che l'intera pianta abbia ancora un aspetto bello e decorativo.

Non ci sono problemi comuni con insetti e malattie. In inverno, potrebbe essere necessario proteggerlo in caso di forte nevicata perché ha la tendenza a piegarsi al suolo.

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.
