As far as I know, he issues only one bulb catalogue. He was also issuing
a Narcissus one, but I don't know whether he still does.
Orders need to be in before August 1.
He has to restrict how many plants he lists. As he wrote in the 2004
catalogue, his bulb packing shed is set up for 530 items. In 2003, he
listed 682, and it was a "packing nightmare".
However, he grows well over 4000. It means that every year there
is something new to look forward to.
