Picture of the Day: Laburnum Arch, Unknown, UK 
When I was a child in the UK, laburnums seemed to be everywhere. Trees in domestic and ornamental public gardens would bloom a vibrant yellow every year. The annual display looked lovely and would add further enjoyment of the garden to gardeners and visitors.
Then, sometime in the mid-nineties, around about the same time as the campaign to identify all lone males as potential child sex pests began, a paranoid parent announced to the world that laburnum was poisonous and could kill little children. So began the terrible genocide and eradication of the laburnum in the UK and the lovely trees were cut down to make way for hot tubs, decking and patios - because having weird back garden sex parties in full view of the neighbours, drowning your sacrificial victim and burying them under the patio or decking is a much better alternative than having to tell little Johnny not to put the poisonous seed pods in their gobs. You wouldn't want to hinder a child's self expression would you?
Years passed and with the thinning of the laburnum they became an almost unfamiliar sight in the UK to such an extent that when I saw one on my travels growing over a lovely pergola I forgot to enable my phone's GPS and the location of the said laburnum has been lost to time and memory.
They are lovely though.
