Late spring can feel a little too pastel until Tulip 'Blue Diamond' steps in with its deep, composed purple blooms. Growing to around 40cm, this double-flowered tulip forms a tidy clump of pale green, lance-shaped leaves, above which the double flowers open with generous layers and a soft, rounded fullness. As the blooms mature, their rich colouring develops subtle grey-silver tones, giving Tulip 'Blue Diamond' a changing, atmospheric quality that keeps the display interesting for longer. It is refined rather than loud, dramatic rather than flashy, and all the more appealing for that quiet confidence.

Use Tulip 'Blue Diamond' to bring depth to borders, especially where softer spring shades need grounding with something cooler and more intriguing. It looks beautiful with blush pink, ivory, lilac, silver foliage and fresh green, and its late flowering season makes it useful for bridging the gap between classic spring bulbs and early perennials. In containers, Tulip 'Blue Diamond' creates a neat, polished display, while in a vase it offers a wonderfully layered flower with an elegant, almost antique mood. For gardeners who prefer their tulips with richness, nuance and a touch of mystery, Tulip 'Blue Diamond' is an excellent choice.
