Care tips
This hollyhock thrives in full sun for optimal flowering, though it can tolerate some partial shade. It requires regular watering, especially during dry spells, but ensure the soil is well-draining to prevent waterlogging. It flourishes in fertile, well-drained, and slightly alkaline soils. Avoid excessive nitrogen fertilization, as this can promote leaf growth at the expense of flowering.
