From the Supplement (Vol. V)
The tree in the Villa Taranto gardens on Lake Maggiore now flowers fairly regularly. Planted in 1937, it is many-stemmed and about 60 ft high. Probably deficient summer heat is the cause of its not flowering in Britain.
The examples at Caerhays, Cornwall, now measure 59 × 3[3/4] ft and 56 × 3[1/2] ft (1984).
