It's a Cleome, an annual plant. They don't transplant well so let it grow there if you can, harvest the seeds when they ripen (it can be tricky, they pop open when ripe) and broadcast them where you want them, they can also be winter sown. They tend to reseed heavily.

If those are its leaves below I'd go with Erodium. Given your location try E texanum.

Maybe Erodium texanum?

Hawaii has had all sorts of issues with newcomers. Between the rats, mongeese, pigs, fire ants, assortment of invasive plants, and humans, the islands are all sort of a disaster. Even (or especially) the waters around the islands are in bad shape, and not just from coral bleaching. Peacock grouper and various non-native snapper have wreaked havoc on the smaller reef fishes. The native islanders must continue to be forlorn about the state of their homeland and how quickly it’s changing.
