Pris per förpackning av 10 frön.

Kultur

Det är väldigt lätt att växa, det behöver medium fukt, väl läckande jord i full solstråle eller delvis skugga. Det är tolerant för ett brett sortiment av jordtyper från högtorkad sandjord till lerajord. Föredrar fuktig jord. Det växte bäst när det har fullt solljus. Mindre utvecklas under förhållandena av total frånvaro av solljus, blommar inte nog och har en tendens att torka. Det är tolerant mot hög värme och hög luftfuktighet. Löv i marken bör skäras på sen vintern, precis före utseendet av nya lakan.

Betydande egenskaper

Miscanthus sinensis, som ofta kallas kinesiskt silvergräs eller japanskt silvergräs, växer vanligen från 150 cm till 210 cm. Den härrör från de lägre regionerna Japan, Korea och Kina. Det är nu representerat i olika områden och mark.

Detta gräs har tätt grupperade löv och stjälkar, vilket ger den en rundad utseende som fontänen. Bladen är raka och har spetsiga tips, vita eller silver, skarpa kanter. Bladen är attraktiva nyanser av gul till orange tills hösten och sedan gradvis blek i beige färg till vinter. Rosa eller röda blommor, fjädrar form, blommar från augusti till oktober. Blommor blir gradvis beige i slutet av hösten som frön mognar. Och blomman och löven behåller en vacker dekorativ form under vintern, vilket kan ändra snön som faller. Zebra gräs är lätt fördelat, ofta hittas längs kanterna på vägen, järnvägen eller i slutet av skogen.

Zebrinus är känt som sebragräs, format i en gruppform, känd för horisontellt förbundna löv. Dess typiska form är löv i gruppen och blomstringarna stiger ovanför bladen upp till 60 cm, vilket resulterar i gräsens totala höjd i blommande upp till 240 cm. Karaktäristika för mörkgröna blad är gyllene gula remsor som passerar horisontellt över arket med ojämna mellanrum (Zebra`s ränder). Bladen smälter gradvis efter frost. Blommorna är rosa nyanser och förekommer i slutet av året, de växer över bladen, och i slutet av höstfärgerna ändras till silverfärgat. Blomman överlever väl under vintern så att hela växten fortfarande har ett vackert och dekorativt utseende.

Det finns inga vanliga problem med insekter och sjukdomar. På vintern kan det vara nödvändigt att skydda den vid kraftig snö eftersom den har en tendens att böja sig till marken.

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.
