Mini lotus A bowl featuring a single, flowering lotus plant (Nelumbo spp.) can brighten a windowsill or patio. A dwarf variety works especially well in a small-bowl water garden. One dwarf cultivar is the sacred lotus (Nelumbo â€œMomo Botanâ€), which is hardy in U.S. Department of Agriculture plant hardiness zones 4 through 10. Preparing the bowl, planting correctly and providing ongoing care encourages a lotus to bloom for two or more months.
