I'm helping a friend with her back yard (Z5) she would like to plant some tall grasses. I have very little knowledge of grasses, since my thought is they need sun. The only grass I could think of is Hakonechloa and that's a short one. Are there others that are tolerant of shade?
Chasmanthium latifolium is about the tallest grass which will grow in shade in zone 5. It'll hit 4'+ to the seedheads as long as it has moist soil. It's sometimes called Northern Sea Oats, or Wild Oats. It'a a very nice bamboo-looking plant.
If it's less than full shade, like light shade or part shade, there are lots of other choices. Take a look at the comparative chart at Bluestem.
Donn, Thanks that is an excellent chart.
I would say the area she is looking at is part shade.
Some how I posted a duplicate thread, which I had the administrations of DG remove, I am sorry for the confusion and to those who posted to the other thread. If I remember correctly they were in agreement about the suggested grass.
