William Rennie (horticulturist)

William Rennie (1835-1910) was a Canadian farmer who became a successful seed merchant, educator, and writer on agriculture.

Rennie started farming his own 120 acre section (Concession II Lot 14 in then Markham Township and now eastside of Bayview Avenue south of 16th Avenue of Richmond Hill)[3] in 1860.

But in 1867 he rented out his farm, moved to Toronto, and opened a seed company that sold both vegetable and floral seeds.

Most of his customers purchased their seeds through a colorful mail order catalogue.
