Pampas grass is one of those that is difficult to grow in our area because they are typically grown in the southern states and rated for a warmer zone. I have seen them adapt to our zones 5 and 5b, however, they are usually in a protected spot.
Miscanthus sinensis is another one of the popular grasses — especially “Morning Lights,” which is very common throughout our area with its large clumping habit and draping narrow green fronds.
Other picks that are quite often used are papyrus and Hawaiian hibiscus. You can add to that some interesting conversation plants, including Jacob’s ladder or agapanthus. And if one has a rocky or mulched bed, use sweet potato vine (light green, deep mahogany, or variegated), euonymus or “ice plant.”
The common sense thing is to use “low litter plants” near or around pools and ponds to keep maintenance to a minimum and more time for enjoyment.
