Title: Re: [NAFEX] olive trees found in Bulgaria at -4'F
I'm halfway suspicious that it might be Russian Olive (Eleagnus), but I can't tell enough from the picture.  Hector Black?  You can probably tell.
   Even if it is an olive, that doesn't mean it will bear.  I had an uncle who had a peach tree in Iowa where peaches shouldn't grow, but this one did.  But it never bore because the fruit buds are more tender than the leaf buds and they froze every year.  The result was a beautiful vigorous, non-bearing peach tree.  Might be the same with the olive - it would grow, but the flower buds might be frozen out.
   As to the fig, I have a Desert King that has survived 0 F without freezing off.  The trick is to grow it in a dry location to force it to harden off well.

Subject: [NAFEX] olive trees found in Bulgaria at -4'F

The link above is by a person in Bulgaria that has found olive trees growing
at a local agricultural university.  There are two picures given.  One is a
fig tree that died in a previous extremely cold winter.  The other is of an
olive that survived under the same conditions.  The olive tree appears to be
thriving, from the photo.  Recent temperature in Bulgaria is near 0'F.  I
did some research recently that indicated that the hardiest olive trees
could only survive down to about 10'F.  This is proof that there are a few
olive trees that are even hardier than that.  No mention was made of the
fruit it produces, if it happens at all.  I hope this guy can propogate it
and start sharing it with others.

Postings at this message board are not archived, and in a couple of weeks it
will be gone.  I have made a copy of it for my own reference at
