Anyone who wants to cultivate dandelions (taraxacum officinale) should have understanding neighbours. Beautiful flower it may be, invasive it is certainly, look at the seed head and imagine that lot blowing into your neighbours garden, and it has a tap root that means a taraxacum is for life not just for Christmas.

Plus the wild variety have bitter leaves, as opposed to the cultivated variety. So all that said, pass the Glyphosate.
