Kefersteinia graminea, the Grass-like Kefersteinia, is native to South America. It is a warm- to cool-growing epiphyte with no pseudobulbs; therefore, Kefersteinia likes to stay moist. In summer, Kefersteinia graminea produces showy yellow flowers with maroon spots that emerge from the base of the plant. Despite their delicate appearance, the flowers are quite long lasting. I have found that when people see this plant in bloom, they want the plant. Period.
Kefersteinia is a Zygopetalum relative, but I find them much easier to grow than Zygopetalum. The great thing is that they have really showy flowers like the zygos. I have them growing both in pots and mounted and in very low as well as moderate light. That tells you they are tolerant of a lot of conditions. To get the best growth and blooming, grow in moderate light and keep moist.
