Rheum

looks good enough to eat

LOL better not try though eh!:)

Are they poisonous Grindle same as Ruhbarb

Very healthy looking!

Bj from what I can find the leaves are the same, not sure about the stems, I'm not convinced I want to try either LOL

Does this one get very big?

not too sure AA ;this is its second year and it's 2ftx2ft, I'll look and see if the label is still there
