One tree which I thought I recognised was Pinus montezumae, a statuesque conifer from the mountains of Mexico with drooping needles 18 to 25 centimetres long and forming a domed shaped medium sized tree. However, when I read the plaque by the tree, the name was Pinus devoniana. Apparently it had been labelled montezumae until a tree expert informed the arboretum that it was in fact the related species devoniana. Coming also from mountainous regions in Nayarit province this beautiful tree has long drooping needles up to 42 centimetres long.(16 inches).
It was a glorious sight with its emerging cones borne at the tips of the terminal growths and it should certainly be hardy in this country. It would be interesting to know if anyone grows it in Devon.
However, I can't find any reference as to what devoniana refers to - it certainly isn't the county of Devon! Could it be the Devonian period many millions of years ago, as conifers are one of the oldest families?
As it is, it is the most glorious tree and worth a space in any large garden.
