I posted over on the 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 a baby tree of some kind...?? About 10" tall - shot with a piece of white paper behind to increase detail. Looks like some kind of pine or fir??
