Wilbur Graves
A historically described carnosa selection with broad leaves and irregular pale markings.
The historical Wilbur Graves description and the importance of propagation history are kept separate from look-alike plants and added trade labels.
Overview
Wilbur Graves was described in a 2006 issue of P. S. The Hoyan, where Christine M. Burton listed it among carnosa cultivars. She described broad leaves with irregular white areas, often covering half or more of a leaf. This establishes a published description by 2006; it does not establish when the cultivar was first named. The original selector, naming publication and date remain unresolved in the reviewed records.

Evidence-Based Growing Insights
No form-specific care conclusion has passed review. The parent Hoya page remains the source for shared information; generic advice is not repeated here.
What We Know
- The historical description compares its broad leaves with the motoskei type. This is Burton’s descriptive comparison, rather than a new taxonomic determination or proof that every modern plant with a similar leaf belongs to this selection.
- Burton’s description documents substantial irregular white markings, but it supplies no leaf measurements, diagnostic flower description or propagation history. It does not establish a required percentage of pale tissue on every leaf or explain the markings’ anatomical mechanism.
- In a 2022 interview, National Collection holder Felix Horne explains that Wilbur Graves should descend from one particular carnosa plant. His emphasis is on a documented propagation connection. The interview does not identify that original plant’s selector or authenticate a particular modern accession.
- Silver markings alone are insufficient to connect an unidentified carnosa to the historical selection. Labels with added words such as China, Russia or Silver should be preserved exactly; their equivalence to the historical plant has not been established here. A geographic word on a received label does not by itself document a wild collection locality.
- The reviewed sources do not establish distinctive flowers, a controlled comparison of marking stability, or a Wilbur Graves-specific growing requirement. Historical leaf descriptions and collection advice should not be turned into promises about every plant carrying the name.
What We Are Still Learning
When was Wilbur Graves first named as a cultivar?
What would help: An original dated naming publication or earlier description, with its author, issue or catalog imprint and the complete relevant passage. The 2006 description is a documented occurrence, not a verified first naming date.
Who selected the original plant, and whom does the name commemorate?
What would help: Contemporary correspondence, nursery records or a published origin account explicitly connecting the person, plant and name.
Which living plants have a documented connection to the historical selection?
What would help: Original labels and dated propagation or acquisition records, retaining added label words and recording any missing links.
What do traceable plants show over time?
What would help: Repeated leaf and flower photographs of the same documented plant and its cuttings, with leaf age and growing conditions. Include creator credit and permission for photographs the Library may display.
Common Misconceptions
- A description published in 2006 does not establish that the plant was first named in 2006.
- A silver-marked carnosa cannot be assigned the name Wilbur Graves from appearance alone.
- Added words such as China, Russia and Silver do not establish synonymy, cultivar identity or a wild origin.
- The historical description does not require every leaf to be at least half white.
- An unsuccessful online register search does not prove that no earlier naming publication exists.
