Special Notes and Information
Kuluʻī belong to the Amaranth family (Amaranthaceae). Other native Hawaiian family members include five species of Charpentiera, a rare and little known amaranth (Amaranthus brownii) from Nīhoa, ʻāweoweo (Chenopodium oahuense), and three species of Achyranthes.
The name Nototrichium comes from the Latin nota, remarkable and tricho, hair, probably referring to the dense pubescence of the plants.
Early Hawaiian Use:
Apparently the flowers and wood of kuluʻī were packed into a hallow stem such as bamboo (ʻohe), lit on fire and thrown from a particular cliff. The firey material would eject much is an aerial display much like modern-day fireworks. [1] Pāpala kepau (Pisonia spp.) were also used in a similar manner. (See Plant Profiles for Pisonia)
Landscape Use:
Kuluī is beautiful as a single free forming, in clusters, or as a trimmed hedge. The downy floral displays are one of the nicest features of this shrub but the silvery foiliage will first catch the attention in the landscape. An excellent xeric or drought tolerant plant, use kuluī in a well drained sunny area. Very nice as a accent shrub with other native xeric trees and shrubs such as koaiʻa, wiliwili, naio, nāʻu, ʻaʻaliʻi,ʻūlei, ʻohe makai, lonomea (āulu) and mānele to name a few.
Kuluī may be grown as container plants in full sun with regular watering. [2]
