Perennial small shrubs are typically long-lasting, with a lifespan of around 10 years. These plants emit a pleasant fragrance, and their blue flowers are not only elegant and pure in appearance but also highly ornamental. They are commonly used in herb gardens and are considered an excellent choice for garden cultivation. Even after the flowers have dried, they retain their aromatic qualities, making them perfect for use as sachets or potpourri.
These shrubs are easy to grow and thrive in well-drained, sandy soils that receive plenty of sunlight. They are heat-resistant, drought-tolerant, and can withstand poor soil conditions, as well as light salt exposure. They are extremely hardy and can survive temperatures as low as -10°C to -15°C. To maintain their shape and overall appearance, it's recommended to prune them in the spring. However, avoid pruning in the fall, as this may weaken the plant’s ability to withstand cold weather.
In colder regions, it's best to plant them in a greenhouse during the spring to protect them from harsh winter conditions. Before sowing seeds, you can treat them with a solution of 20-50 ppm erythromycin to promote healthy growth. Germination usually takes between 1 to 3 months at a temperature of 15°C. Once a good number of seedlings have emerged, carefully transplant the small seedlings into individual pots. Then, gradually acclimate them to outdoor conditions in late spring before planting them outside. This method ensures stronger, more resilient plants that will thrive in your garden.
