I purchased two tomato plants last spring that were simply marked
"Dufresne". No one has been able to tell me much about them except that
they are listed as "endangered" and that they are a Quebec heirloom. There
is almost no information about them on the web and there are contradictory
statements about them there (some pages say red, some say pink, for
example). They have recently set fruit in Canada Zone 5a, which I believe
is 3a US.

Can anyone tell me the basics of this heirloom variety? Colour? Days to
maturity? Size? Taste?

I know there is also a "Dufresne #2". I know nothing about this one,
either.

The only possible source I have found for Dufresne is through "Seeds of
Diversity Canada".
