Sounds too big for me.
I would skip the background then and secure the plant onto something solid, then use a tripod. My worst pics are when I try to hold a plant. I jiggle like mad. Also when I hand hold in lower light I see my potential for tremor hands. Nothing like taking pics in short increments to reveal our lack of a steady hand. And it seems the better the camera, the more sensitive to jiggling! Even with all the stabilizers! The more I spend, the more I use my tripod.
