Joe:
    This is a well written piece on how our Hostas can change either in our
own gardens or in the labs. I have a Whirlwind, bought 3 years ago and only
3" tall, I think it's time to give up on that one but not to worry, I bought
another one last year and it is performing as it should. Thanks
Pat
