Culture of Lavender (Lavandula ‘Regal Splendour’)


Lavenders, including the ‘Regal Splendour’ variety, are renowned for their drought tolerance once established. However, during their initial establishment period, it’s important to ensure that they receive adequate moisture. After planting, water the lavender deeply and then allow the soil to dry out before watering again. Overly wet or waterlogged conditions can lead to root rot and other issues, so it’s crucial to maintain well-draining soil and avoid waterlogged conditions.


One of the defining characteristics of lavender is its love for sunlight. Lavandula ‘Regal Splendour’ thrives in full sun, requiring at least 6-8 hours of direct sunlight per day to flourish and produce an abundance of aromatic blooms. When selecting a planting location, be sure to choose a spot that receives ample sunlight to ensure the plant’s vitality and prolific flowering.


Lavenders, including Lavandula ‘Regal Splendour’, thrive in well-draining, slightly alkaline soil. Sandy or loamy soils are ideal, as they prevent water from stagnating around the roots. If your soil is heavy or tends to retain moisture, consider amending it with sand, perlite, or gravel to improve drainage. Additionally, maintaining a slightly alkaline soil pH in the range of 6.7 to 7.3 is beneficial for the overall health and vigor of the lavender plant.

Uses of Lavender (Lavandula ‘Regal Splendour’)


Lavender is a versatile herb that imparts a delightful floral flavor to a wide array of culinary creations. The flowers of Lavandula ‘Regal Splendour’ can be used to infuse syrups, sugars, and teas, adding a unique and delightful aroma and taste to beverages and desserts. Additionally, lavender is a popular ingredient in herbes de Provence, a classic French herb blend, and is often used to flavor baked goods and savory dishes.


Lavender has a long history of medicinal use and is renowned for its calming and soothing properties. The essential oil derived from Lavandula ‘Regal Splendour’ and other lavender varieties is used in aromatherapy to promote relaxation, relieve stress, and improve sleep quality. Additionally, lavender essential oil is known for its antiseptic and anti-inflammatory properties, making it a valuable addition to natural first aid kits and skincare formulations.


The fragrant blooms and foliage of Lavandula ‘Regal Splendour’ make it a prized ornamental plant for its aromatic qualities. The sweet, floral scent of lavender is captivating and has been used for centuries in perfumery, potpourri, and sachets. Simply brushing against the foliage or flowers releases a burst of delightful fragrance, making lavender an excellent choice for sensory gardens and outdoor relaxation areas.


Beyond its practical uses, Lavandula ‘Regal Splendour’ serves as a stunning ornamental plant, adding beauty and charm to gardens, landscapes, and containers. The vibrant purple flowers and silvery-green foliage create an enchanting display, attracting pollinators such as bees and butterflies. Whether planted en masse, as a border, or in containers, this lavender cultivar adds a touch of elegance to any setting.


Lavandula ‘Regal Splendour’ is a relatively low-maintenance plant when it comes to fertilization. In fertile soils, it may not require additional fertilization. However, if the soil is poor or the plant’s growth appears stunted, a light application of balanced fertilizer in the spring can help promote healthy growth and abundant flowering. It’s essential to avoid over-fertilizing lavender, as excessive nutrients can lead to lush foliage at the expense of flower production and may negatively impact the plant’s overall hardiness.

To avoid the risk of over-fertilization, consider using a fertilizer with a lower nitrogen content, as nitrogen promotes vegetative growth at the expense of flowers. Alternatively, organic fertilizers such as compost or well-aged manure can provide a gentle, slow-release source of nutrients for Lavandula ‘Regal Splendour’, supporting its growth and flowering without the risk of nutrient imbalance.

Pruning and Deadheading

Regular pruning and deadheading are essential tasks for maintaining the health and appearance of Lavandula ‘Regal Splendour’. Pruning helps to encourage bushy growth, prolong the plant’s lifespan, and stimulate the production of new flowering stems. In late spring or early summer, after the first flush of blooms has faded, prune the spent flower spikes back to a point just above the foliage. This not only promotes a tidy appearance but also encourages the development of new flowering shoots, extending the plant’s bloom period.

In addition to regular pruning, deadheading—removing spent flowers as they fade—helps to redirect the plant’s energy into producing new blooms, rather than setting seeds. This practice prolongs the blooming period and ensures that the plant maintains a tidy and attractive appearance throughout the growing season.


Lavandula ‘Regal Splendour’ can be propagated through several methods, including cuttings, division, and seed sowing. Propagating lavender from cuttings is a popular and reliable technique that allows for the precise replication of desirable cultivars, such as ‘Regal Splendour’. Here’s a basic overview of each propagation method:

  • Cuttings: Propagate lavender from semi-ripe cuttings taken from the current season’s growth. Select healthy, non-flowering shoots and take 4-6 inch cuttings, removing the lower leaves to expose the nodes. Dip the cut ends in rooting hormone and plant them in a well-draining rooting medium. Keep the medium moist and provide bottom heat for optimal rooting.

  • Division: Lavender can also be propagated by division, though this method is more commonly used for rejuvenating older, overgrown plants. Divide the plant in early spring or fall, ensuring that each division has a healthy root system and several shoots. Replant each division in well-draining soil and provide appropriate care as it establishes itself.

  • Seed Sowing: While Lavandula ‘Regal Splendour’ can be grown from seed, this method is less commonly used for propagating named cultivars, as it can result in genetic variability. However, if you choose to grow lavender from seed, sow the seeds in a well-draining, sterile growing medium and provide warmth and bright, indirect light for germination. Transplant the seedlings to individual pots once they have developed several sets of true leaves.

Container Gardening with Lavandula ‘Regal Splendour’

Lavenders, including Lavandula ‘Regal Splendour’, are well-suited for container gardening, making them a versatile choice for those with limited garden space or for those looking to adorn patios, balconies, and other outdoor living areas with their charm and fragrance. When growing Lavandula ‘Regal Splendour’ in containers, consider the following tips for success:

  • Container Selection: Choose a container that provides ample room for the lavender plant’s roots to spread. Select a pot that is at least 12-16 inches in diameter and has adequate drainage holes to prevent waterlogging.

  • Potting Mix: Use a well-draining potting mix, such as a blend of peat moss, perlite, and coarse sand, to ensure sufficient aeration and drainage. Avoid heavy, moisture-retentive soils, as they can lead to root rot and other issues.

  • Watering: Container-grown lavenders may require more frequent watering than those planted in the ground, as pots can dry out more quickly. Monitor the soil moisture closely, watering when the top inch of the soil feels dry to the touch, and adjust the frequency based on environmental conditions.

  • Sunlight: Position the container in a location that receives full sun for the majority of the day, ensuring that the lavender plant has access to at least 6-8 hours of direct sunlight to thrive and flower abundantly.

  • Overwintering: In regions with cold winters, lavenders in containers may benefit from protection during the winter months. Consider moving the containers to a sheltered location, such as a garage or greenhouse, to shield them from harsh winter conditions.
