The name Pachypodium brevicaule means 'thick-foot, short-stem'. It is a Native of regions of Madagascar. They can reach a diameter of more than 12 inches. They typically grow on exposed limestone rock faces. As you can see in the photo below the flowers are a beautiful clear yellow. They are a little hard to grow because they are rot-prone when not under ideal conditions. They require bright light and even moisture throughout the year. It is best not to keep dry for any length of time. It is not frost tolerant and does fine with night-time winter temperatures in the 40's and even high thirties, as long as there is bright light and 70 plus temperatures during the day.
