A dwarf dahlia is Figaro, with double and semi-double blossoms. The bedding plant runs the gamut of color, from red to pink to orange to white with variations on each shade. In Maine, it will prefer full sun and well-drained soil, along with regular deadheading. The plant will produce a tuber, which can be lifted in the fall and stored over the winter. Figaro only grows about a foot tall, keeping a compact shape and making itself ideal for using containers, as well.
