The response of blood-lily, scadoxus multiflorus ssp katherinae, to daylength, shade, and other production variables

Joseph F. Garofalo, Wagner A. Vendrame

Abstract


Geophyte production in Miami-Dade nurseries, in USDA Plant Hardiness Zones 10 and 11, is limited mainly to tropical and subtropical species, including Crinum, Hippeastrum, Hymenocallis, Agapanthus, several "elephant-ears," and a few others. Several studies were initiated in 1995, in Fort Lauderdale and Homestead, to determine the production potential of blood-lily, Scadoxus multiflorus spp katherinae, as a bloomingpot-plant crop for South Florida nurseries. Because this species has been little studied, limited information is available. Studies were conducted to determine the effects of the percentage of shade and length of the daily light/dark period on production and timing of the crop. The potential for early and late forcing were also investigated.
