The hollyhock enjoys being in the sun but is happy with some shade. Make sure the soil is rich and somewhat moist, if you want the plant to thrive. Just before you plant be sure to add well-aged manure or compost as this will help the plant grow.
If the weather is dry it is vital to provide water if you want them to flower. You can plant hollyhocks near a rain barrel if the site gets sufficient sunshine. They can help beautify the spot and this will make regular watering easier, provided, of course, that it rains.
The hollyhock flower is edible and would look great in a salad. I prefer to leave them on the plant and enjoy them visually but it is good to know that they have a secondary purpose.
The hollyhock is an ideal plant for the back of the border along the fence and especially with chain link fences can help serve as a privacy screen.
