This tree is a culinary treasure and totally unique in any garden with its broad conical spines and graceful form.  In spring, white umbels of flowers are followed by dark pink fruits born in loose clusters. It is the pink pericarp is the tongue tingling spice used in culinary dishes and medicinally for its numbing effect.  Lovely pinnate leaves.  Aka Zanthoxylum bungeanum.

Though the species is gendered, its reproductive strategy is shared by a few plants (Acer griseum is perhaps one) where you have male and female plants, where the female plants are self fertile.  This makes sense as I’ve grown seedlings from previous harvest from this tree but have been unsuccessful finding this plant’s mate.
