Requests cut flowers and potted chrysanthemum plants is increasing from year to year, in line with improving standards of living. This study aims to obtain best medium composition on the growth of two varieties of chrysanthemum. Research was conducted in greenhouses West Sumatera Institute Assessment and Agricultural Technology in Sukarami Solok, from August 2015 to January 2016. The study is based on completely randomized design factorial of two factors with three replications. The first factor is the chrysanthemum varieties consisting of two levels (Limeron and Merahayani) and the second factor is the composition of the media that consists of four levels (soil: sand: husk fuel: 1: 1: 1, soil: sand: chicken manure: 1: 1: 1, soil: sand: coconut fibers 1: 1: 1 and soil: sand: municipal waste compost: 1: 1: 1. The results showed that growth of Merahayani varieties better than Limeron varieties. The composition of medium affect the growth of chrysanthemum ornamental plant. The media composition soil: sand: municipal waste compost: 1: 1: 1 the best for the growth in the number of leaves, number of flowers, fresh weight and dry weight of plants. The composition of the soil media: sand: husk fuel: 1: 1: 1 the best for the growth of flower diameter and length of the longest root.
