Herbicide trials involving thin line basal application of a chemical such as Garlon 4 in a diesel carrier have been suggested for the control of the tree.

Journal of the Torrey Botanical Society, 2: In its native range it grows in dry, moist, and wet forests on many soil types. Bocconia frutescens parrot-weed; plume poppy; tree celandine ; invading dry forest, with a native tree Pleomele auwahiensis in left foreground. In addition, the timing of the peak fruiting period provides a conspicuous food resource for birds in the area, especially during the beginning of the hot and dry summer months when other food resources become increasingly scarce Chimera, ; Chimera and Drake, Liogier and Martorell, ; Missouri Botanical Garden, Although Nishida and Johnson reported 38 natural enemy species within its natural range of Costa Rica, they advised that there may be serious constraints with the utility of these organisms and recommend that the search for other biological control agents be expanded to incorporate a broader range of its natural distribution.

Johnnson and Nishida found B.

Report on Bocconia frutescens. Combined with the ever-maturing population of reproductive sized individuals, the current B.

Critically endangered Hawaii Competition – monopolizing resources; Competition – shading Medeiros et al. Magnoliophyta — Flowering plants. Fosberg and Sachet still believed that it was possible to eradicate the weed at the time. The fruit is a capsule about 1. A 15 year analysis of vegetation changes in the same restoration site found that despite control efforts on reproductively mature trees within and in the vicinity of the exclosure, Bocconia seedlings were recruiting at significantly greater numbers than at the start of the restoration project, and were one of the six most common seedlings recorded in the bocclnia Medeiros et al.

Bocconia frutescens

Plant and Soil, 82 2: The plant is thick and bushy, producing multiple stems at times and spreading densely to produce “carpets” that shade out smaller plants. The anthers dangle from the flower center by their filaments. In an exclosure managed by the USGS-Biological Resources Division, the primary means of control involves the initial removal of all fruiting trees and the sporadic removal of the seed bank recruits.

Reproductive Biology The small apetalous flowers are not very showy, yet are frequently visited by non-native syrphid flies and honeybees Apis mellifera within the introduced range on Maui, Hawaii. It is known from cloud forests and several types of disturbed and degraded habitat.

This relative of the poppy is a shrub growing up to 6 metres frutescenw. Zone 9 is characterised by mild winters, long growing seasons and almost no winter freezes.


This method would probably only be practical for smaller diameter trees with single trunks.

Symbols for Unknown Plants. Notes on Taxonomy and Nomenclature Top of page The Papaveraceae, or Poppy family, comprises about 25 genera and species, which occur predominantly in temperate and tropical regions of the Northern Hemisphere Wagner et al.

Don’t need the entire report? Only a small fraction of plant families produce colored latex, so that was a good clue. Hawaii’s high-profile invasive species. Could poor seed dispersal contribute to predation by introduced rodents in a Hawaiian dry forest? It is worthy of note that the tree sampled for the fruiting estimate 4 m is approximately half as tall as the largest recorded individuals Bailey and Bailey, You seldom see more than an individual plant growing here and there.

Generate a print friendly version containing only the sections you need. Chimera and Drake, ; Johnson and Nishida, State agriculture or natural resource departments. The small apetalous flowers are not very showy, yet are frequently visited by non-native syrphid flies and honeybees Apis mellifera within the introduced range on Maui, Hawaii. This plant is capable of thriving in many types of habitat. Grows in full sun or moderate shade and can be irrigated regularly or given little or no supplemental watering in coastal gardens.

Once established within an area, however, the persistence of the seeds in the soil could allow for inadvertent dispersal through movement of contaminated soil from within the invaded area Veldman et al.
