Other than the description that it grows up to 5 feet tall and has red stalks, I haven't been able to find a source for "Mammoth Red" rhubarb plants anywhere.
I'm wondering if it has essentially gone extinct? After going over several search engines for an hour and a half, I couldn't find anything more than perhaps a dozen descriptions of the plant, mostly in variety lists.
Can anyone please help me find a source for these plants? I would really like to plant a row of them along my fence. Help!!!
