fuldraw - the cuttings were a mix of left overs. Hybrid willow & poplar, shrubs, and specialty willows. Probably about 30 or 40 different kinds mixed in there. If nothing else we'll know which ones do best!
sandbur - RC and I are old enemy's. I have hybrid willows that are in their 4th growing season planted in the middle of a nasty RC stand. They are finally about 12' tall. They should be more like 30' tall. And the RC killed more than 1/2 of them. I can't recommend planting in RC, but I'll continue to experiment (think Oust XP).
Thanks,
