Bloom. All months in which we can find blooming specimens. Regional differences may occur.
Harvest Time. All months in which we can find ripe fruits on trees. Unripe fruit can be found earlier on trees and shrubs. Sometimes even throughout the year, as happens with trees such as pines, this fruit ripens over several years.
Both flowers and ripe fruit may occur at the same time in some months.
