The Rock Rose (Helianthemum nummularium) is an exceptional plant that will undoubtedly enhance any garden with its beauty. This perennial, evergreen shrub grows to a height of 20-30 cm and is known for its vigorous branching, forming low, dense mats. Its relatively large flowers come in a variety of colours, making them highly decorative. It is perfect for rock gardens, walls, and perennial borders, adding a unique charm.

Sowing

The Rock Rose is best sown under cover, allowing for better control over the growth conditions of young plants. It's essential to prepare the substrate properly, ensuring it is well-drained and permeable to provide optimal germination conditions.

Sowing Depth

The seeds should be placed at a depth of about 0.3 cm. This depth allows for quick and even germination while protecting the seeds from drying out and adverse weather conditions.

Sowing Period Under Cover

When should you sow Rock Rose seeds under cover? The best time for sowing is from March to May. This ensures the young plants have ample time to establish a strong root system before being transplanted to their permanent location.

The ideal planting period for the Rock Rose is from July to August. During this time, the plants will adapt and prepare for the upcoming winter while maintaining their evergreen form.

Plant Spacing

When planting Rock Rose, it's advisable to maintain a spacing of 30x30 cm. This distance allows the plants to develop freely and branch out, preventing overcrowding which could lead to fungal diseases.
