12. Rhododendron
There are more than 1000 species of Rhododendron in Europe, North America, Asia, and Australia. We need good drainage soil and a cool climate to grow at our best. You can find these flowers in the wild, especially in tropical rainforests, mountains, and temperate forests. They have a height from 4 inches to 98 feet, option into the type.
They have evergreen leaves or funnel, bell, trumpet flowers. Many people call Rhododendron a rose tree because some of their flowers remind us of roses.
