Hollyhock seed from my English garden has produced flowers that have done well here in Spain. This bloom is from a second flush of flowers after the main stem was removed after dying back following the first flowering period. The pollen on the lower petal means that it has been pollinated by a visiting insect and will soon produce it's own seed.
Established Hollyhocks can suffer from Rust markings on the leaves so many growers sow new seed each year. The flowers are produced in the year after sowing.
