Silver Dollar Plant (Xerosicyos danguyi) are unique because they have perfectly round leaves and vining stems. These tropical vines have a few requirements in order to thrive but nothing too hard. Give them bright indirect light and water only when dry. They are usually grown as a house plant in Kansas but can be moved outside if kept in full to part shade. Leaves can sunburn but morning or filtered sun is ok! Xerosicyos danguyi is native to West and South-West Madagascar. In the wild, this species subarid bushland forest and dunes that occasionally frost. Potted plants are hardy to at least 25 degrees F for a short time if kept dry so you are ok if you miss the first light frost. Do not allow the pot with rootball to freeze solid though. Move into a cold garage, basement, or bright window over the winter with occasional watering. As a winter house plant, it will look presentable all winter long with just a few waterings. Repotting may or may not be needed depending on how large you want the plant to grow; plants can continue to grow in the same pot for years. If repotting, make sure to use a sharp draining medium organic cactus mix with plenty of sand and perlite. To play is safe, outside potted plants are best moved in before night temperatures get below 35 degrees F. It is important to avoid the combination of wet and cold. Potted plants are very low maintenance; I have never seen a pest on this plant. This is relatively rare plant never seen at the big box stores and will command a higher price than most other houseplants.
