Vibrant, azure-blue, trumpet-shaped flowers, each with a white eye, open in the morning and last just one day, but appear in a continuous stream throughout the summer. This is a spectacular annual or short-lived perennial climber, that is ideal for training over a pergola or arch in a sunny, sheltered site.
How to care for Ipomoea tricolor Heavenly Blue:
Soak the seeds in water for 24 hours before sowing to soften them up and then plant 2.5mm deep into small pots filled with a freely draining compost. Keep them at around 20°C and water when necessary. Thin out carefully when large enough to handle taking care not to damage the roots and harden off before planting out after all frosts.
