Here's my report.
USDA Zone 9
Sunset Zone 16/17
Northern California - San Francisco Bay Area - North Oakland
[No ripe tomatoes yet. A late start - early to mid July with most plants
- I swear I won't be this late next year!]
At my house:
In a pot on the fire escape, about 7 hours daily of full sun, with some breeze:
SunSugar: Setting fruit, nice big trusses of fruit on the way, one tomato
on the first truss is big and green and I'm looking forward to tasting it
in a week or two. This plant is wind-whipped but gets lot of sun and is
blooming and setting fruit vigorously.
Next to it, in a five-gallon pot:
Two Ha-Ogen melon seedlings, also enjoying the sun, hope I can get a melon
or two from these late-started plants.
In the south-facing side yard, about 4 1/2 hours daily of full sun (and
light from the neighbor's porch light at night) and sheltered from the
wind. Most of the nursery plants and a couple of the volunteers have been
put in 33-inch cages, but I'm sure they will soon be outgrown:
Mystery Volunteer Tomato #1: Setting fruit, this looks like it will be a
plum-type or grape-type tomato. Should be ready end of August. This
volunteer has a sister plant (with the same potato-leaf growth pattern)
and I've rescued it from the shade where it was growing and moved it to a
better spot in the garden. No blooms yet on the second one.
Park's Beefy Boy (large red slicer), planted 7/13, from the nursery. Big
plant, blooming but no fruit set yet.
Early Girl, planted 7/13, from the nursery: Just beginning to bloom.
Monstrous plant with HUGE leaves, yellow-green in color (but soil is rich;
there is no nitrogen deficiency, plants nearby are deeper green). I
wonder if this is really an Early Girl or if there was a tag swap.
Mystery Office Tomato #1 (from a seed I found in my desk at work).
Planted 6/30, now has five true leaves and is working on a sixth; all
other things being equal it should have a flower truss after the sixth
leaf comes out in a week or so.
SunSugar, planted 7/13, from the nursery. Tall and spindly, several
flower trusses, several beady little green fruit. Disappointing when
compared with the robust SunSugar on the fire escape in full sun.
Mystery Volunteer Tomato #2 (again, a refugee from someone's kitchen
window). Rescued from the shade and put in a better spot in the garden.
Coming along fine. No blooms yet.
At the office, on the patio, full sun almost all day:
Mortgage Lifter: Huge plant, blooming, dropping blossoms, no fruit yet.
Sweet 100: Small green tomatoes and more on the way.
"Stupice" (no potato-leaf growth pattern, must have been a tag switch at
the nursery, Amish Paste was nearby, could this be it?): Vigorous,
setting many little fruits that have a plum shape. Should be ready end of
Pink Ping Pong: Big plant, slow to bloom and set fruit, just beginning to
set fruit, I think.
Sharing the 7-gallon pot with the Mortgage Lifter:
Crane melon (Sonoma County heirloom): big healthy vine, first female
blossom showing, should bloom any day now.
Sugar Baby watermelon: two healthy seedlings, should begin to run in a
couple of weeks, hope these can make it in that crowded pot.
 I think the large-fruited tomatoes are slower to set fruit in cool
weather/climates because their characteristically (larger) blossom doesn't
open fully enough for the pistil to extend past the stamens and the
stamens to open fully with their pollen load. This doesn't seem to be as
much of a problem with the blossoms of smaller-fruited tomatoes; all of
the flower parts seem to open quickly and at the same time, so pollination
is more effective.
