Sam,
I'm in TN, just a bit NW of Nashville. I suspect
that 'Crandall' is not one clone, but lots of selfed seedlings sold as
'Crandall' over the years by various nurseries, which is why you see so many
different descriptions. The one I have is from Raintree Nursery, and is
definitely only partially self-fertile. When I hand-pollinated it with some
pollen from flowers on some other cuttings I was rooting, the fruits were 3-4
times larger than those from selfed flowers. Maybe next winter I should
request cuttings from others with different 'Crandall's, and see how they
compare side by side.

Hal,
where are you located? My experience here in Minnesota is that Crandall
always sets as much fruit as it can handle. My one bush is isolated and
has been fully self fertile.
Also, I'm pretty sure they no longer exist, but Prof. N.E. Hansen at
South Dakota State University selected a number of golden currants (and
possibly some clove currants) with better-than-average horticultural
characteristics. These were given Indian names. Dr. Hansen's long
dead and I doubt whether the S.D. Agricultural Experiment Station has
maintained that germplasm. I donated a report on his selections of
cold-hardy fruits to the NAFEX library. -- Sam Brungardt, St. Paul,
Minn.
Richard,
Yes, I'm evaluating quite a few clove and
golden currants. This will be the first year for any of them to fruit other
than 'Crandall', so I can't make any fruit comparisons yet. These are a
mixture of seedlings, both wild collected and some 'Crandall' crosses, along
with some named and un-named selections from the Corvallis repository. They
all handled last summer's intense heat and drought really well, were little
affected by the Easter freeze, and most have had no sign of disease. They
have a highly variable range of bud break, bloom and resistance of the
flowers to late frosts. 'Crandall' has the latest bud break and bloom of
all, but a couple of others overlapped well enough that 'Crandall' has set a
huge crop this spring. In the past, the fruit set was lower and the fruit
small without cross-pollination.
One seedling has a very odd habit. This is from
'Crandall' x 'Gwens'. I sent some seedlings to my father in Arkansas, and
this one quickly spread over a large area, and began blooming early, and
never stops blooming spring through fall. Even the suckers, that pop up
several feet away, start blooming almost immediately. The fruit drop off
when small, so it probably needs cross-pollination. I'll be getting some
suckers from it soon, so I can see how it does here.

Rob,
Our currant that defoliates least in the summer heat is
'Crandall'. This is not a European Black Currant (Ribes nigrum),
but a selection of American native (Ribes odoratum).
Native through much of rockies, also down to N. Texas.
So should be able to handle your heat but still would appreciate
afternoon shade. Currant breeder Stan Pluta evaluated many black
currants at the NCGR repository in Corvallis, OR, and he and Kim
Hummer published an article in Fruit Varieties Journal
entitled "Surprise, it's Crandall". You can get a
copy through interlibrary loan.
Hidden Springs Nursery and Edible Landscaping have both
offered 'Crandall' in the past. Both have SE US humidity, so
should be a good testing ground for Red Currants you might want to try as
well.
If you search this list archives, much more info on 'Crandall'
there.
Hal Love is working with currants in TN, if I remember right, so
he's worth asking as well. As are Adam and Sue Turtle.
