Choosing the right bleeding heart (Dicentra spectabilis) variety can make all the difference in your garden’s success. Different climates require different plant selections to ensure healthy growth and vibrant blooms. This regional guide helps gardeners select the best bleeding heart varieties suited to their specific climate zones.
Understanding Climate Zones
Climates are categorized into zones based on temperature ranges and seasonal conditions. The USDA Plant Hardiness Zone Map is a common reference, ranging from Zone 1 (coldest) to Zone 13 (warmest). Knowing your zone helps in selecting plants that will thrive in your environment.
