hollyhock rust
July 9, 2014

Hollyhocks are grown for the their showy, colorful flowers. A common disease problem on hollyhocks, called rust, can also lead to 'colorful' foliage.  Several specimens have been brought to the Washington County Extension office recently.   The rust fungus causes raised brown spots, usually pinhead-size or larger, on the undersides of leaves. The upper leaf surface shows orange to yellow spots. The raised spots may coalesce, killing larger areas of leaves.  Orange pustules also form on the stems of the plants.
