I'm indebted to Gordon and Mieko Hay who alerted me to the presence of this magnificent Pasqueflower on the chalky slopes of Denbigh's Hillside. Whether it is here down to human hand or wind-blown seed, I do not know. However it got here it is more than welcome as far as I'm concerned. I have seen a single, lonely plant on chalk downland before, at Martin Down on the Wiltshire/Hampshire border. That is considered to be native. As for this Surrey specimen? Wiser men and women than me will have an opinion.
