Answer: The answer to your question is "it depends". In general, hollyhocks are biennial because they grow vegetatively the first year and then flower and set seeds the second year. Some strains of hollyhocks exhibit more pronounced perennial tendencies while others are predominently biennial. Individual plants will also vary in performance according to their individual characteristics due to seed variation as well as their growing conditions. In some cases there are so many seedlings every year that the hollyhocks seem to be perennial when in fact it is a number of successive plants in a patch together. Hope this clarifies things for you.
