Carroll Abbott (1926-1984) was the founder of the Native Plant Society of Texas and one of the early promoters of preserving and gardening with native plants. You can read his biography on the state NPSOT website. This YouTube video shows an interview with Carroll Abbott discussing his motivation for preserving the Wildflowers of Texas. There is also a wonderful story on the NPSOT website – Remembering Carroll Abbott | Native Plant Society of Texas (npsot.org)
The Kerrville chapter of NPSOT has created a garden at Riverside Nature Center in Kerrville that is dedicated to Carroll Abbott. The garden is planted with Texas native plants, many of which were special favorites of Mr. Abbott. You can link to the early newsletters that Carroll Abbott put out prior to starting NPSOT.
