Using California Invasive Plants of Spring to make Inks and Pigments

Using California Invasive Plants of Spring to make Inks and Pigments

April 29, 2023
Explore the use of California invasive plants as art materials for inks, watercolor, and environmental restoration.

Join Elissa Callen in Point Reyes National Seashore to explore the use of California invasive plants as art materials for inks, watercolor, and environmental restoration.

Throughout the course, students will learn about native and invasive plants, how to ethically harvest plants as color for dyes, inks, and pigment, and how to process them into inks and watercolor.

Students will also gain a better understanding of the importance of building a deeper relationship with the natural environment through learning about conservation and the ecological impact of their artistic practice. This class will be specific to the California invasive plants that can be found in the Spring.

Elissa Callen is an artist and horticulturist with a background in painting and fine gardening/landscape design. Her creative practice focuses on environmentalism and sustainability through the use of locally collected and hand crafted plant-based inks and natural pigments.
