Hi Littlecheryl, and welcome to ATP!
I don't recall any of the descriptions specifying "for high altitudes". Maybe short-season tomatoes? If your friend knows some names of varieties that do well at high altitudes, I could look to see if I have those.
I found this PDF about tomatoes in Idaho:
http://www.cals.uidaho.edu/edc...
"YOU ARE A SHORT-SEASON, HIGH-ALTITUDE GARDENER IF:
You live in Idaho at an elevation above 4,500 feet,
OR
Your USDA hardiness zone is 4 or lower,
OR
You have a frost-free growing season of 110 days or less"
Scanning to see what they recondite:
"For a list of tomato varieties recommended for short-season, high-altitude areas, consult
“Choosing and Growing Adapted Vegetable Varieties” in the Short-Season, High-Altitude Gardening Series:
http://info.ag.uidaho.edu/pdf/...
But that link didn't work for me.
Try:
http://www.cals.uidaho.edu/edc...
That whole website might have gardening info specialized to idaho, but it might apply to parts of CO also.
They suggest these:
VARIETY - - - - DAYS TO Maturity - - - - - HARVEST NOTES
Better Bush 72 Large, red, bred for container planting
Champion 62 Large, red, good fruit set in cold climates
Early Goliath 60 Largest early variety, dark red fruit, good slicer
Fourth of July 49 Medium size, red, one of earliest varieties
Golden Girl 69 Small to medium size, gold color, high yield, sweet
Northern Exposure 67 Medium-large, red, compact, good in high
elevations
Phoebe’s 65 Large, red, bred in Rexburg, ID; hard to find
Roma 62 Small-medium, red, oval shape, good for sauce
Siletz 57 Medium size, dark red, seedless slicer, full flavor
SubArctic Maxi 48 Small-medium, red, recommended for high elevations
Sweet 100 65 Small, red, very prolific, sweet flavo
I think I once had a trade pkt of Siletz but can't find it. I might still have 'Sub-Arctic Plenty' but not 'Sub-Arctic Maxi'.
(But again, my single-pkt tomatoes from trades will be older seeds, like 2011-2013 and some older.)
