Jeanne Sammons This is my favorite grass … it puts on a show all Winter. Right now it’s wet and a bit droopy … but it perks right back up after snow coverage and sunshine in the Winter!
Jeanne Sammons’s Miscanthus in an Iowa Winter
“I don’t cut it back before Winter,” says, Jeanne…”my grasses get cut back in the Spring before the new growth is too far along…love the grasses blowing in the Winter winds!”
Miscanthus does well in heat, Jeanne says.
“I planted one in a container cause I thought that would be cool, but it was good for only two years before the pot cracked in two due to fast growth and Winter chill. One I also tried to take out of the pot for over Winter and the roots were so huge that I broke the pot myself trying!” Jeanne says.
