Additional Landscape Use Information

Though this lysimachia is a perennial, it sometimes grows more like an annual. So it is best to collect seeds for future propagation or they will reseed on their own if the area is moist. With sufficient watering this species does well in clay, cement or hanging pots on a sunny lānai. [David Eickhoff, Native Plants Hawaiʻi]

leaf Special Features and Information

General Information

Recently the genus Lysimachia has been placed in the Myrsine family (Myrsinaceae).

To date, there are thirteen endemic and one indigenous species native species in the Hawaiian Islands.



The generic name Lysimachia is derived from the Greek lysis, release from, and mache, strife. Tradition relates that when Lysimachus, King of Thrace in Asia Minor (306-281 BCE), was chased by a bull he waved a plant of this genus to pacify the animal, thus releasing himself from strife. The common name for plants in this genus is loosestrife.

The specific epithet mauritiana refers to the island of Mauritius.

Background Information
