G Figure H Paul James, host of HGTV's Gardening by the Yard , shares a list of some of his favorite spring-blooming plants. They are the state flower of Colorado and perform well in cold climates. They grow easily from seed, and established plants may be divided to increase your stock. They require partial shade in hot climates, regular water during the growing season and a fast-draining soil.
Azaleas grow best where they receive afternoon shade and prosper in well-mulched acidic soil.
Azaleas should be fertilized just before they bloom. In the North most can be grown in full sun. Various species produce white, pink, yellow or purple blooms. Today more than 500 varieties are available in the United States in a range of colors including white, pink, red, lilac and blue. Dazzling white flowers are also produced by fothergilla, a deciduous shrub related to witch hazel.
