Asteraceae Week Part 1-Radiate Heads: Arctotheca prostrata from California-GS22 : Attachments (3). 2 posts by 2 authors.
While going through my California plants, I found some I had missed earlier.
Leaves are close to Gerbera.
My best guess is Arctotis arctotoides which is in cultivation in the USA (see calflora). It is also similar to Gerbera and Gazania and I am not 100% confident of my identification.
Your guess seems to be correct as per the link below since the flowers and leaves are both matching.
Pl. also consider Arctotheca prostrata as per images and details herein.
To me appears close.
… suggestion of Arctotis arctotoides looks closer to me.
Did you check the link I had sent?
Yes, I checked it. Looked a bit different.
Not the first image, the subsequent ones.
Arctotis and Arctotheca are quite similar. The paper by McKenzie et al. 2011 (sciencedirect) is quite useful for distinguishing features:
Table 1. Comparison of selected morphological characters in Arctotis sect. Anomalae with other sections of Arctotis and Arctotheca.
However, I ‘m not convinced I could see any of these with confidence in the photos so I am not 100% sure. Both are possible.
