bought five recently, perfect for semi shaded patio, wonderful color, very gold, not yellow, gold. But now after about a month there is a greenish cast to them, a bit like mildly tarnished brass........any ideas??????? I wondered if the cause could be that I did dig in a bit of all purpose fertilizer in each hole when I transplanted. Could that possibly be the cause? I have added nothing else to the area and have kept them adequately watered. Appreciate any info, thank you

Found on another site: They produce the brightest yellow-gold foliage in partial or dappled shade, but will also grow in full shade where the color fades to lime green. The color bleaches to creamy white when grown in full sun in cool summer climates (in hot climates they tend to burn in full sun). In the fall, the foliage takes on an orange to reddish cast, then turns light brown before collapsing in winter. Unlike many other ornamental grasses, this species does not remain standing to provide interest in the winter, but dies back to the ground.
Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed.

The color change is normal. Spring growth will always be more yellow, and depending on the conditions where you grow them, the color change intensity will vary. High nitrogen (lots of fertilizer) can encourage a more green color. Unless you are growing them in pots, they shouldn't need fertilizer if they are in good soil.
