testing plant edibility
It is similar to dandelion, but not exactly like the pictures I am seeing. How can I safely test it?
Is this a plant that you grew? Or is this a plant that you found?
Where was is growing? Are there flowers? How large is the plant?
Has the area of harvest been sprayed with any chemicals?
There are many questions that would need to be answered.
From just the leaf that you have sent us I cannot identify this with any certainty, therefore do not consume any plants that have not been identified.
