Plants from at least 100 genera and 1000 species are grown as foliage plants.
These plants have widely diverse forms, patterns of foliar variegation, and colors. Based
on their appearances, foliage plants can be simply categorized into three groups: greenleaf,
variegated-leaf, and flowering foliage plants. How these groups of the plants respond
to interior low light conditions has not been previously documented. The objective of this
report is to summarize our recent investigations on how representatives of these three
plants categories responded to interior low light environments.
