List Flowers

1. Oleander

  • Botanical name: Nerium oleander
  • Plant Class: Perennial
  • Bloom time: Summer

The Oleander plant is a great natural windbreaker, in addition to its tolerance of poor conditions, which is why it is a favorite in parks, gardens, and roadsides. What makes this plant astonishing, however, is its showy blossoms of red, pink, and white, and yellow that look, interestingly, like roses. Don’t be fooled, though. As roses may have thorns, the Oleander has poison in its proverbial veins, and it’s highly toxic to both humans and animals.

Due to its hardiness and toxicity, the oleander has come to symbolize power, endurance, and a spirit that never gives up in spite of hardship.
