Digging around, it looks like hazeman made his headband (or pollenated his 45 day pe x hb mom with the hb bx pollen) in late 2010, with beans going up for sale in 2011.
I can't find the exact post atm, but when i was looking for info on these a month ago before ordering, i found a post by him saying Loompa gave him the bx pollen.
Here's his description:
When hazeman posted up a pic of his pe x hb mom used in the cross, the first thing i noticed was- just the outside of the leaf fingers turn purple, and has what appear to be purple trichs.
And looking thru the pics of lhb, i noticed some of the pics feature the same purple edges on some of the leaf fingers.
Is that a lhb trait?
