Watering correctly is the key to keeping these small flowering shrubs at their best. They need regular irrigation but must dry out a bit in between watering. With exquisite butter-yellow flowers over glossy deep green foliage, they can work as a front-of-the-border plants or use them behind annuals, groundcovers or small perennials. Dwarf Allamandas grow at a moderate rate and you can easily keep them 2 to 2-1/2 feet tall. Plant in a full to partial sun location to get the most bloom.
