As a versatile plant, it attracts pollinators and is perfect for borders, herb gardens, and rock gardens, bringing beauty and utility with its fragrant presence. 

Lavandula ‘Superblue’ is named for its exceptionally rich blue-purple flowers, which are more intense than most other lavender varieties. The Superblue lavender is native to the Mediterranean region, particularly in the rocky, sun-drenched hillsides of southern Europe. Today lavender is growing worldwide, with ‘Superblue’ flourishing in USDA hardiness zones 5-9.

One of the standout features of Lavandula ‘Superblue’ is its compact, bushy growth habit, which typically grows up to 1 foot tall and spreads about 1 foot wide. Its leaves are grayish-green, narrow, and finely textured, adding a silvery accent to its deep purple blooms.

The plant’s dense foliage creates a lush mound, making it an ideal choice for edging pathways or filling smaller garden spaces. Superblue lavender retains its neat, tidy shape with minimal pruning, adding a controlled yet vibrant touch to any landscape. 

The flowers of Lavandula ‘Superblue’ blooms in early to mid-summer and produce tall spikes of fragrant, blue-violet flowers that are highly attractive to bees, butterflies, and other pollinators. The blooms rise gracefully above the foliage, creating a visually striking contrast with the silvery-green leaves. The flowers emit a classic lavender scent, and their rich color persists throughout the bloom cycle, adding a long-lasting splash of color to garden beds and containers. 

Its flowers can be harvested and dried for use in potpourris, or sachets, bringing their calming fragrance indoors. In gardens, the plant’s fragrance can help deter pests, and its flowers attract beneficial pollinators.  

Lavender is also popular essential oil that is used in herbal medicine and aromatherapy for its soothing, stress-relieving properties. Furthermore, it’s an ideal companion plant, blending well with other drought-tolerant species like sage, rosemary, and thyme. 

When and How to Water Superblue Lavander 

The Lavandula Superblue is a drought-tolerant plant that requires minimal watering once established. This means watering the plant thoroughly when the soil is dry to a depth of about 1-2 inches. It's essential to allow the soil to dry out between waterings to prevent root rot and other issues caused by overwatering.

In the spring and summer, during the growing season, you can water the Lavandula Superblue plant approximately once every 7-10 days, depending on the weather conditions and soil drainage. It's important to adjust the watering frequency based on factors like temperature, humidity, and rainfall. During hot and dry periods, you may need to water the plant more frequently, while in cooler or rainy weather, you can reduce the watering frequency. 

In the fall and winter months, you should reduce watering to allow the plant to enter a period of dormancy. Water the plant sparingly, only when the soil is dry to the touch, about every 2-3 weeks. This reduced watering schedule helps mimic the plant's natural growth cycle and prevents waterlogging during the plant's dormant phase.

By understanding the seasonal watering needs of the Lavander Superblue plant and adjusting your watering routine accordingly, you can help promote healthy growth and ensure the plant thrives in its environment. Remember to always monitor the soil moisture levels and adapt your watering schedule based on the plant's specific requirements to maintain its overall health and vigor. 

Light Requirements – Where to Place Your Superblue Lavender 

When grown indoors it’s essential to place your superblue lavender in a location where it can receive ample bright, indirect sunlight. A south-facing window is ideal for providing the plant with the necessary sunlight it needs for healthy growth.

If a south-facing window is not available, you can supplement the light with a grow light to ensure the lavender receives adequate light exposure.

For outdoor cultivation, Lavandula Superblue plants thrive in full sunlight. These plants require at least 6-8 hours of direct sunlight daily to flourish.

Choose a spot in your garden or landscape that receives plenty of sunlight throughout the day. In regions with hot summers, providing some afternoon shade can help protect the plant from intense heat and sunburn.

Indoor Lavandula SuperBlue plants may benefit from spending time outdoors during the warmer months. If you choose to move your lavender plant outdoors, gradually acclimate it to direct sunlight to prevent sunburn. Start by placing the plant in a partially shaded area and gradually increase the exposure to full sunlight over a few days.

Optimal Soil & Fertilizer Needs

The Superblue Lavender plants prefer well-draining soil with a slightly alkaline pH level 5.9 to 6.2. A sandy or loamy soil mix with good drainage is ideal for Lavandula Superblue. You can improve soil drainage by adding perlite or coarse sand to the soil mix to prevent waterlogging, which can lead to root rot. Planet Desert has specialized potting soil, opens in a new tab that includes an organic substrate with mycorrhizae to help with the growth of a healthy root system to help your plants to thrive. 

When it comes to fertilizing Lavandula Superblue, it's important not to over-fertilize as these plants are sensitive to excess nutrients. Fertilize the plant sparingly to avoid causing damage. A balanced, NPK fertilizer formulated for flowering plants can be applied in the spring as new growth begins. Alternatively, you can use a diluted liquid fertilizer once a year during the growing season to provide your superblue lavender with essential nutrients. 

By selecting the right soil mix, ensuring proper drainage, and providing appropriate fertilization, you can help your Lavandula Superblue plant thrive and produce healthy growth and vibrant blooms.
