Fun Facts
- 🌱 Moerloosei roses are part of the hybrid rose group and were developed to combine the vigor of wild roses with the ornamental qualities of garden roses.
- 🌱 The semi-double flower form (typically 8-20 petals) allows pollinators better access to the flower's center than fully double roses, making it an excellent choice for supporting bee populations.
- 🌱 This variety is known for its exceptional disease resistance, particularly to powdery mildew and black spot, making it a low-maintenance choice compared to many modern hybrid roses.
