Care and Culture Card
See basic growing conditions and care information below.
Grow plants of Grosourdya on small slabs with a pad of moisture-retaining material at the roots. Provide warm temperatures, medium light levels, and regular watering throughout the year. Plants of Grosourdya typically produce sideshoots eventually forming clumps. These clumps, with each stem producing multiple inflorescences, produce miniature specimen plants despite the short-lived flowers.
