I posted over on the binaries.pictures.gardens but no response so far... thought I'd try here too...
I bought this in 1972 as a tiny 89 cent pot plant and I have never seen another one just like it... I think it is some kind of asparagus but not any that I can identify.
I have never seen any flower or fruit on it - however 'insignificant'. I have tried to divide it and nearly killed it.
It has appreciable thorns.
TIA, Sterling
