Salvia species in southern California exhibit a variety of leaf trichome densiIes. S. mellifera, S. leucophylla, and S. apiana were chosen as study organisms because they exhibit varying trichome densiIes. A UniSpec was used to measure NDVI in leaves and an Instron was used to measure stem mechanical strength. This study provides preliminary evidence that suggests plants with high leaf trichome density have less stem mechanical strength, and those with low leaf trichome density have greater mechanical strength. Data generated from this study supports the idea that this may be a general and loose trend amongst plant families similar to Lamiaceae.
