Answer: Thank goodness for my German ancestry! Rapunzel is Campanula rapunculus, also called Rover Bellflower. These seeds are available from Cyberseeds, PO Box 171102, San Antonio, TX 78217-1102. Just for fun, here's the listing from a German site: Campanulaceae =Glockenblumengewachse
Rapunzel-Glockenblume, Rapunzelrube; bellflower, little turnip, rampion; raiponce, rampon; raponzolo
Visit the site if you like:
All plants in the genus Campanula have edible leaves and some also produce edible roots. Most of them are easily grown in a well-drained soil in sun or semi-shade. One of the nicest is C. versicolor from Europe, the leaves are very acceptable raw, and are rich in Vitamin C. Also worth trying for their leaves are two British natives C. latifolia and C. persicicfolia. The North American C. rapunculoides also produces a nice edible root but this plant can be quite invasive.
Hope this answers your question!
