Not Showy
Flower Colors
- Greenish-White
- Red
- Yellow
Additional Flower Color Information
Diminutive greenish or yellowish white to reddish flowers form in clusters at leaf tips.
Blooming Period
- Year Round
- Sporadic
Additional Blooming Period and Fruiting Information
Aʻaliʻi can be male or female on separate plants (dioecious) or both male and female on the same plant (monoecious). The male and female flowers are diminutive. The fruits (capsules), however, are showy and are the attractive feature of ʻaʻaliʻi. The seed capsules, only produced from female flowers, can be greenish-white, straw yellow, pink, orangish, light red, brick red, or reddish-purple, and often a mottled combination of colors.
Natural habitats such as Lānaʻi (Kānepuʻu) and some of the dry forests on Hawaiʻi Island produce some very nice low growing forms with abundant tight clusters of brilliantly colored capsules. [David Eickhoff, Native Plants Hawaiʻi]
Plant texture
- Fine
- Medium
- Coarse
Additional Plant Texture Information
Leaves range from under an inch to over 5 inches long.
Leaf Colors
- Dark Green
- Medium Green
Additional Leaf Color Information
ʻAʻaliʻi leaves can be green to green mottled with red.
Additional Pest & Disease Information
Mealy bugs can be a problem if not controlled. Black twig borers can be a major threat as well.
Fertilizer
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 recommended strength. [David Eickhoff, Native Plants Hawaiʻi]
Pruning Information
Aʻaliʻi prunes well and is very forgiving of pruning errors. Pruning encourages thicker hedges but do not prune back into old wood. Prune after fruiting to shape or keep short. ʻAʻaliʻi can be shaped into a small tree, topiary, hedge or espalier (on a trellis).
Water Requirements
- Dry
Additional Water Information
Greatly reduce watering once plants are well established.
Soil must be well drained
Yes
Light Conditions
- Full sun
- Partial sun
Additional Lighting Information
ʻAʻaliʻi becomes more tree like or leggy when grown shade with too much moisture. They prefer full sun, branching and flowering more profusely with good sunlight.
Spacing Information
Depending on variety and source, plants should be spaced 6 to 8 ft. apart. As with many native Hawaiian plants, ʻaʻaliʻi may perform differently under cultivation than in their natural habitat. [David Eickhoff, Native Plants Hawaiʻi]
Tolerances
- Drought
- Wind
- Salt Spray
Soils
- Sand
- Cinder
Limitations
Although ʻaʻaliʻi is drought tolerant, it will shed leaves in extreme drought. These shrubs have a moderate salt tolerance.
Male ʻaʻaliʻi do not produce the characteristic seed capsules which are a prominent feature in landscapes or for lei production.

Special Features and Information
General Information
The genus Dodonaea belongs to the Soapberry family (Sapindaceae) with some 70 species, 61 of which occur in Australia with 59 endemic species. Dodonaea viscosa is the only Pantropic species.
Other native Hawaiian members include two endemics māhoe (Alectryon macrococcus), and lonomea (Sapindus oahuensis), and the indigenous mānele (Sapindus saponaria).
Etymology
The generic name Dodonaea is named after the Flemish physician and botanist Rembert Dodoens (1517-1585), who was later a professor of medicine at Leiden, The Netherlands.
The specific epithet viscosa is derived from viscous or sticky.
Hawaiians Names:
ʻAʻaliʻi kū ma kua (meaning ʻaʻaliʻi standing in back), ʻaʻaliʻi kū makani (ʻaʻaliʻi standing in the wind), and kūmakani (windbreak or wind resisting).
Background Information
Aʻaliʻi is an extremely variable plant with many habit, leaf and capsule forms and colors. One can hardly say that there is a typical ʻaʻaliʻi. Three intergrading Dodonaea entities may be recognized, possibly to a species level:
(1) D. sandwicensis, found occuring in wet motane sites, have mostly 2-winged capsules. [7] This plant is the only one of the three found in wet areas. Apparently endemic to the Hawaiian Islands. [Joel Lau, Botanist]
(2) D. viscosa [syn. D. angustifolia, D. eriocarpa, D. spaulata], widespread and pan-tropic but in the Hawaiian Islands this plant is primarily found in open, mesic to dry sites on all the Main Islands. These plants have 3-4-winged capsules that are fuzzy and turgid (swollen). [6]
(3) D. stenoptera, which occur primarily on Molokaʻi and scattered sites on Oʻahu (tree-sized), have the largest capsules of the three species and are strongly inflated, 4-winged and wings are short, almost wingless. Apparently these plants are/were found on Lānaʻi and West Maui (two records). [Joel Lau, Botanist]
This is a favorite food plant for the Blackburn butterly (Udara blackburni) caterpillars, one of two endemic Hawaiian butterflies, as well as the strikingly gem-like koa bug (Coleotichus blackburniae). [8]
The seeds were a food source for the Hopue or Greater koa-finch (Rhodacanthus palmeri). This beautiful bright orange and green honeycreeper was a native of the koa forests of the Kona and Kaʻū districts of Hawaiʻi Island, but is now extinct. [12]
ʻAʻaliʻi is one of the few native Hawaiian plants that can endure fires and a pioneer, or returning, plant over burned areas. [8]
Early Hawaiian Use
Fruits (capsules) and leaves were used in lei making by early Hawaiians. [1,4,9]
The seeds were boiled to make red dye for decorating kapa (tapa) cloth. [1,10]
The crushed leaves were used as a topical medicine for relief from irritating rashes and contageous diseases such as ringworm or "haole rot" and staff infections [2,5,8,10] Like hops, flowers were used to impart a bitter flavor, and also used as a tonic. [13]
The very hard, durable wood is heavy and sinks in water and so was used for bait sticks. From a canoe, the bait sticks were lowered into water at a depth or twenty or so feet to attract fish or heʻe (octopus), which then could be lured to the surface and caught with a waiting net. ʻAʻaliʻi was also fashioned into light fishing spears, especially for heʻe. [1,8,13]
The yellowish-brown wood, sometimes with black heartwood, was used for canoe building, weapons, agricultural tools, rafters, posts and thatching posts or purlins in house (hale) construction. [1,8,10,11,13]
An ancient boast of the people of Kaʻū states: "He ʻaʻaliʻi au; ʻaʻohe makani e hina ai" which means "I am an "ʻaʻaliʻi shrub; no wind can push me over," or in other words, "I can hold my own even in the face of difficulties." [2,3,9]
Modern Use
Capsules and leaves are still used in lei making as they were with early Hawaiians. [4,9]
Used in modern times throughout the world as a poultice or decocted for topical use only. This plant is mildly toxic containing small amounts of cyanogenic toxins and plant materials can cause cyanide poisoning if ingested. [8]
Aʻaliʻi wood is repotedly termite resistant. [8]
Use Outside of Hawaiʻi:
The wood has been used for tool handles, walking sticks, and carving inplements. The wood is also good for firewood as it ignites easily. [14]
