Crown Imperial is one of the most ornamental spring bulbs, which has captivated gardeners since the sixteenth century, when it arrived in Europe from the mountainous regions of Iran and Afghanistan. Its history in cultivation spans more than four hundred years, and its popularity shows no signs of waning. The distinctive dark, glossy bulb of this plant held the status of genuine exotica in European gardens of old and was considered a mark of refined taste.

The tall, stately plant unfolds in April and May in a truly 'imperial' spectacle: from the tip of the stem hang bell-shaped flowers in shades of orange, brilliant yellow, and deep red. The top of the stem is crowned with a tuft of upright green leaves, like a regal crown. Today, gardeners can choose from several cultivars, ranging from classic bright orange to delicate cream tones. Each plant creates an impression of an architectural sculpture in the garden.

In garden design, the plant is indispensable: its tall, defined form works beautifully among low-growing spring flowers, and equally well in mixed compositions with tulips and muscari. Crown Imperial fills that precious period when the earliest flowers have faded but summer has not yet begun. Interestingly, beyond its decorative value, the plant enjoys an excellent reputation among gardeners: wild populations have long known this secret, but garden pests—moles and mice—thoroughly dislike the bulbs and avoid them entirely.

If you have a garden corner where spring deserves a particularly exuberant beginning, the perfect place for Crown Imperial is already waiting.
