Q.What Are The Tiny Flower-like Growths At Top Of Plant?
My bleeding heart is in its 3rd summer of never blooming. 1st summer it threw up a tall spike, no flowers, but tiny flower-like growths which turned white before dying off. All this in early fall. This year, plant came back late spring & has grown about 3′ tall. It now has tiny flower-like growth that are white & look like a tiny bell seed pod.

They are probably flowers, or primordia that will grow into a flower. Your photo did not come through, so I cannot confirm.
