About 12-18" tall. Thanks.
There are too many to list. You'll have to narrow it down;
Bloom type and color?
Habit and shape of the plant?
Soil type and moisture content?
Cool or warm season?
There was a photo. I've tried sending it again.
That's one of the cultivars of Hakonechloa macra, AKA Japanese Forest Grass, IMO, one of the most beautiful OGs out there.
