Meet Hawaiʻi’s Plants

If you’re researching plants in Hawaiʻi, start with our species profiles for canoe plants and common native species. Each profile has information about distribution and life characteristics, with references for further learning. Once you’ve checked out those species, you can learn about Hawaiʻi’s rare plants or landscaping plants with the GoNative or Plant Pono resources below.

Plants in Hawaiʻi: Species Profiles

Go Native: Choose native plants for landscaping

This site helps you pick native species and Polynesian-introduced plants for landscaping based on your specific climate and growing conditions. By growing these species across our communities, we can create kīpuka for other native species to use as habitat and food for Hawaiʻi’s people. Go Native is a project of the Hawaiʻi Forest Institute and Grow Good Hawaiʻi.

Plant Pono: Find alternatives to invasive plants

Plant Pono uses the Hawaiʻi-Pacific Weed Risk Assessment to determine how likely a plant species is to be invasive in Hawaiʻi. If you’re thinking of planting a particular landscape species, check it out on Plant Pono first. If it’s likely to be invasive, Plant Pono will suggest alternatives for you that are a better fit for Hawaiʻi.

ʻŌhiʻa Finger Puppet Craft

Your students can become the community forest when you download and print this easy craft activity. Each student will cut and tape together a single ʻōhiʻa lehua blossom that will perch on their finger. If you’d like to add to your forest, you can have some of your students create native bird finger puppets that can visit the ʻōhiʻa lehua for nectar. This is a great opportunity to discuss as a class how having more ʻōhiʻa and other native plants in our communities could help create more habitat for our native animals.
