- 🌱 Anthurium andraeanum 'Princess Alexia' is a hybrid cultivar developed through selective breeding for its exceptionally deep burgundy coloring and heart-shaped form, making it more dramatic than wild-type species.
- 🌱 Under ideal conditions, mature plants can produce 2-3 new blooms per year for 5+ years, making them among the longest-blooming houseplants available with proper care.
