Physalis alkekengi is an ornamental plant, appreciated for its original fruits. Caged love takes its poetic name from its particular fruits, enclosed in a chalice which, as it matures, reveals a red-orange fruit.

Its other nickname, the Japanese lantern, evokes these famous lantern-shaped chalices, which are first bright red before becoming transparent. Physalis is propagated rather by division or by sowing (the seeds can be sown in March or April) but it can also be taken from cuttings.
