Answer: Thanks to Carole Ottesen's great book, "Ornamental Grasses" (McGraw-Hill, Inc.; ISBN 0-07-048021-4), I've found a few tall, hardy grasses for you to investigate. I don't know if you can find a grass that doesn't blossom, but you can cut them out if you wish. Miscanthus sinenis condensatus is a very natural looking grass, a good foil to your rock wall. Others to consider are Giant Reed (Arundo donax -- marginal in zone 5) and Giant miscanthus (M. floridulus -- zone 6). Perhaps with rich soil, plenty of moisture, and the microclimate created by your south-facing rock wall will keep it protected in winter. A heavy dose of mulch in fall will help immensely. If you can't find these grasses locally, try Kurt Bluemel, Inc., 2740 Greene Lane, Baldwin, MD 21013; ph# 301-557-7229; http://www.bluemel.com or Shady Oaks Nursery LLC, P.O.
