ABOUT
Lavandula angustifolia 'Imperial Gem', commonly known as English lavender, is a perennial plant famed for its beauty and fragrance. This particular cultivar has a compact and bushy growth habit, forming a rounded and dense shape that is made up of numerous slender, upright stems. The leaves of English lavender are narrow, long, and typically a striking silver-green color, which serve as a lovely contrast to the vibrant flowers. The flowers themselves are what make 'Imperial Gem' a standout. They are a deep, rich violet-blue hue, and they bloom profusely in tight, terminal spikes atop slender, yet sturdy, flower stalks. These vivid blossoms are highly prized for their intense color and potent fragrance, which carries the quintessential lavender scent: a soothing, herbal aroma that is both sweet and slightly floral. Blooming typically occurs in late spring to early summer, and when in full flower, the plant boasts a profusion of these colorful spikes, creating a striking visual display. Additionally, when the flowers are in bloom, English lavender becomes a magnet for bees, butterflies, and other pollinators, adding to the dynamic appeal of the plant in a garden setting. The overall appearance of English lavender 'Imperial Gem' exudes a sense of classic elegance and is often used in formal garden designs, as borders, in herb gardens, or as a low hedge due to its tidy and neat form. Aside from its ornamental uses, the flowers can be dried and used in sachets, potpourris, and for essential oils, making it a versatile plant for both aesthetic and practical purposes.

WaterThe English Lavender, specifically the 'Imperial Gem', should be watered deeply yet infrequently, as it prefers well-drained soil and does not tolerate being waterlogged. Aim to water when the top inch of soil feels dry, which could be approximately once every 1 to 2 weeks, depending on the climate and weather conditions. Typically, you'll want to provide about 1 gallon of water per plant each time you water, ensuring it's applied directly to the base and avoiding getting water on the foliage. During hotter, drier periods, watering frequency may increase slightly, but always check the soil moisture beforehand. It’s crucial not to overwater, as English Lavender is drought-tolerant and susceptible to root rot in wet conditions.
LightEnglish Lavender thrives in full sunlight, needing at least 6 to 8 hours of direct sun daily to perform best. Place it in a spot where it can receive unfiltered, direct sunlight through the majority of the day. Avoid areas that are shaded, as too little light can lead to poor flowering and a leggy growth habit.
TemperatureEnglish Lavender prefers a temperate range and thrives best when daytime temperatures are between 60 and 70 degrees Fahrenheit. It is quite hardy and can survive minimal temperatures close to freezing; however, it's best not to subject it to prolonged periods below 20 degrees Fahrenheit. Ideally, protecting the plant from extreme cold or frost will help ensure its longevity and health.
PruningPrune English Lavender once a year in early spring or after flowering to maintain its shape and encourage robust, bushy growth. Pruning involves cutting back by about a third of the plant's height, avoiding cutting into the woody base. For the 'Imperial Gem' variety, also remove any dead or spent flowers during and after the blooming season to promote further flowering and prevent the plant from using its energy to set seeds.
CleaningAs needed
SoilThe best soil mix for Lavender (Lavandula angustifolia 'Imperial Gem') is a well-draining blend consisting of coarse sand, peat, and compost or aged manure in equal parts to promote aeration and avoid water logging. The ideal pH for Lavender is slightly alkaline, ranging from 6.5 to 7.5.
RepottingLavender (Lavandula angustifolia 'Imperial Gem') does not need frequent repotting; it can be repotted every 2-3 years or when the plant has outgrown its current container. Repotting is best done in the spring just before new growth begins.
Humidity & MistingLavender (Lavandula angustifolia 'Imperial Gem') prefers low to moderate humidity levels. It thrives in dry conditions, which closely mimic its native Mediterranean environment, making it ideal for arid and semi-arid climates.

Life cycleLavandula angustifolia 'Imperial Gem', commonly known as English lavender, begins its life cycle as a seed, which, when sown in spring or autumn, germinates in warm, well-drained soil. Upon germination, the seedling begins to develop, forming a compact shrub with narrow, aromatic leaves. In the first year, vegetative growth is prioritized, with the plant establishing a strong root system. From the second year onward, the lavender enters its flowering stage in early to mid-summer, producing vibrant purple flowers that are highly attractive to bees and other pollinators. After flowering, seeds can be collected, and the plant can be pruned to encourage bushy growth and prevent woodiness. English lavender typically has a lifespan of about 10 to 15 years, during which time it will annually go through these growth and reproduction stages, with winter dormancy in colder climates.
PropogationPropogation time
Spring-Early Summer
Propogation: The most popular method of propagating Lavender, specifically the Lavandula angustifolia 'Imperial Gem', is through softwood cuttings. This is best done in late spring, when new growth is supple and has not yet matured to hardwood. You should take a cutting about 2 to 4 inches long, ensuring it has a couple of leaf nodes. Strip the leaves from the bottom half of the cutting and dip the cut end into a rooting hormone for better chances of success. Then, plant the cutting into a mix of potting soil and perlite or sand to provide adequate drainage. Finally, keep the soil moist but not waterlogged and cover the plant with a plastic bag to create a greenhouse effect, which helps to lock in moisture and warmth aiding in root development. In a few weeks, when roots have developed, the lavender can be transferred to a larger pot or into the garden.
