I’ve had some experience with polygala indoors, and I found it does best with plenty of bright, indirect light—direct sun can scorch its leaves quickly. Make sure the potting mix is light and well-draining; a blend of peat, perlite, and a bit of sand usually works well. Water moderately, allowing the top inch of soil to dry out between sessions, and avoid letting it sit in waterlogged soil. These tweaks have helped my plants thrive even in an indoor setup.
