Hawaii is known for its beautiful beaches of white sands, exotic wildlife, amazing weather, and also its stunning native plants. It’s one of the most popular tourist locations in the United States and it’s also the only U.S. State that is not actually part of North America. There are many things to love about Hawaii and the weather and the plant life are just the beginning.
Our Hawaii native plants list will help you learn more about the plant life found on the islands and how to choose the best native plants for your garden or landscaping needs. Let’s take a look at how the unique climate range of Hawaii leads to the diverse plant life found on these beautiful tropical islands.
Unique Climate of Hawaii
Hawaii has a unique climate that hosts the many beautiful plants and flowers you will find on this list. It has ten of the world’s fourteen climate zones and you can visit them all on Hawaii Island. The other islands have different climate zones spread throughout them.
It is the only place on earth with so many concentrated climate zones in one area, and this lends itself to a really interesting array of plant life and wildlife that occur here. And remember, when you use native plants in your garden and landscaping, it benefits the local ecosystem.
So, which climates can you find here on Hawaii Island? According to a 1978 report by a trio of University of Hawaii geology professors, these are the climates/zones you can find.
A. Humid tropical climates
- Tropical Continuously Wet (Af)
- Tropical Winter-Dry (Aw)
- Tropical Summer-Dry (As)
- Tropical Monsoon (Am)
B. Arid and semi-arid climates
- Hot Semi-Desert (BSh)
- Hot Desert (BWh)
C. Temperate climates
- Continuously Wet Warm Temperate (Cfb)
- Summer-Dry Warm Temperate (Csb)
- Summer-Dry Cool Temperate (Csc)
E. Ice climates
- Periglacial Climate (ET)
You can find tropical climates with various humidity and a hot season from June to October on the main island. There’s a cool season from December to March. And mid-January to mid-April is actually the coldest time on the island. In November through February, you’ll see the biggest waves on the north shore of the island. And on the highest summits – Mauna Kea and Mauna Loa – you can even find snow. It’s no surprise then, with these very diverse climate zones, that there will be a lot of variation in plant life. Plants that are found on the coast can be completely different from those more inland or those in high elevation, for example. Understanding your climate zone is important to choose the right plants.
Hawaii Native Plants List
Aloha means “love” and we know you’re going to love these great Hawaiian plants. Here are some top picks for native plants that will look beautiful in your garden:

What about plumeria?
Tuesday 6th of December 2022
Gloria, plumeria is not native to Hawaii.

Some lovely flowers and foliage however the Hibiscus brackenridgei depicted is not Hibiscus brackenridgei. It's a common garden cultivar of Hibiscus rosa-sinensis, thought to originally come from China. That's to say not all yellow hibiscus on Hawaii are H. brackenridgei. Brackenridgei is very easily recognised as it has "deeply lobed" (like a grape-vine leaf) leaves that are also rough textured, matt and fuzzy. Rosa-sinensis has entire toothed leaves glossy or shiny. The flower is also completely different, here also in colour of the centre. There are of course many other simple morphological differences between the two species but already from the leaf we can very safely ascertain the picture is incorrect.
