Hollyhock

From the breeding work of Thompson & Morgan comes this new series of hollyhocks that was 16 years in the making. These varieties were selected and hybridized over many generations for their large, single, bicolor flowers. Each displays a prominent, contrasting lighter or darker colored halo in the center of the flower. Members of this series form a bushy clump of rugose green foliage with tall spikes carrying large, colorful blossoms in early to midsummer. Alcea rosea 'Cerise' has large cerise flowers with a vibrant deep purple halo.

Growing and Maintenance Tips

Hollyhocks prefer rich, moist but well drained soil in full sun. Once established they are somewhat drought tolerant. Because the foliage can be attacked by insects and foliar disease Hollyhocks should always be located where their "knees" will be covered by other plants. They may need staking in very windy sites but if they are at the back of a perennial border this is usually not required.
