Hollyhocks are the tall, sturdy perennials often found in ornamental gardens. These flowering plants produce colorful blooms biennially and set a multitude of seeds. Hollyhocks are easy to grow and offer a strong vertical accent to flower beds and gardens.
The hollyhock is related to the hibiscus
Hollyhock rust is prevalent almost everywhere hollyhocks are grown. Air currents and rain carry fungal spores to healthy plants in other locations. The fungus can also overwinter with plant debris, infecting new plants that emerge in the spring.
Hollyhocks are hardy, drought-resistant plants. They thrive in full sun in locations that might be too dry or too hot for other plants. Excessive humidity or dampness encourages the spread of hollyhock rust among the plants.
