Varieties of Hydrangeas

Hydrangeas grow in a wide area of the United States, and need care depending on the location. Protect the plants in the north from harsh winter winds so the buds for next year's flowers will survive. Plant the shrubs in partial shade in the south where the plant gets sun in the morning and shade in the hot afternoon. Treat them right and the hydrangeas will reward you with blooms from spring through summer and, hopefully, into the fall.
