hyacinth 'Royal Navy'


The Hyacinth 'Royal Navy' is a strikingly beautiful plant known for its rich, deep blue flowers. Resembling a dense spike or column, the blooms are tightly packed with small, star-shaped flowers that cascade around the central stem. Each individual flower contributes to the overall cone-like shape of the flower head, creating a plush and luxurious appearance. The petals have a slightly wavy or curly edge, adding to the fullness of the blossom and giving it a textured look. The color of the 'Royal Navy' is particularly noteworthy—a deep, vibrant blue that sometimes appears almost navy in intensity, which is quite rare and highly sought after in the floral world. When in full bloom, the contrast between the blue flowers and the dark green, glossy, strap-like leaves is especially eye-catching. The leaves grow upright and provide a simple yet elegant backdrop to the showy spikes of flowers, highlighting their magnificence. Furthermore, the flowers emit a strong, sweet, and pleasant fragrance which can fill the surrounding area and attract passersby or wildlife like bees. The overall impression of the Hyacinth 'Royal Navy' is one of opulence and splendor, making it a beloved choice for gardeners who wish to add a splash of luxurious color and irresistible aroma to their early spring gardens.

  • water dropWater

    For the Hyacinth 'Royal Navy', water thoroughly when the top inch of soil feels dry, which is typically once every 5-7 days depending on environmental conditions. Provide enough water to moisten the soil all the way through, but avoid waterlogging as this can lead to bulb rot. During active growth, in spring, you may need to water more frequently, while after blooming, reduce watering as the foliage begins to die back. In terms of the amount, use approximately half a gallon of water per plant during each watering session, making sure the water penetrates the soil evenly around the bulb. Adjust the amount based on the size of the pot or garden area, to ensure adequate moisture reaches the roots.

  • sunLight

    The Hyacinth 'Royal Navy' thrives in full sun to partial shade. The ideal spot would be where the plant receives at least six hours of direct sunlight daily. If planted indoors, a south-facing window is generally the best location, while outdoors, an area that gets morning sun and afternoon shade can also be beneficial to protect the blooms from intense afternoon heat.

  • thermometerTemperature

    Hyacinth 'Royal Navy' prefers moderate temperatures ranging from 60 to 70 degrees Fahrenheit. The plants can tolerate temperatures as low as the upper 20s for brief periods, but sustained cold can damage the foliage and flowers. The ideal growing condition is when daytime temperatures are mild and there's a notable difference in night temperatures, as cooler nights help prolong bloom time.

  • scissorsPruning

    The Hyacinth 'Royal Navy' requires minimal pruning, mainly deadheading spent flowers to promote bulb vigor for the following year instead of seed development. Once the flowers fade, cut the flower stalks near the base of the plant, but leave the foliage in place until it turns yellow and dies back naturally, usually by early summer. This allows the leaves to photosynthesize and store energy in the bulb for next year's growth.

  • circleLife cycle

    The common hyacinth, including Hyacinthus orientalis 'Royal Navy', begins its life cycle with a dormant bulb which breaks dormancy in the fall or early winter. The bulb roots actively before sending up a shoot as temperatures start warming in early spring. The shoot grows into a stem that bears dense clusters of fragrant, deep blue flowers. After blooming, which occurs in mid-spring, the plant enters a period of photosynthesis and energy storage as the leaves remain green and photosynthetically active. Once the leaves yellow and wither, the plant returns to dormancy in the summer, conserving energy within the bulb. The cycle repeats when the weather cools, and the plant prepares for another active growing season.

  • sproutPropogation

    • Propogation time


    • The most popular method of propagating the common garden hyacinth, particularly the Hyacinthus orientalis 'Royal Navy', is through the division of its bulbs, typically undertaken in late summer or early fall, after the foliage has died down. Gardeners separate offsets, also known as "bulblets", from the mature bulbs; these are small bulbs that form at the base of the parent bulb. The offsets should be carefully snapped or cut off – ensuring that each segment has a portion of the base plate for root development. Once removed, they are left to dry for a day or two to allow the wound to callus and reduce the risk of rot. The separated bulblets are then planted about 4 inches (10 centimeters) deep and at least 3 inches (approximately 8 centimeters) apart in well-drained soil and a sunny location where they can develop and reach flowering size in a few years.
