This introduced ornamental wild flower bears panicles of funnel-shaped, blue or white flowers in July and August. But additionally it is a most unusual salad plant! It is grown both for its white, firm and crisp roots from October through winter and its salad leaves which are used like spinach. And another fact: The Brothers Grimm's tale of Rapunzel took its name from this plant!
For best results, seeds are sown directly into the ground where required in the spring. Alternatively, sow in late winter/early spring in gentle warmth, 15-20 degrees C. Prick out into small 3 inch or 7 cm. pots and plant in final position when the plants are established.
