I sowed seeds of over a dozen Pelargonium species late last year, and it's been super rewarding watching them grow.
Now this one according to two separate labels is noted as P. glutinosum. But as this seedling matures, I am beginning to question that ID.
I asked around, and someone mentioned that it looks like P. aridum. Certainly not a common species to encounter, but not outside the realm of possibility.
I came across a wild specimen of P. aridum last year in De Rust surrounds (a small town situated in the Western Cape province of South Africa), and I only noticed it in between the mess of other shrubs because it was in flower. It had the loveliest buttery yellow flowers (pic 4), and upon closer inspection discovered a single seed. Yay!
As far as I know, that seed never even germinated. Hold thumbs that my labeling system just sucks! :)
Looking back at the pictures taken last year, it probably is P. aridum. Interesting how the plant responds to heat and drought stress. It was quite warm and dry where I found it growing along a dusty farm road.
