Why Hollyhock Behaves Like an Annual in India When It Isn't One
Hollyhock is naturally biennial in temperate climates, growing foliage in its first year and only flowering in its second, but India's warmer, faster growing conditions frequently compress this into a single season, which is why it's commonly sold and grown here as if it were a straightforward annual. Growers expecting a slow two-year build-up are often surprised when a hollyhock flowers and finishes within one year instead, while growers unaware of the biennial habit sometimes give up on a first-year plant that's only building foliage and hasn't bloomed yet, not realising it may need a second season in cooler climates. Rust, a fungal disease that shows up as orange-brown spots on the lower leaves, is especially common on hollyhock during humid monsoon months, and removing affected lower leaves promptly slows its spread up the stalk far more effectively than any general-purpose treatment.
