Greetings iiamNkanyamba and others,
As you suspect, the plant in your photos is not indeed a dandelion, Taraxacum officinale, although it is in the same (huge) family, the sunflower family (Asteraceae). When you find a dandelion, all the leaf bases and all the flower stems ALL originate from the central point that marks the top of the underground taproot. Dandelions also exude milky sap wherever they are injured. The plant in your photo has many branches (dandelions never have branches because of the structure described above) and I believe is one of the flowers in the genus Senecio; in fact I believe it is Senecio jacobaea, tansy ragwort.
This particular Senecio is quite toxic for all mammals, including us bipeds. This is the 'arm' of the sunflower family that produces pyrrolizidine alkaloids. These compounds are acutely toxic to the liver in large doses-causing hepatic venous occlusive disease. In tiny doses over time they change one risk for liver cancer--and NOT in a good way. They are responsible for significant livestock losses in your nation.
But, as you seek dandelions, the further you get into spring, the more likely you are to see some dandelions. Finding them early helps because they are at their sweetest right after they appear, then become bitter depending upon their exposure to sunshine.
I hope this helps you on your quest--they make excellent salad greens and the flowers make great fritters when fried in pancake batter.
Thanks for reading.
