Flowers may be pink, red, white, single to semi-double and very free flowering For many years begonias were only considered pot plants.
Many types still fall in that category.
Plant breeders have developed many new varieties that are adapted as pot or basket plants and for use in outdoor beds. Today's varieties of fibrous rooted varieties with small to medium sized flowers are adapted for our summer heat. However, their greatest advantage is their adaptability to either sun or shade. Our clay soils are almost void of humus or organic matter and are poorly drained and aerated. You will have to overcome these characteristics by thoroughly spading, plowing or rototilling the flower beds and adding 3 inches or more of peat moss, pine bark, or leaf mold along with one inch of coarse sand.
