A rare twisted-root cactus, the Fockea makes an interesting addition to your plant collection. They can tolerate full sun but prefer partial shade, as their small branches can burn in full sun for too long. Allow the soil to completely dry between waterings, and water less in the winter. They will bloom with white flowers when happy, and it's natural for them to drop leaves in the winter, though they shouldn't lose all of their leaves.
These plants come in 6" pots.
