Abstract

Spider plant (Cleome gynandra) is a very important source of livelihoods and food for the majority of households in Kenya. Consumers show preference to spider plant compared to other African leafy vegetables due to its nutritional value and health benefits. This study sought to elicit implicit prices and preference levels for spider plant attributes. A cross-sectional survey research was used to obtain data from 100 consumers with the aid of semi-structured questionnaires. Hedonic pricing model in STATA 11.0 was fitted to estimate the influence of attributes on observed prices. Results indicated that leaf size and leaf colour significantly influenced the price paid by consumers to spider plants at P<0.01 and P<0.05 respectively. Consumers paid premium price for green colour leaves and discounted purple colour leaves. Based on the findings of this study, it is recommended that spider plant breeding activities should focus on broad leaves and green leaf colour as the main attributes positively influencing consumption utility and farmer income.
