Frank,
The Adagio Miscanthus you mentioned is a great selection, I am not as familiar with ‘Yaku Jima’. But if your looking for alternatives, try Pennisetum (a.k.a. Fountain Grass) and a smaller variety is known as ‘Hameln’. Or, Calamagrostis x ‘Karl Foerster’ a more upright selection.
Check out Greanleaf Nurseries website’s product search (http://www.greenleafnursery.com/search.asp). They have pictures and detailed info. about many plants and they have superb quality if your looking to order.
Stay Creative,
Bill
