In 2013, the first flowering Magnolia campbellii was recorded on 19th February, a full month before the official start of spring in England.
In 2014 this date was a little later on the 3rd March. This brings us to the question, when will spring arrive this year?
The Great Gardens of Cornwall will be monitoring seven Champion Magnolia campbellii trees to see exactly when they bloom. When all seven trees have at least 50 blooms spring will have arrived in Cornwall.
