Description
Gladiolus ‘Black Surprise’ is a long summer bloomer that flowers in July and August and maybe even beyond. This is an unusual large-flowering, Gladiolus bursting with dark burgundy petals with large edges of black and a dark throat. Gladiolus Black Surprise is unique and would be a welcome addition to any summer gardens. Gladiolus tubers should be planted about 7-10 cm deep in the spring. This allows rainwater to drain well under the tubers. Space the tubers about 10-12 cm apart. Add some good potting soil when planting. Mix heavy (clay) soil with sharp sand before planting. This large-flowered Gladiolus likes to grow in a warm sunny spot. This Gladiolus has a beautiful colour and is easy to combine. You can make special combinations with it in the border with tall perennials and Dahlias. Preferably plant Gladiolus in a different spot every year.
