These perennial herbs are known commonly as wild hollyhocks and sometimes as globe-mallows (or globe mallows, globemallows).
The beds were planted with a seasonal mix of bulbs, annuals and shrubs such as gladioli, hollyhocks, tulips, pansys and azaleas.
The word "aoi" can also mean a hollyhock.
Perennial flowering plants include delphinium, hollyhock, lavender, and roses.
