perennial yellow hollyhock (Alcea rugosa) Perennial. Zones 3-8. This is a Russian variety of hollyhock. It grows to 6' and bears a multitude of single, pale yellow flowers. It requires full sun, water when dry, and likes to have good fertile soil. I've seen references that this is supposed to be very resistant to rust, but I've not found that to be true. It is one of my favorite hollyhocks and it's a bonus to me that it is a perennial. I particularly like it planted with pink hollyhocks.
