    Yellow hollyhock are actually not that rare at all and colors vary with
    shades of carmine-rose, crimson, lemon, lilac, pink, purple, bicolor and white. In fact, one of the rarest hollyhock colors is black (Alcea rosea nigra--actually very dark purple or dark red).

    This is typical, particularly if they have been well pollinated. The purpose of the flower is to attract pollinators and once pollination is done, the plant will go onto produce the seeds. You can help encourage more flowers by removing the closed ones as the plant will feel it needs to produce more flowers to produce seeds.

    Hollyhocks can be successfully grown in zones 3-8. You should be in zone 4, and could be well grown in your area.
