Gladioli 'Black Surprise'
This captivating bulb produces tall, upright spikes of richly coloured blooms in deep burgundy tones so dark they appear almost black. Flowering through summer in southern climates, it brings a sense of drama and sophistication to garden plantings.
Ideal for full sun and well-drained soil, it performs beautifully in borders and is especially effective when planted in groups for a bold visual impact. Its striking vertical form adds height and contrast, pairing well with lighter or pastel-toned flowers for a balanced display.
The long, sturdy stems make it an excellent choice for cut flowers, adding depth and elegance to floral arrangements. For best results, provide consistent moisture during active growth and choose a sheltered position to protect the tall spikes from wind. Plant in succession to extend the flowering season and enjoy continuous bursts of dramatic colour.
