What PERENNIAL GRASSES (MAX of 3' to 4') with attractive plumes at the top grow best on Nantucket? They would be planted in front of hydrangeas in front of a house. Your suggestions are?

We sell a wide variety of grasses, of varying sizes. Pennisetum alopecuroides, Fountain Grass gets about that size and has fuzzy, bottle-brush-looking flowers in late summer and fall.

I would strongly suggest you ask the professionals at Surfing Hydrangea Nursery. They're the best!
