1. What Are Rock Roses Succulents and Why Grow Them?
Rock roses succulents, scientifically known as Helianthemum, are low-growing, sun-loving plants ideal for rock gardens. Their vibrant flowers and drought tolerance make them a perfect choice for adding color and texture to your landscape.
1.1 The Appeal of Rock Roses
Rock roses offer a myriad of benefits for gardeners:
- Drought Tolerance: They thrive in dry conditions, making them perfect for xeriscaping.
- Vibrant Colors: Available in shades of pink, red, orange, and yellow, they add a splash of color to any garden.
- Low Maintenance: Once established, they require minimal care.
