Hattie the Hen
Deeply Rooted
Hi SaltyMomma,
They are easy to grow from seed if you can't get a plant near you. Just give it enough room when you plant it out as it will eventually produce off-sets all round the original plant. It is a magnificent architectural plant in the garden. Mine grows to about 10>12ft tall but HiDelights seem to be even taller.
As to the taste, it is much nearer to that of artichokes than celery (you will be glad to hear ).
Good luck with finding one or growing your own from seed.
