Bleeding heart plant
The photo shows a part of my bleeding heart plant, at least it's attached to the plant and is growing out of the plant but it looks like a weed to me. What is it? Is it part of the bleeding heart plant? It's getting taller than my tree and seems to be suffocating the bleeding hearts.
I'm sorry we did not receive your photo.
If the leaf structure if different then the main plant, you certainly could have a weed or even a tree self seeded growing out.
You could carefully cut away the invasive plant material.
