I went back to my NAFEX files and retrieved this discussion I'd saved, from 
March 2000 - it might be in the archives somewhere.


>From: <ramoyer@king.edu> (Richard A. Moyer)

>Several points:
>1)  For Donna and Dan who are in Tenn and Fla, respectively:
>Lucky is right that 'Jennybelle' is perhaps best adapted to warmer 
>climes.  I have obtained plants from J.S. AKin in LA and Hidden Springs 
>Nursery.  This is a tree form and not a bush, though I presume it would 
>respond to pruning.  Hector with Hidden Springs says 'Regent' may be their 
>best cultivar.  I prefer the latter, my wife the former.
>
>2)  RUST:  I asked specifically about rust on Juneberries at Southern 
>Fruit Fellowship meeting last July.  No one in the group has seen it in 
>their plantings in the southeast.  Perhaps this is one of the few diseases 
>we escape.  There is a planting of over a hundred AMelanchiers (many 
>cultivars) at the Mountain Crops Horticultural Station in Fletcher, NC, 
>near Asheville.  Viewed these in fruit several years ago and no trace of 
>rust on fruit or plants.  Rust on Amelanchier, regardless of source, is 
>not an issue for us in the southeast, Zone 6-9 as best I can determine.
>We have significant cedar apple rust pressure.  I do not spray for it, 
>have cedars all around with galls, and have Spigold apple which develops 
>CAR each year to varying degrees.  My amelanchiers 15 feet away have no 
>discernable sign of rust on fruit or leaves.
>When out in Corvallis NCGR several years ago was amazed at the extent of 
>rust damage on the Amelanchiers there; some of  the same cultivars I have 
>here without rust.
>Don't know about multiple strains of CAR, or if it's quince rust, etc. I 
>DO get significant rust on Mayhaws here, so much so that I am topworking 
>the tree.
>
>Lon, Have seen dozens of native Amelanchiers at multiple locations in 
>southern appalachians from 1500 to over 5000'.  No rust observed on ripe 
>fruit on these, but so far the fruit size and flavor of the cultivars we 
>are growing are superior to native fruit we have tasted, so cultivars are 
>recommended here.  (Native Juneberries at 5000' are ripe in early 
>August.  (Augustberries, anyone?)
>
>It is my impression that Ken Asmus does not have significant rust pressure 
>at his Oikos Nursery site either.  have a call into him to check.
>
>To echo Lon, if Amelanchier cultivars don't work for you, look for natives 
>for the stuff is all over N. America.  But keep in mind that Juneberries 
>cultivars do perform well for many in certain parts of the country.  Try 
>your site and see!  In our experience they may need to be coddled to get 
>them going, but after that they are great freeze beaters.

>This is something I keep harping on.  Most of the commercially available
>Juneberries are selections from other climates - particularly Canada - and
>are not suited to local environments in many places.  But Amelanchier is so
>widespread that it ought to be possible to select local cultivars almost
>everywhere.  I have a local selection of A. alnifolia that gets less than 5%
>rust when the Canadian selections are totally wiped out (all fruit infected)
>with rust.  I'm sure there are even better selections to be had.  Instead of
>buying cultivars, NAFEXers need to go out and FIND local selections - they
>grow in fence rows, around larger trees, anyplace the birds drop them.
>Propagation could even be by seed, for a while.  Then you own't have the
>problems you have with the commercial ones.
