Tim has been collecting and growing ornamental gingers since he was a young teenager. His main interest then, and still is, in the gingers but he is very interested in ornamental bananas as well. Given a big enough greenhouse or a tropical environment, he'd grow all of the Zingiberales. Tim operates a mailorder nursery, Gingerwood Nursery. He is actively collecting and breeding new gingers. In 1994, Tim wrote the first version of his book Ornamental Gingers: A guide to cultivation and selection, followed by the second edition a year later. Currently, he is working on a reference site for Gingers and bananas, as well as an on-line forum to help bring collectors together and to educate the public.
