It is so fun colourful that it makes you happy when you walk past it. The hollyhock (Alcea rosea) has many colours, and they are all beautiful.
This plant with its colourful flowers prefers to be rooted in poor clay soil. However, if you live on sandy soil, try the darker shades, which also work well there. The roots of this plant are in Turkey. In the 16th century, it came to Europe where it grows surprisingly well in urban areas. Just look at all the narrow frontage gardens where it brightens up the whole street with its flowers in all colours.
