Those with pollen allergies might experience sneezing or itchy eyes during its flowering season. To reduce exposure, avoid planting it near windows or areas where you spend a lot of time during its bloom.
Common problems
Overwatering can cause root rot. Poor drainage or heavy shade may lead to weak growth and fewer flowers. Occasionally, it may attract aphids or fungal diseases if air circulation is poor.
