Some are short-lived perennials as Arlene says but some are biennial, forming a growing crown the first year and flowering the second so need to be regrown from seed each year.

Hollyhocks will rarely flower in the first year unless sown incredibly early. Don't know about 'short lived' but we've got hollyhocks over six years old still blooming well (though it's possible they've self-seeded in the same spot... it's hard to say)
We're growing a black one this year, very beautiful!

~it should grow again next year but will probably need feeding and maybe covering over if we have another winter like last~lost mine after about 5 years~ was a lovely black one and would tower over everything!
