Anthuriums (A. andreanum) are perennial herbaceous plants with creeping, climbing stems, prominently veined leaves, and usually grown in areas with semitemperate climate like Baguio [Philippines]. Its attractive features can be compared to roses, orchids, and chrysanthemums. The production of this plant has been increased due to popular demand of consumers. Traditional varieties are still grown in the lowlands but the production and quality is not as good as the new varieties that are successfully grown in cooler climates. Thus, the author evaluated and screened new anthurium varieties for adoptability in the lowlands. Methodology presented were: ten anthurium varieties of uniform age and size were observed for two years: Pink a Dee Dee, RCM 12, Anue-nue, Nitta (check variety; locally grown cultivar), Sunburst, Kaumana, Kansaku, De Weese, Baguio White, and BSU Red. These plants were planted in 10 inches clay pots filled up to three-fourths of the pots with layers of coconut husk, charcoal, and dried carabao manure as potting media for anchorage, aeration, and source of nutrient and moisture for maximum growth and development. Anthurium plants were laid out in raised rice hull bed with three layers of black net as shading material. One-half teaspoon complete fertilizer (14-14-14) per plant supplemented with foliar fertilizer at the rate of 1 teaspoon Albatross (18-18-18) per gallon (3.8 L) water was applied once a month to all varieties. Crop protection management practices were employed as needed. Agronomic parameters such as leaf area, canopy spread, number of flowers harvested per plant, spathe area, length of spadix, length of petiole, number of suckers produced per plant, and vaselife of the flowers were gathered for two years. It was found out then, that the following varieties were recommended: Anue-nue for larger canopy spread, spathe, and leaf area; De Weese and Kansaku for longer length of petiole and spadix; De Weese for more suckers; and pink a Dee Dee for more flowers. De Weese had the annual highest net income of P67.53/plant and an 87% return per peso invested. On the other hand, Nitta had the lowest net income of P7.59/plant and ROI [return-on-investment] of 10%
