well, the silks coming out the end were brown (a bit beyond that actually)
anyway, pulled one off and unwrapped it - took a wee while
half of it looked like sweetcorn, but the half towards the tip was under developed.
overall - wouldn't say it was an edible specimen!! there are several more though where th esilks are still white, so i'll keep an eye on them and hopefully they'll come good.
thanks
