In botany, blossoms are the flowers of stone fruit trees (genus Prunus) and of some other plants with a similar appearance that flower profusely for a period of time in spring.

Colloquially, flowers of orange are referred to as such as well. Peach blossoms (including nectarine), most cherry blossoms, and some almond blossoms are usually pink. Plum blossoms, apple blossoms, orange blossoms, some cherry blossoms, and most almond blossoms are white.

Blossoms provide pollen to pollinators such as bees, and initiate cross-pollination necessary for the trees to reproduce by producing fruit.

A flag is a piece of fabric (most often rectangular) with distinctive colours and design. It is used as a symbol, a signalling device, or for decoration. The term flag is also used to refer to the graphic design employed, and flags have evolved into a general tool for rudimentary signalling and identification, especially in environments where communication is challenging (such as the maritime environment, where semaphore is used). Many flags fall into groups of similar designs called flag families. The study of flags is known as "vexillology" from the Latin vexillum, meaning "flag" or "banner".

National flags are patriotic symbols with widely varied interpretations that often include strong military associations because of their original and ongoing use for that purpose. Flags are also used in messaging, advertising, or for decorative purposes.

Some military units are called "flags" after their use of flags. A flag (Arabic: لواء) is equivalent to a brigade in Arab countries. In Spain, a flag (Spanish: bandera) is a battalion-equivalent in the Spanish Legion.
