This account is for my mother (the 62 in the profile) who is an avid gardener (though her health problems mean I have to do a lot of the “heavy lifting” for her). :-|

Living in Canada limits her options somewhat, but she nevertheless grows a plethora of flowers (including 6' tall lilies of numerous colors), vegetables (our record was a harvest of about 15 different kinds), and herbs (again our record is about 10 different kinds).

My favorite documentary on plants (and indeed on anything) is the incredible BBC mini-series How to Grow a Planet.
