Description Wollastonia integrifolia is a slightly woody perennial plant with spreading stems up to 6 1/2 feet long. The stems grow outward from the center intertwining with the stems of neighboring plants, often rooting where they touch the soil, to form a mat 6 to 8 inches thick. The oval green leaves are small and succulent. The leaves range in length from 1/3 to 1 1/4 inches long, but only a fraction as wide. The 1/2 inch wide yellow flowers are daisy-like and grow on stems above the foliage. The flowers can be single or in groups of two or three. Wollastonia integrifolia flowers throughout the year. (Koob 1999; Wagner 1990) |

Habitat and Geographic Range Wollastonia integrifolia is endemic to Hawai'i. It is found along the coastal areas of all of the main Hawaiian islands and on Kure Atoll and Laysan. (Wagner 1990) |

Propagation by Seeds The seeds of Wollastonia integrifolia are tiny, generally less than 1/8 inch long. Wollastonia integrifolia can be grown from seeds. (Koob 1999; Wagner 1990) |

Propagation by Cuttings Wollastonia integrifolia is most easily grown from cuttings. Koob recommends planting tip cuttings in a moist, well-drained, sterile medium such as perlite or sharp sand. Rooting hormones, mist beds, and humidity chambers are not necessary. Boche reports 90% success in rooting stem or tip cuttings unde 50% shade using a medium of 3 parts peat moss to 1 part vermiculite. Rooting will take place in 2 to 4 weeks. (Boche 1992; Koob 1999) |

|
Propagation by Division Wollastonia integrifolia plants can be divided. Because the stems often root at the nodes, sections of established planting beds can be removed with a sharp shovel or knife and replanted. Do not over water these divisions. (Koob 1999) |
