Zebra Grass Runners?
In July of 2004 I planted Miscanthus sinensis 'Little Nicky' (dwarf zebra grass). The plant has grown to between 5 and 6 ft. tall but hasn't bloomed yet. A month or two ago I noticed a small clump of grass growing about 3 ft. from the grass I had planted. Now it is nearly 3 ft. tall and has a growth habit and leaves that look very similar to dwarf zebra grass. However, it has no stripes as yet. Does dwarf zebra grass send out runners? If so, will the new plant eventually get its stripes? If it does send out runners, does this happen very often? Is its spread difficult to control? It would be rather inconvenient to have zebra grass popping up in the middle of my other perennials. Has anybody had experience with this?
Thank you for any wisdom you might be able to impart.
