Hollyhock
Alcea rosea
Hollyhock is the quintessential cottage garden vertical — towering flower spires in purple, red, and yellow that have anchored garden borders since the medieval period.
Native to Turkey and western Asia, Hollyhock arrived in European gardens centuries ago and has never left. A biennial or short-lived annual in the mallow family, it grows 5 to 8 feet tall on rigid, self-supporting spikes that need no staking. The flowers are large, ornamental, and come in a wide range of shades from soft yellow through deep burgundy, blooming over a long period from June to August. Plant in full sun to light shade in moist, well-drained soil rich in organic matter. Once established, Hollyhock reseeds readily enough to return reliably year after year without any effort.
The round, softly lobed leaves can reach 8 inches across but are susceptible to rust, leaf spot, and anthracnose, and often look tired by late summer. This is unavoidable in humid climates and best managed by siting plants where airflow is good. Slugs, spider mites, and Japanese Beetles can all cause trouble. None of this detracts from the plant's usefulness in pollinator gardens, cottage borders, and tight spaces where height is needed. Bees work the flowers enthusiastically. It tolerates black walnut toxicity, which expands its planting options considerably.
