I've never grown it.

The site which may not be named, in their database, says 6-8'. (That's one of their size categories.) There are no comments.

The French site Ventmarin likes to list height, but they don't know Michael Pollan at all.

Brad Gates own site doesn't give any useful info:

Aha! Local Harvest's page -- using Brad's description -- adds height information of 4-6'.

Whether any of this is what you'll see with your seeds, in your container, is anyone's guess.

alexshrugged, I grow Michael Pollan. It is an indeterminate, green/yellow, small plum tomato that gives big clusters of fruit with terrific flavor (IMO).

Good luck with your garden!

Bah! Thanks to you both! Looks like I'll need to scrounge up a bigger pot. Slowly but surely, my collection of tomatoes threatens to take over my whole deck....

Glad to know it will taste good, and be worth the extra effort!!

Definitely not a determinate!

Indeterminate ALL the way. Prolific.

Interesting. I live in a hot inland area, transplanted a plant I bought at a nursery. Not prolific and very resistant to ripening. Literally take weeks to ripen, even in this hot August we are having. Anyone with experience have any tips? They are tasty once they ripen but I planted this plant on May 25 and have gotten maybe 4 tomatoes. There are probably another 8 on the plant now that have been there for weeks and will not turn yellow; just light green and dark green.
