Ann, your First Frost is lovely. I have it as well as Autumn Frost but they need a few years to develop yet. Both are planted in an south east facing bed that get quite a bit of sun especially in the spring before the ash trees leaf out; their colour looked a little faded last year so hope they will adjust. June is in that bed as well and has more of the yellow colouring in that position. I do love the more bluer coloration of June in the shade so plan to get another or a division for a more shady spot.
