At Traphouse Nursery, we are following two variegated Bidens alba lines recorded in our notes as Albo and Aurea.
What we observed
In our October 15 update, I reported three generations in Albo and two in Aurea. My approximate counts were around 10 variegated seedlings out of 50 in Albo and 20 out of 50 in Aurea.
These are preliminary nursery observations, not standardized, replicated trial results. They do not establish the cause of variegation, a simple inheritance ratio or lasting stability.
The next useful comparison
The useful next question is whether the difference persists when labeled cohorts are counted at comparable ages under documented conditions. Parent identity, sowing dates, germination, losses, growing conditions and changes as seedlings mature all need to remain visible.
The observations give us a question to investigate; the next records must show what actually happens.
Sources and context
Kew Plants of the World Online accepts the species name Bidens alba (L.) DC. Albo and Aurea are the working nursery labels used here; this account does not establish registered cultivar identities.
The UF/IFAS-hosted propagation resource on variegation explains that variegation can arise through several mechanisms. That background does not identify the mechanism in these nursery lines.
The numbers above were approximate observations reported in the October 15, 2026 update, rather than new counts collected for this article.
