Fertilizer

Pruning Information
ʻIlieʻe tolerates heavy pruning. Trim to keep confined to planting area and to encourage branching. The plants can be formed and managed as a low hedge, or allowed to grow as a free form low shrub in larger areas. [David Eickhoff, Native Plants Hawaiʻi]

Special Features and Information
General Information
ʻIlieʻe belong to the Plumbago or Leadwort family (Plumbaginaceae) consisting of ten or more species. Plumbago zeylanica is the only native species in the Hawaiian Islands.
Apparently the Cape plumbago (P. auriculata), popular in Hawaiian landscapes, is naturalized in Keokea, below the Hana Hwy., East Maui. This species is a native of South Africa.
Etymology
The generic name Plumbago is derived from the Latin plumbum, lead, and agere, to convey, possibly to due the gray color the roots imparts when handeled.
The specific epithet zeylanica is from the Latinized name for Sri Lanka (Ceylon). [3]
Hawaiian Names:
Hilieʻe means to "stain dark brown." [4]
Lauhihi is a Niʻihau name for this plant.
Early Hawaiian Use
Medicinal:
The roots ofʻilieʻe are toxic, though, less than the red or blue flowered introduced species. But it was still used by early Hawaiians in small amounts to relieve toothaches or as a tonic. [1,4]
A poultice made from pounded bark, leaves and roots were applied to swollen body parts. The leaves and stems were made into a paste and put on sores. [2]
The dark sap was also used as a type of "baby medicine." [4]
Tatoo:
The sap was used by early Hawaiians for tattoos with hues ranging from navy blue to black. [4]
