Dwarf flowering plants are plants that are either genetically smaller or those that are smaller because of grafting or pruning and restricting the root growth. Dwarf flowering plants can be annuals, such as the "floral showers" variety of snapdragons, or perennials, like the dianthus variety "microchips." Whatever variety of dwarf flowering plant you grow, you'll be rewarded with a plethora of blooms in a minimal amount of space.
