Angels’ trumpet flowering after 3 years

In the summer of 2016 I bought a Datura plant (Angel’s Trumpet) from Lidl supermarket for the princely sum of £1:49. It was the just a seedling and less than 4 inches in height. For the last 2 winters I have coddled it and did my best to protect it from the frosts and have reported it each spring into larger containers. This autumn my efforts have been rewarded with some magnificent 9 inch long flowers.
