Historical record
United States trademark registration 925,734 records KRIMSON PRINCESS for live plants, registered to B.L. Cobia Inc. on 21 December 1971. The certificate records an application filed on 20 May 1970 and a claimed first use of 31 October 1969 (original PDF p. 1).
The record documents a commercial designation and its historical registration. It does not establish botanical parentage, make the trademark a botanical name, authenticate a present-day clone or demonstrate current trademark status. The historical association with Rubra is discussed separately in the 2025 Cobia nursery history.
