Bougainvillea

Bougainvillea is another beautiful trick of the eye. Those magenta, coral, and white “petals” are papery bracts; the real flowers are the small cream trumpets tucked at their centers. The bracts stay colorful for weeks, which is how a single vine can look like it is blooming all summer.

It loves what most flowers hate — heat, poor soil, and neglect. Water it too kindly and it grows leaves instead of color. Along Hawaiʻi's dry leeward coasts it climbs walls and spills over rooftops in sheets of impossible pink.

The plant carries thorns beneath all that softness, a fair reminder that toughness and beauty are not opposites.
