Heather Elizabeth Apple (born 1948) is a Canadian writer, artist, and educator, with an interest in organic horticulture.

In late 1987, after the HSP had lain dormant for about two years, Heather Apple, as a long-term organic gardener, past president of the Durham, Ontario chapter of COG, and a Seed Savers Exchange contributor, responded to a request from Alex Caron and volunteered to reinitiate the programme.

[3] Her aim was to develop it as a grass-roots seed-saving organization modeled after the Seed Savers Exchange,[4] and beginning with an announcement in August 1988, she produced a separate newsletter for the program[3] which became a magazine by December 1988.

[5] The Heritage Seed Program/Semences du patrimoine grew to become Seeds of Diversity Canada/Semences du patrimoine (SoDC), incorporated and renamed in 1995; Apple served as president of SoDC thru 1993.

She also served as vice president of the Society of Ontario Nut Growers (SONG), 1990–1991.
