This flowering tree is native to Hawaii, and is one of the main trees that grow out of the lava rock environment of Hawaii and its surrounding islands, playing a massive role in establishing a native forest of trees that can withstand rocky soils.

They are more common on the big island however, due to its open lava terrain and large landmass.

You can find them in a wide variety of colors such as dark red, orange, pink, purple, white, and yellow as well as a range of hybrids in even brighter colors. These are often grown in gardens and used to decorate leis.

22. Spathodea Campanulata – African Tulip Trees

It is a perennial evergreen tree that is considered invasive and can be found in a variety of Hawaiian environments, including wet and lower elevation areas.

23. Yellow Tabebuia

Final Thoughts

All the trees and flowers we’ve mentioned grow well in Hawaii. Some trees are deciduous while some will remain evergreen.

If you would like to grow a flowering tree in your own garden you need to take your location and environment into account, as well as the growing habits and conditions of the tree or flower you wish to plant.

A lot of these plants can grow very large so considering how much space you have and having sufficient rooting area away from rock walls and foundations is also important to ensure your flowering tree can grow properly and so the rest of your garden isn’t affected!
