Fenestraria rhopalophylla subsp. aurantiaca, also known as Fenestraria aurantiaca, is a small stemless succulent with green, club-shaped leaves that form a mat. This succulent is a geophyte, meaning that it has underground storage organs where it stores water and energy. It has small 'windows' in the top of its leaves to let in light. Bright yellow flowers on long pedicels bloom from late summer / autumn to spring.
This plant needs a lot of light, place in full sun with some shade from the summer afternoon sun. Ensure the potting mix is very well draining and the container has good drainage. Most problems with this plant occur due to over or under-watering. Water during the growing season, making sure that it completely dries out quickly, especially when the weather is cold or damp. Water minimally during summer when it is dormant (when it starts to look a bit shrivelled).
