Hollyhock flowers “closed”

Question

Our hollyhock plant has grown to a height of about 8 ft and a few flowers appeared lower down the plant. However, after a couple of days (in sunlight), they have decided to close up whilst still looking healthy. The plant is situated on a north facing wall in decent soil. There are other buds waiting to open. Is this normal, or might we have a problem? Many thanks in advance for any suggestions. Tom.

Answer 1

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.
