Name that rootstock!

What’s this rootstock that Four Winds put my St Teresa lemon on?

Try calling Four Winds and ask them what they use as a rootstock for their Saint Teresa Lemon trees.

I'd say it looks like Citrus macrophylla, aka  Alemow or Colo.

Howdy.  I got an STF lemon from Four Winds a couple of years ago.  An employee I spoke with at the time said that it was on C-35, which was what they were using on all their trees except for a few mandarins.  As of then they were no longer using the Cuban shaddock which had been their primary rootstock for decades.  I was told that they had never used Flying Dragon.  Four Winds had never been particularly forthcoming with rootstock information in my experience. A super secret trade secret apparently.  It took at least half a dozen calls to find someone who was willing to talk about their rootstock(s). 

I'm keeping the STF lemon in a pot. I think it'd be too vigorous to join the rest of my citrus trees, all planted in ground on Flying Dragon.

That does look like macrophylla.

Thanks for the info loneroc1, and Lazz for the confirmation. Is the macrophyla very cold hardy? I’m guessing not.

I think Macrophylla cold tolerance  is about the same as similar things, i.e. rough lemon, citrons, volk, rangpur etc. I never noticed it to be overly cold sensitive.

I've only grown one years ago, it was a variegated macrophyla & not hardy at all. I lost it in a freeze.

Laaz, you certainly have found more variegated citrus varieties than anyone I ever known.  They just run over to you house.
