Most often from too much shade, excess nitrogen, or impatience — young plants can take 2-3 years to bloom. Site in full sun and avoid rich feeding.
Invasive suckering
Underground runners pop up across beds and lawn; install a root barrier or grow in a contained bed and remove suckers promptly.
Structural damage
Aerial rootlets cling tightly and can damage mortar, gutters and paintwork; keep it off house walls and onto dedicated frames.
Skin irritation
Handling sap or foliage can cause itching and rash in sensitive people; always wear gloves and long sleeves when pruning.
