Yeah I don't think those hollow fruits are particularly worthwhile. Our native viridescens is like that, with a hole at the base to release the seeds. The edible ones I had today (latispinus) are fleshy and soft and sour but not very sweet. I still haven't yet mastered ripeness, because if you wait too long the pulp just starts drying up. The fruit is actually the reason I got histrix, and the reason I have 3 of them.
Regardless of those details, those red flowers are incredibly intense, and the buds and fruits provide sharp contrast. Such a lovely plant as that would last about three days here by the sidewalk, before it sprouted legs and walked away in the night.
