Answer: It sounds suspiciously like Stipa arundinacea (Pheasant?s Tail Grass). Like a fountain, the green, bronze and golden narrow blades are upright and arching. Slightly dry soils will intensify the copper tones of this graceful, clumping evergreen Stipa. While grown mostly for its delightful form and color, the subtle inflorescences appear as a fine mist, tinged with small purple and golden seed capsules known as awns.
Without knowing for certain whether this is the plant in question, I can only suggest you visit several local nurseries and try to find a match for the plant. Best wishes with your garden!
