Whereas conifers (click here) predominate in the canopy of our forests, members of the heath family dominate the understory of our forests, our wetlands, and alpine regions. This large family of plants lives in almost every part of the world. The petals of ericaceous flowers are fused at the base, usually forming a tube. They are usually pollinated by hummingbirds, bees and other insects. Most ericaceous plants are found in acidic, humusy soil and often depend upon fungal mycorrhiza for successful growth. Many genera are important in the field of horticulture.
