Argentea Picta (modern trade plant)
The newer silver-leaved plant sold as Argentea Picta, recorded separately from Cobia’s historical cultivar.
The modern trade plant is recorded separately from the historical cultivar. The shared label does not establish that all modern plants belong to one clone.
Overview
This page concerns the newer silver-leaved plant circulating as Argentea Picta, separate from the historical selection described in the 1973 patent. The shared name does not establish that they are the same plant, or that the historical cultivar has survived. The modern plant’s origin, selection history and relationship to other silver-leaved carnosa remain unresolved. Plants carrying this trade name also need separate propagation histories before they can be treated as one authenticated clone. The linked historical page contains Cobia’s patent description and photographs.

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 1973 patent belongs to the historical selection, whose description includes waxy streaks or patches, pale margins, persistent reddish young growth and frequently irregular flowers. Those historical characters and measurements must not be transferred to the newer trade plant as if it were the same cultivar (patent cols.1–6 / PDF pp.2–4).
- The cultivar registrar warns that material circulating under the name may differ. A selling name or a similar leaf colour cannot resolve that uncertainty. This page records the modern usage separately and does not authenticate every plant carrying it (registrar, Notes & other sources).
- Argentea Princess and SILVER PRINCESS are not automatically interchangeable with the modern Argentea Picta label. Their application needs source-specific origin and transfer records; a similar word or silver leaf pattern does not establish one clone.
What We Are Still Learning
Who selected the modern plant, and when did this exact material enter circulation?
What would help: Original selector or nursery records, dated labels and the earliest documented transfers.
Do modern plants sold as Argentea Picta represent one clone or several different plants?
What would help: Separate accession histories, flowering records and repeated comparisons of traceable plants.
How does this modern material compare with the historical plant and other silver-leaved carnosa?
What would help: Comparable photographs across leaf ages and flowers, measurements under recorded conditions, and original naming records.
Common Misconceptions
- This newer trade plant is separate here from the historical Argentea Picta; a shared name does not make them the same plant.
- The historical patent does not establish this modern plant’s origin, measurements, flower form or care needs.
- Modern use of the name does not demonstrate survival or rediscovery of the historical cultivar.
- Silver-looking leaves do not establish an authenticated cultivar, a biological mechanism or equivalence to Argentea Princess.
