Additional Landscape Use Information

An excellent understory shrub for taller trees in shaded and part sun locations with moderate amounts of water. Red-veined varieties appear to handle full sun in open lowland landscapes than do green-leaved varieties. Māmaki is generally not suited for hot, dry coastal seetings. It does well in urban landscapes with some shading.

Māmaki will do well in containers in part shade and with applications of fertilizer at half strength. [5]

Additional Plant Texture Information

Māmaki leaves can range from 2 to about 12 inches long, depending on the variety and/or the origin of the plants.

Leaf Colors

  • Light Green
  • Medium Green

Additional Leaf Color Information

Māmaki leaves are light to dark green to reddish with green, pink or red veins with lighter undersides which are sometimes almost white.

leaf Pests and Diseases

Additional Pest & Disease Information

Plants are prone to ants, scale, mealy bugs, thrips and aphids. Chinese rose beetles, caterpillars and grasshoppers make holes in the leaves but usually do not affect the overall health of the plant if damage is minimal. Spittle bugs and aphids may attack new growth but are seldom a major problem. Fungal disease can attack and kill young plants.

leaf Growth Requirements

Fertilizer

Māmaki benefit from an application of a balanced slow release fertilize with minor elements every six months. Foliar feed monthly with kelp or fish emulsion, or a water-soluble fertilizer with a dilution of one-half to one-third of the recommended strength. [David Eickhoff, Native Plants Hawaiʻi]

Pruning Information

Pinching the growing tips of māmaki regularly will encourage new growth. Plants prune well and can be done to keep leaves within reach for harvesting. Do not remove more than 1/4 of the leaves off the plant at a time.

Water Requirements

  • Moist

Additional Water Information

Māmaki require moist to wet conditions at the roots.

Soil must be well drained

Yes

Light Conditions

  • Full sun
  • Partial sun

Additional Lighting Information

Māmaki varieties with red coloring in the leaves do fine in full or partial sun locations. Green-leaved varieties will tolerate full sun when established, but prefer partial sun to shadier conditions. In shadier areas, the plants will look less stressed and the leaves tend to grow larger.

Spacing Information

Plants should be spaced 6 to 8 feet apart.

leaf Special Features and Information

General Information

Māmaki are members of the Nettle Family (Urticaceae). But unlike its mainland relatives, these gentle natives have no painful stinging hairs.

Māmaki is one of the best native plants to attract one of only two native butterflies Pulelehua Kamehameha or Kamehameha butterfly (Vanessa tameamea)--a good reason not to spray insecticides on the plants.

Early Hawaiian Use

Early Hawaiians used the wood to make clubs and kapa beaters (iʻe kuku). [6]

Mothers gave the small white fruit to children as a mild laxative. [1,4] Seeds were given to infants for general debility of the body. [6] Women ate fruits and seeds during the later months of pregnancy. [1,6] The fruit was also used in healing sores and wounds. [4]

The sap mixed with water was used to keep the kapa wauke moist in preparation process. [1] But māmaki itself was an important source of for kapa. [7] The inner bark was made into a brown colored kapa when wauke was not available. The kapa quality was said to be very good and fit for a king! [1]

Modern Use

Dried or fresh māmaki leaves are used to make a mild but invigorating and healthy tea and one few commercially available native herbs for consumption. The tea helps with listlessness. Māmaki leaves generally have a more pleasant aroma and taste than koʻokoʻolau. [2] The fresh or dried leaves for mamaki tea have been used to help with many internal disorders such as for the stomach, colon, bladder, liver, and bowels. [3]

The leaves and bark of two varieties, mamaki keʻokeʻo and mamaki ʻulaʻula, were consumed and recognized as "greatly desired by the Hawaiians." There were no medical complications, with "both of them a blessing for those who are weak and frail." [8]
