Welp there are a few I'm gonna change and answer all to make things clear
Can she grow plants anywhere ? Yes and no at the same time, she only manipulates and clones the DNA and cells of plants which in particullar would be more of "creating" plants not "grow" and this would answer the out of thin air question as well , and here's where the "no" comes in since she clones every trait the plant has doesn't mean the plant can live at a certain area forever, for example a she grows a tropical plant in an unsuitable habitat it can't stay there forever, Does she needs material ? Yes, she can create another plant by having their cells nearby for example if she's near a Rose, a Tulip and a Daisy, she can create those three since they are the only nearby, so if she's in a place with literally no Floral lifeforms then she can't use her powers, but of course she can save a cell of a plant for a mater of time before it dies out too. Can she grow fictional plants ? Kinda, since she clones the plants, she can alter their DNA but only the fact that she can't change them to fictional plants but she can change their size.
I hope that cleared up some info
