IPOMOEA 'CLARKE'S HEAVENLY BLUE'
This showy climber produces a seemingly endless succession of huge, 10-13 centimetre, white-throated blue trumpets. Plants climb to more than 4.5 metres, producing flowers which open in the morning before fading in the afternoon, from July until October.
Seeds may be sown at any time when you can give adequate heat and light but are best sown in early spring in a propagator, warm greenhouse or on a windowsill for late spring planting. Alternatively sow outdoors March-April.
