Cichorium intybus var. foliosum 'Rossa di Verona' · also called Verona radicchio, round red chicory · edible

'Rossa di Verona' is the classic round-headed radicchio, forming a tight cabbage-like ball of deep red leaves veined with white.

Mature size: 15-25 cm tall, heads roughly 10-15 cm across

Indoor size vs how big it gets in the wild

Indoors and in a pot, expect 15-25 cm tall, heads roughly 10-15 cm across. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

It sizes up fast and once, racing from seedling to full size in a single season; after cropping it is finished, so size is a within-season question.
