I grow whats called an orchid cacti.has flat leaves and has sprouts
growing off them.not actually the same as the flat leaves.its a cutting& had already learned would take about 2 years for it settle in and bloom..possibly a color of pink.
I also grow some "stubs "of night blooming cerus.not bloomed yet.were divions I believe.
Look at this 2nd pic!I would just love to move that very
plant to beside my pond.
