Hi,

I have inherited a few rhubarb plants on my allotment. I don't know
what variety they are; are there many different types of rhubarb?

Yes, quite a few.

What should I do with it? I think I heard them saying on radio4 that
it spread like I weed. Did I hear correctly? Will I have to keep my
eye on it?

No, it doesn't spread. You don't need to worry about that.
