One Green World sells a Lattarulla fig.  

Edbile Landscaping sells both White Marseilles and Lattarulla.

Arent White Marseilles and Lattarulla supposed to be the SAME variety?

Many sites identify the Lattarulla and Italian Honey as being the same fig.  EL says the Lattarulla is also called Danny's Delight and the Marseilles as the Oregon Prolific or St. Anthony fig.  Some plants end up with several common names. To complicate the problem, some growers slap their own name on an already established variety for their own marketing purposes. 

I grow hot peppers and we have similar problems.  With peppers, we are dealing with plants that are so easily cross-pollinated that hybrid seed is unknowiingly passed on as representing the parent variety.  Soon five gardens are growing the same pepper under five different names or five different hybrids under the same name but with marked differences in taste and appearance.  It becomes difficult for many of us to know what the original wild or landrace pepper we think we are growing should actually be like.

I'd bag a few mid-season flowers.  Most believe insects (and wind the a lesser degree) are the main means of natural cross-pollination.  Given the range of many insects, it seems a bit difficult to me to be assured of self-pollination within any reasonable distances.  I assume you are talking about growing in your yard, not a field full of the same strain.

If the seed you grew from this year is pure it matters not how those flowers are pollinated, the plants will all produce the same fruit.  Cross-pollination will not affect this season's crop, only the seed produced in this season's fruit.

I ordered both trees from Edible Landscaping this year. The Italian Honey/Lattarula came as a big tree (3-4 feet) with five branches and four large figs on it. Their Marseilles is probably not the Marseilles White but is described as having yellow figs and the tree they sent was about half the size of the IH. The leaves on both trees seem similar but the nursery stock is distinctly different. 

      Dennis sold me on Latturula when he said: “I love the bright yellow color of Latturula when they're ripe and its sweet honey flavor.  It's like eating a super soft cotton ball drenched in honey!  It just melts in your mouth…. If you don't have Latturula, then get one....You will be glad you did! “ http://figs4funforum.websitetoolbox.com/post/el-lattarulla-and-st-anthony-marseilles-5390618?highlight=super+soft+cotton+ball+drenched+honey&pid=1285625257#post1285625257

       I have no idea which “box of chocolate” Marseilles they sent. There was extensive discussion on the different Marseilles out there and which one was the one grown by Thomas Jefferson. This was one thread: http://figs4funforum.websitetoolbox.com/post/whiteyellow-marseilles-feedback-6874590?highlight=white+yellow+marseilles+synonyms&pid=1282593460#post1282593460  Edible Landscaping provided it to Monticello in the early 1980's when Monticello was redoing their historical gardens, making an attempt to replant varieties that likely existed on the estate during Jefferson's time. Michael in Virginia posted: “I'm slowly collecting all the Marseilles plants I run into if they are supposed to be separate varieties. I can tell you that the Marseilles that is grown at Monticello is a great tasting fig. It was in my top ten last year.”

This seemed to sum up the forum discussions: “the topic of the white Marseilles variety(s) generally ends with everyone agreeing to not to talk about Marseiiles anymore and just accept they have a fine fig :)”

I have a small Lattarula from the Luther Burbank Home and Gardens, in Santa Rosa. Ross, rusty_hooks, helped prune the old tree, and is distributing starts to people in the area. He says it is a fabulous fig.
