Biennial or Perennial? Understanding Plant Life Cycles

Plant life cycles can be confusing, especially when modern breeding blurs traditional categories. Here's a quick guide:

Short-Lived Perennials

Delphiniums and some verbascums are perennials that bloom yearly for three or more years, though they may not live as long as peonies or hostas.

Classic Biennials

Most foxgloves are true biennials: they produce lush foliage the first year, then a dramatic flower spike the second year before dying.

The New "First-Year Blooming" Biennials

Modern hybridizing has created exceptions. You can now grow biennial foxglove ('Foxy') or hollyhock (Summer Carnival mix) that bloom the first year when planted from seed in spring, followed by a second year of bloom. These varieties give you the best of both worlds—instant gratification plus a return performance.
