Mrs. Theodosia B. Shepherd Descriptive Catalog of California Flow
I've just completed the latest archive of the historic Theodosia Shepherd Descriptive Catalog of California Flowers. Mrs. Shepherd grew her roses and many other types of plants at her nursery in "Ventura by the Sea" in the late Eighteenth and early Nineteenth Centuries.
Ventura wasn't that large of a city 115 years ago, but there was great wealth from oil and other natural resources. She offered 85 roses in 1898, 80 of which are uploaded and referenced on HMF at the link below. Five are documented in the Comments section as they aren't easily matched to any roses we have information about.
Mrs. Shepherd is considered the founder of the California seed and cut flower industry. Quite an achievement for a woman business person over a century ago. Kim
