Wow! Great resource! Thanks Greyphase! I know this was originally posted for the apple items, but anyone that is thinking about switchgrass should do a text search in the database for it. It looks to me like they will send you 200 seeds(about enough to seed 8-10 sq ft) of multiple varieties. This would be a great experiment for someone with a few square feet that they aren't using, especially if they are thinking about seeding switch on their place. Do your own free "switchgrass trial" to find out what grows best on your place(Higgins can suck it!). The varieties with the heaviest stems and greatest height would most likely be the ones that the guys in the northern areas would be looking for, provided it was an ecotype that would thrive in their area. It sucks that it takes multiple years to get it to full maturity, but I think it would be beneficial and fun if a guy had the extra room.
In looking at the accessions list, I came up with the ones I would try, based on traits that would be best for long-standing cover:
Largest stem diameter: BN-14669-92 - 6mm, OZ-70 - 5mm, OTO - 5mm, T 4237 - 5mm, PMT-785 - 5mm, many with 4mm stems.
Tallest foliage height: PMT-785 - 14dm, BN-14669-92 - 13dm, OZ-70 - 10dm, T 4237 - 8dm, OTO - 7dm, many between 11dm and 7dm but with smaller stem diameters that may not hold up to deep snows, ice, and high winds.
Overall plant height: OZ-70 - 23dm, T 4237 -20dm, PMT-785 - 19dm, BN-14669-92 - 18dm, again many others in between with smaller stems.
If I were to set up this trial, I would use 6 - 3' x3' square areas spaced 3' apart. You would need a 9' x 15' total area.
Put one of each of the following varieties in each area:
OZ-70
BN-14669-92(from Mississippi, may not work well in northern areas) Alternately use Kanlow
OTO
T 4237
PMT-785(from FL most likely will not thrive in the north) Alternately use WS8U
and finally one "control square" with good old CIR switch for comparison purposes.
Any bets one of these types could be the "little known public variety" that Higgins tries so hard to keep secret. Maybe one of these could be even better in certain areas? Damnitall, I need a piece of dirt to tinker on!
