Gardeners' Notes:

Neutral coriaceous On Apr 14, 2014, coriaceous from ROSLINDALE, MA wrote:

Rampion (as in the Rapunzel fairy tale), Campanula rapunculus, is a biennial that's long been cultivated in Europe as a tasty and versatile vegetable. It's the basal leaves and first-year taproots that are eaten. It's rarely grown in North America.

This plant grows between 18" and 3 feet tall.

Rampion (Campanula rapunculus) is frequently confused with the highly invasive perennial Campanula rapunculoides, which also has an edible root. The latter looks similar and has a similar sounding name---in botanical latin, the suffix "--oides" means "looks like---but it behaves very differently in the gardens and the woodlands of North America.

According to the USDA Plants database, rampion has never been reported to naturalize in North America, and is not invasive here.


This plant has been said to grow in the following regions:

Shawnee Mission, Kansas
