The name San Pietro is associated with at least 2 varieties of figs (not surprising, St Peter is popular in Italy). There is a green San Pietro that is similar to Dalmatie or Stella. I am writing about the purple San Pietro that is sold by Joe Morle of Italian Fig Trees. I received a cutting directly from another grower's tree during a visit in the fall of 2013. I labled it immediately, and received only 2 other cuttings from him at the time (Carini, which died in the rooting process and does not look like this, and Black Triana, which also looks different). I got the first fig last fall, late in the season, but the interior did not appear right. It had an amber colored interior instead of red. I posted pictures of it last season on F4F:

 The discussion at the time indicated that the fig should have had a red interior, like the fig pics posted later in that thread by the person who gave me the cutting.

There are only a few other F4F posts with info about San Pietro (JM):

 And a list of Italian figs that includes a purple San Pietro, which seems similar to the one sold by Joe Morle of Italian Fig Trees:

 And there is some discussion in an above post about California Brown Turkey being the San Pietro(JM) which seems erroneous, CBT is also called San Piero (spelled differently).

A link to Italian Fig Trees, the source of my friend's plant: http://www.figtrees.net/ No interior fig pics on the website. My leaves look similar to the ones on the plant photo but most leaf lobes not quite as deeply cut as those on the photo with the leaves and figs.

This year, I was impressed by the beauty of the developing figs of this plant.  I am growing it in a 5g SIP.

 

 

 



I know other figs can have similar striped colors as developing but this is the first for me.
The exterior of the ripe figs is a dark red/purple color. The first 3 figs of this plant this season have also had the lighter color interior, like last year.

 
 



 On the following 2 photos only the two figs on the right are San Pietro.

 
 

Sorry for the quality of the pics, working on my iPhone photography skillz.

The figs are very sweet, but not quite the complex flavor like the several Mt Etna types, Malta Black, VdB or Red Sicilian(MN) that I have grown this year, but have more flavor than the light exterior / light interior figs like Lattarulla and Atreano.

So, why is this fig's interior light color? I have gone over the list of other cuttings I started later that year, and found no others that should have looked like this (there were a couple of unknowns, however). I have tried to be extremely careful with cutting labeling, pot labeling, and record keeping, and I feel sure that I did not mix this up with another cutting or plant (anything is possible though). Not sure what to think of this, the difference should not be environmental, the person I got it from lives less than an hour's drive away in the same zone. Could this be some kind of mutation? Immature plant? Mixed up grower?

Input welcome!

Thanks for looking.

Well, I can't tell you why the interior is light and not dark, but the pictures look great and the fig looks so delicious and juicy!

You put a lot of information in this thread.  I hope someone has an answer for you.

Have you tried contacting the person from whom you got the cuttings?  Maybe he can shed light?

Here is mine from last year!  It's a great tasting fig!

Hi eboone,
Nice fig, but you need more to be sure of the type of fruit (color, size,...).
I had figs growing 30 minutes away and that would already make a huge difference, like figs ripening or not, like getting brebas or not.
On your tree, the bark is dark. Check if the tree of your source has the same dark color. The bark color remains the same. Some are grey, some dark but dark is less common.
Could you post some leaves too ?
For the stripes you need to compare at least 5 fruits from the same tree.
On my trees, I often get odd ripening figs. I have one tree that makes violet, yellow or green or violet and green fruits and some with such stripes and with or without ribs.
It all depends on the weather, direct sun on the fruit, heat and humidity at the time of the ripening.
For the light color of the pulp, here, during this summer long hot spell and with poor watering, my "dalmatie" were ripening like that instead of redish ...

Dennis - thanks for your post.  Do your San Pietro figs have the striping while ripening like in my photos?  And yours are uniformly red/pink centers?

jdsfrance - all of these have shown that progressive striped effect as they ripen. 
And I will try to get some leaf photos added but my schedule will be pretty crazy until after the Labor Day weekend. 
The light color noted on this variety was at end Sept last year, in cooler weather.  Here it has been pretty warm while ripening the past 2 weeks.

Is it dropping figs??

No not dropping figs at all.  They have been delicious!  Just trying to figure out why mine has an amber/yellow looking center for me and the few other posts about it show a red center.

I had a similar situation with a white fig I was growing. Last year the inside was more on the brown side. This year is deep red color. It's a seven year old tree. Never knew what happened. Give it another year just to be sure.

This is pretty typical of the larger leaves, while the smaller ones from early in the season are mainly 3 lobes or 'duck foot' in appearance - there is one of those partly visible to the left and below the white background in this picture.
