I wanted to compare the two, since I always suspected that they might not be the same.
Today I had them side by side. The leaf patterns are close but the fruit is totally different.
The St Anthony when ripe turns yellow while the Marseilles retain its green color.
The is no doubt in my mind that this Sicilian St. Anthony is the clear winner of the two.
Yes it is sweeter, softer, more moist and has more honey flavor that someone might look for in a honey type fig. It is more prolific. It puts out one only crop and is an early to mid ripening fig.
IMO, the original source is much more important than the common name of the varieties.

The inside tell the whole story. 100% different. Outside also different not to mention the eye color. Nice post.

Source of your St Anthony??

It originated from Scicily and was called St Anthony when I got it.

Could you clarify which is which in the photos?  Is the Marseilles on the left?  That one looks a lot like a honey fig I have which isn't supposed to be Marseilles and the identity is a bit suspect.

In All photos the Marseilles (Edible Landscaping) is on left and the Scicilian St Anthony is on right.

Thanks for showing these 2 figs side by side.
Although I still don't see a difference between Marseilles white and lattarula.   Anyone know how the lattarula fig got its name? 

I agree that Marseilles and Lattarula are the same. Don't know why the name Lattarula.

Today I snapped a picture of my Lattarula and Marseilles. I saw no difference, but the Marseilles this year has been ripening its figs faster. The Lattarula as of today had no brebas and no ripe fruit.
This is the first year I see fruit on my Lattarula.
The fact that they have two different names, could have something to do with the location from which they originated. Apparently the Lattarula is widely cultivated in southern Italy, and Marseilles is its local name in France.

The one on the left is Marseilles (I've been picking its fruit) and the one on the right is Lattarula.

Marseilles (EL) is in fact St. Anthony. At least by the one we know as to be similar to:

Ross, just because one nursery thinks a fig is the same they can be completely wrong . Lemon is not the same as white Marseilles. I grew them side by side for year until I discarded Lemon. Go to Petals from the Past website. I drove all the way from Charlotte to Jameison Al years ago and talked to them about these 2.
