Dear Rlalique and vngarden
I wish I had seen this before Rlalique, my favourite plant, in fact my first publication as new record from Kashmir in 1970 soon after my Masters degree. Interesting because this plant was was given to us in M. Sc. examination, till then not reported from Kashmir, and not even described in Flora of British India, from which we were supposed to identify the genus. Somehow I described the plant, but was very uncomfortable to identify it as Sonchus (a name which our teachers thought it was). So the first thing I did after joining research was to study this plant and publish as first record of Senecio vulgaris.
The plant is very common in Sunnyvale here, flowering these days profusely.
It is a common weed in the garden and woods. I was just out there to photograph fungi, my second favorite to photo after orchid. I already amassed around 940 genera of plants. I can't find anything else to photograph except for fungi or weeds.
It is good to hear that this S. vulgaris brings back your memory!
I'm quite jealous of the weather in Sunnyvale, CA. As of now and maybe to spring, it is not ideal to do photography in Seattle because it is kind of dark. I still use a point and shoot (canon sd1400) so it is not good in low light condition.
