Although they look similar and I vaguely recalled the name, I am now wondering whether these are in fact what I have grown. Lots of senior moments these days! Mine are Asiatic lilies. have grown quite tall, have large trumpet flowers and are perfumed. However, there is nothing answering the description "tree lily" in the plant encyclopaedia and RHS certainly don't recognise the term. T & M are almost certainly using poetic licence for marketing purposes and it is bad practice on their part not to use latin names and variety names. They are probably Asiatic hybrids imported from Holland that grow particularly tall and develop a shrubby appearance over time.
