How To Identify Common Wildflowers In Hawaii

Identification can be tricky because many flowers look similar. Here is a step-by-step process to help you.

Look at the flower shape. Is it a single flower or a cluster? Is it trumpet-shaped, star-shaped, or like a pom-pom?
Check the leaf shape and arrangement. Are the leaves opposite each other or alternating? Are they smooth or hairy?
Note the plant’s habitat. Is it growing in dry sand, wet forest, or high elevation? This narrows down the possibilities.

Take a photo and compare. Use a field guide or a plant identification app to confirm.
