Ipomoea tricolor 'Heavenly Blue': flower

Ipomoea tricolor, known in English as morning glory or grannyvine and in French as ipomée tricolor is a tender perennial* climbing vine native to the tropics of the Americas. The large trumpet shaped blossoms, which may be blue, purple, white, or pink, open early in the morning and close as the temperature rises. The cultivar shown, 'Heavenly Blue', has especially large blossoms in an exquisite true blue. Seeds are best directly sown in the garden after the last frost; soak them 24 hours before planting.
