Azalea.
Azaleas are flowering shrubs making up part of the genus Rhododendron.
Originally azaleas were classed as a different genus of plant,
but now they are recognized as two of the eight sub-genera of rhododendrons: -
- subgenus Pentanthera (deciduous),
- subgenus Tsutsuji (evergreen).

Azaleas bloom in spring, their flowers dying only a few weeks later.
They do not need as much sun as other plants; they live near trees
and sometimes under them.

Azalea is also the flower of Sagittarius the astrology symbol.
