Biennials are betwixt and between annuals and perennials, usually putting out roots and foliage the first year of growth, blooming the second year, then dying, while self-seeding for the next year's plants. 'Pomponette Red' will bloom the first year from spring into early summer, then will usually self-seed for a return the following season. Deadheading will prolong the production of these dome-shaped flowers, but keep some spent flowers to encourage self-seeding for next year.
