I brought two developed grasses last year in June in flower for £10 each and when winter came I cut out the flowers and brought a wide comb and combed them as apparently it helps them even better besides removing deadness from underneath...they're a lovely blue come evening when the sun has been on them but this year the one hasn't flowered being more in shade than sun. When I brought them 2017 This year 2018 with them trimmed
Eileen they was the best buy I brought but reading about them and their growth...splitting them in half when they're about 3yrs old does them good apparently but the blue is such a beautiful look.
